Another axis for the Boxford 125TCL

Watch the video of Stuart Tankard making tiny valve handles on his CNC lathe.  Changing the old Boxford spindle motor to a new generation servo motor allows him to use Mach3 to control the spindle to turn very slowly and to a set number of degrees, producing the very attractive handle cut-outs and rim dimples.  i.e. he has added the functionality of an indexing head to his CNC lathe.

It required adding a small milling head and motor to the toolpost.

I can see one of these on my Boxford 125TCL in the near future.

Trevithick Dredger.. attaching the flywheel and driving gear to the mainshaft.

The flywheel and driving gear both are attached to cranks which join the connecting rods to the mainshaft.  It is important that both cranks are attached with the same angularity.   Seems simple.  The cranks are identical.  But small taper holes, through brass and silver steel.

Drilling the 2 holes took most of the day.

Figuring the setup was the biggest challenge.

IMG_7329.JPG

This is the setup on the milling machine.  The mainshaft is cramped on parallels, and ends of the cranks are resting on smaller parallels.   The square sections of the cranks have been centered.

First problem was that the 2.5mm drill bits were not long enough for the chuck to clear the gear.   I did not have adequately small ER collets (would have required ER8’s), but I did have a Dremel chuck which was small enough.  But no spindle for the Dremel chuck.  The Dremel chuck has a really odd thread.  I measured it at 40tpi, and 7.05mm diameter.

So I made a spindle.   Thank goodness for CNC threading.

IMG_7331.JPG

The Dremel chuck and the shop made spindle.

IMG_7330.JPG

Dremel chucks are convenient, but they are not very accurate.  Fortunately, once the hole was centred, the drill bits and reamer seemed to follow the centred start.   Here I am about to ream the hole which has 3 steps   2.5mm, 2,8mm, and 3mm.   The shop made spindle is held in the milling machine drilling chuck.

I took the reaming very gently, not wanting any broken bits of high speed steel stuck in the workpiece…. and all was well.

IMG_7333.JPG

And here is the gear crank pinned to the mainshaft.

IMG_7334.JPG

And this is the setup for the flywheel end.   Fortunately, by good management or good luck, I was able to remove the flywheel, leaving half of the crank insitu, for drilling reaming and pinning.

IMG_7328.JPG

I spent some time assembling the cranks and testing the rotation movements.  It does rotate, but there is still some sticking on the guides, the cause of which I have not identified/isolated.

So I sat back and enjoyed one of my Xmas presents.   Ah!   Bliss!

Making a Lead Ball for the safety valve

The deWaal plans for the Trevithick Dredger Engine call for a 30mm diameter lead ball for the safety valve.

I considered substituting steel or brass, and turning the ball, but lead is almost 50% more dense than the other metals, and that could be detrimental to the functioning of the safety valve, so I worked out how to make the ball in lead.

I have previously cast lead balls 14mm diameter, but this is significantly bigger.  I did briefly consider making a plaster of Paris mould, but I could find no balls of the correct diameter for the POP mould, so I decided to mill the mould.

On rummaging through my big milling cutters, I discovered that I have a ball nose cutter, 31.75mm diameter.  It was part of a package of cutters which I had purchased years ago, and almost forgotten.  I had bought the cutters BY WEIGHT.  I think that I paid $US5 per pound, and I bought 20lb.  Mostly the cutters were resharpened end mills, but one of them was an unused 31.75mm ball nose.  Pretty close to perfect for this job!

IMG_7302.JPG

First I cut off two 25mm lengths of 40mm square solid alu bar.

IMG_7305.JPG

Then milled them pretty close to square and identical.

IMG_7308.JPG

Then used the 31.75mm end mill to make a hemisphere in each alu blank and drilled and tapped for a 5mm cap screw in each corner. 

IMG_7309.JPG

On the left is the mould, screwed together, with a hole drilled into the spherical cavity.  Here I am heating it in a frypan, ready to accept the molten lead, which is being prepared in the cast iron saucepan on the right.  I hasten to add that SWMBO knows nothing about this.  Those utensils are part of my workshop gear, and will never be used for human consumption.  SWMBO does not read this blog, so I am safe.  I hope.

IMG_7312.JPG

From my previous experience with lead castings, I have decided that the mould should be 250-300ºc so the lead will not solidify in the small entry hole, and also to minimise the formation of voids in the casting.

IMG_7313.JPG

Here is the molten lead after pouring.  It is still liquid.

IMG_7315.JPG

And after cooling and splitting the mould.  The hemispheres were not exactly aligned.

IMG_7319.JPG

And there was a big void.  I could have filled it.  But I decided that if I made the mould even hotter, it might work better, so I made another lead sphere.

IMG_7325.JPG

The next one, on the left, worked perfectly.  I heated the mould to 300ºc, and no voids at all.   I also reversed the bolting positions which removed the hemispherical misalignment. Drilled and tapped for the supporting ring.

IMG_7326.JPG

And here is the weight in its final position.   I dropped it, resulting in a Death Star indentation, which I kind of like.  A little bit of polishing will remove the latitude lines.

Only one part for the day’s work again.  But it was a LOT OF FUN!

 

 

 

How Many One Off Parts Can You Make Per Day?

Obviously it depends how many machining operations are required per part, but these days I find that one or two parts per day is about all that I can manage.  That includes deciding on then finding the material,  drawing up the part in CAD, mounting the material and the cutter(s), then machining and finishing time.

Take today for example.  My aim was make a steam pressure valve for the Trevithick Dredger Engine.   It consists of a lead ball weight 30mm diameter, a lever arm with a hook, a simple stand with a M6 male thread, a movement restrainer, and the seat and valve.  6 fairly simple parts.  I thought that I might get it all done in one day.

But at the end of the day, all that I had made was the arm, stand and restrainer.  3 simple parts.

IMG_7299.JPG

The pressure valve arm, stand and restrainer in place.

Admittedly the arm is stainless steel of unknown grade.  I broke 2  (4mm) cutters before I had slowed the milling feed rate to a snail’s pace 40mm/minute.  Machining time for that part was over an hour!  Then at least another hour of hand filing and finishing.

It is just as well that the worst day in the workshop is better than the best day of working!

And next will the interesting job of making the 30mm diameter lead ball weight.  Still thinking about that one.

Boxing Day in Oz

So, Xmas day was great.  Perfect weather, middle daughter’s home and vegetarian cooking thanks to her husband and all guests, and limitation rules for presents so that aspect was not gross.  And SWMBO agreed to be designated driver home.   So I could freely partake the lovely Aussie big reds.   And whiskeys.   And best of all… cigars.

Don’t remember much about the trip home.   But apparently we made it because I woke up with a dry throat but no headache. Must have been good reds and single malts.

Then best of all…. Boxing day!   Means that it is all over for another year.

A slow start to the day, then a half day in the workshop.

I spent several hours measuring various dimensions of the build to date.  Although I had been careful to keep the dimensions correct, the cross head was sticking and jamming on the slides.   Some dimensions were out by up to a millimetre…   mainly due, I suspect, to movements during the big silver soldering sessions.

So I tried various permutations and commutations to minimise the aberrations.  And started introducing brass shim strips to remove the aberrations.

And It gradually started to improve the situation.

IMG_7283.JPG

Shims under the base, and between the base pieces and the boiler.

Then I installed the valve timing mechanism.

But…..  it fouls the domed end of the boiler.

What to do?     After a lot of messing around, trial and error, swapping components around, I have decided to remake a couple of components AND to ease the fit between a couple of the others.    At least the cross head has stopped jamming so I am winning.

IMG_7284.JPG

Close up shot of the valve switching mechanism.

IMG_7285.JPG

The photo shows a vertical mark where the mechanism is scraping along the domed boiler end.

IMG_7286.JPG

where I left it for the day.  Will give it a miss tomorrow…   very hot day predicted.

 

Trevithick Dredger Engine.. the steam valve operator.

IMG_7268.JPG

I did not know what to name this assembly.  It attaches to the cross head, and pushes the handle of the steam valve up and down each revolution to admit and release steam from each end of the cylinder.

It uses the U shaped metal strip which I cut out and bent yesterday.   It is 230mm long, and I made it from brass, including the filler strips which actually contact with the valve lever.  I made the filler strips a few mm longer than necessary, so I can file them as necessary when the engine is timed.

Trevithick Dredger Engine.. the firedoor fittings. Or silver soldering tiny pieces.

Another day in the workshop.

Yesterday I  bolted the latch to the door.  But how to attach the catch to the surround, and the restraint to the door.  The plans call for tiny screws, but that method did not appeal.  I decided to silver solder them in place.  Silver solder is immensely strong, and does not require tapping and threading minute screws into position.  The problem with silver solder is that some parts of the firedoor are already silver soldered, and I did not want to risk undoing that previous solder.

So, I used a heat sink.

IMG_7260.JPG

The catch is held in position by pressure from the latch.  I did NOT want to melt the solder of the hinge, so I rested a sizeable block of brass on the hinge.  Pure copper would have been even better.  Then, as I was soldering the catch, any heat travelling toward the hinge would have been absorbed into the brass heat sink.

IMG_7261.JPG

A staged shot, after soldering the catch was finished.  I was careful to keep the flux just in the joint which was to be soldered, to avoid the solder running into other areas.

IMG_7262.JPG

A close up of the soldered catch.  The iphone camera is pretty good hey?  That catch is only 3mm wide.   A bit of filing and finishing needed.

IMG_7263.JPG

And the finished door.  Looks OK IMO.

The next job for today was to machine a strip of metal 6mm wide, 2mm thick and 600mm long.  I decided to make it from brass because I have a sheet of brass the correct thickness, and I was already thinking about the tight bend which was going to be required.

IMG_7265.JPG

So, I bandsawed a strip of brass from the sheet, about 50mm wide.  Then removed the milling vice and universal divider from the milling machine.  I am amazed at how those items are becoming heavier with age!    Then cramped the brass strip to the table and machined the sawn edge with a 6mm end mill which protruded into the milling table slot.  Fortunately I managed to not enlarge the T slot during this procedure.

IMG_7266.JPG

Then moved the brass strip, and indicated it parallel.  Then used the 6mm endmill to cut off the 6.5mm strip.  Probably not very efficient, but it worked, and the strip was correctly sized and dimensioned.

IMG_7267.JPG

Finally, annealed the middle of the strip, and bent it around a 5mm thick piece of steel, with a rounded edge.   This will become the fitting which operates the steam inlet/outlet valve.

Trevithick Dredger Engine ….Con Rods

I had previously bent the brass U pieces which hold the split bronze bearings to the wooden connecting rods.  I had also made the con rods and the bearings.  Today’s job was to fit them all together.

IMG_7180

Bending the U pieces on my shop made bender.

IMG_7182

And the Jarrah con rods.  The U pieces need to be shortened.

IMG_7250.JPG

With the bearing in place, measuring the amount of shortening required (approximately).

IMG_7251.JPG

Using an end mill to shorten the U piece arms.  Note the paper between the workpiece and the vice jaws.  That reduces the chance of the work moving.  How do I know?  Dont ask.

IMG_7254.JPG

The holes are carefully drilled M4 through the U piece and the wood.  Stainless steel square nuts on SS threaded rod.   Then the bearing was reamed again to the finish dimension.  I have yet to make the wedges which hold the pieces in position.

IMG_7257.JPG

The (almost) finished connecting rods.

IMG_7258.JPG

And a test installation on the engine.  A bit of workshop clutter to add to the atmosphere.

IMG_7259.JPG

And I had a bit of daylight on this beautiful summer day, so I made and installed the firedoor latch.

I am hopeful that I will have this engine running before I say goodbye as my subscription to WordPress finishes.  Not exactly sure when that will happen, so if I suddenly disappear, do a search on YouTube for the video of it running on steam.    Still a fair bit to do before that happens, but things are progressing!

 

Trevithick Dredger Engine… hinges for the fire door.

No big deal?  This “little” task caused me quite a bit of heartburn.

I had redesigned the flat face of the boiler, including the door and had not really thought through the door design and hinges.

Needless to say, the original hinges as designed by Tubal Cain and Julius deWaal, were quite incompatible with my redesign.

There are NO original drawings of Trevithick’s original designs of this face.  The Rees Cyclopedia drawings do not include this face, and it is hard to tell if the London Science Museum reconstruction is original in this respect.  I did read somewhere that the firedoor in his engines was a casting, so I did not feel bad about silver soldering components to build up the final parts.

In the end, after a failed effort at making a hinge, I decided to wing it, and make something which would work.

IMG_7243.JPG

This is my interpretation of a Trevithick fire door hinge.  No idea if it approximates Trevithick reality, but I suspect that no-one else knows either.

The tricky bit was silver soldering the 5mm brass tube bits to the appropriate base, and not getting silver solder into the hinge itself.

It was tricky, but it works!!

 

IMG_7247.JPG

The latch, the catch, and the movement restrainer come next.  The hinge pin is the cobalt drill which I could not release after the soldering.  Oh well…  cobalt steel should work well.   Incidentally, the stainless steel cap screws will be replaced with studs and square nuts when I around to it.    Now thinking about the propane burner and tubing.

 

Antartica Again!

Large sections of Antarctica have been suddenly hidden from view on Google Earth Pro, using fake clouds and checkerplate patterns.

They ARE fake because 1. they appeared suddenly (just a day after I had posted photos of strange objects, with coordinates, and the “clouds” neatly covered the areas about which I had posted.   2. the “clouds” are present, despite turning off atmosphere in GEP.  3. the “clouds” are present in all dates of the timeline, extending back 20-30 years, and the cloud pattern is unchanging over those decades.

Well, the fake clouds are still there, obscuring the interesting area, so I spent some time looking at a nearby area beyond the clouded area.

Screen Shot 2018-12-21 at 10.41.11 am.png

The red and yellow placemarks are those which the “clouds” and the “checkerplate” neatly cover.  The blue placemarks are those placed by me today.  They are not obscured, yet.   Take a look at what they are showing in the following photos.

Screen Shot 2018-12-21 at 10.40.38 am.png

Zooming in a bit, still 665km above the surface, showing the position of the blue placemarks.  The checkerplate line zigzags across the screen and everything to the left is deliberately (IMO) obscured.    Scale is bottom left, and compass top right.

Screen Shot 2018-12-21 at 10.37.38 am.png

Look at that straight line of odd objects.  I counted 28 of them, at about 1 km intervals.  From 14km above the surface.   Maginot Line?

Screen Shot 2018-12-21 at 10.36.45 am.png

Zooming in closer.  Same again!  300m long, 200m wide, black centre, grey objects surrounding.   Still 2006.  They appeared in 2004 and disappear 2008.  2006 is the clearest year.   From 5km above surface.

Screen Shot 2018-12-21 at 10.33.47 am.png

And another.   Dozens of them in this area.  These are NOT natural features.

And the huge black rectangular object which is still showing in Google Maps…

Screen Shot 2018-12-21 at 10.47.58 am.png

 A Google Maps image said to be taken in 2018.

Open your eyes people.  There is stuff going on, and we are not being told.

More Trevithick, and Xmas

The last 20% of the build takes 80% of the time.  Someones law.  But SO true.

I should be Xmas shopping.  But frankly, buying stuff which costs money, is not wanted or appreciated, takes time, and should be donated to people who really need it….  irritates me.

At least the adults in my family have taken a sensible decision to randomly allocate one person to buy a present, for one person only, to a maximum amount.

But it does mean that the one present should be meaningful.

I decided on something that my allocated recipient might like.  A bit unusual.  Something they (he or she) would never normally buy, and should make an impression.  But there was a catch….  I had to drive to the shopping centre, park, find the shop, and buy.

So I looked up the shop on the computer, noted the address, drove there, parked, paid parking, walked several hundred meters, and could not find the shop.  Walked for about an hour.   The shop no longer exists.  It has closed and they have not changed the Internet info.  Bummer.

But at least I actually own one of the items.   It is a bit old.  Actually about 40 years.  But it is in good condition.  so I will wrap it and give it.  And hope that its aged condition is not  detrimental.

My allocated recipient is the au pair, from Italy, aged 19, who lives with and looks after some of my grandchildren.  She is a lovely girl, and I believe that she is really enjoying her stay in Australia, with my youngest daughter and her family.

The present is an Australian flag.  I hang it on out front gate every Australia Day.  I hope that she sees it as a compliment, and a memory of her stay in in Oz.

I will buy a replacement for myself.  It will probably be made in China, but so what?

So today I had a few hours in the workshop after wasting a half day in the shopping mall.

Preheater tube 2.JPG

And made and installed the water feed tube from the pre-heater to the boiler.  I had made the clack valve in my previous session.

Preheater tube.JPG

I find that it is actually quite tricky to make the bends in exactly the correct place, with exactly the correct angular bends, and to silver solder the flanges at the correct angles.   This one worked out well.   I usually bend a piece of aluminium wire to roughly the correct dimensions, on which to base my copper tube bends.

Finally, normally, I detest Christmas (actually it is Saturnalia, a pagan roman festival).  The commercialism, the waste on presents, the killing of turkeys, pigs, sea life.   It is all gross, and I hate it. Yes, I am a grinch.  Once, I just refused to take part in it, but the fall out was immense, and I am not strong enough to repeat that protest.  But this year, my adult children have made a decision which makes me immensely proud.  They have decided to limit adult presents to one per person, (the grandchildren still get heaps), and the meal will be vegetarian.  A step in an wonderful direction.

 

Trevithick Dredger Engine… No more aliens, just a gear

Another few hours in the workshop, and I made the spur gear which transmits power to the dredger bucket chain.

I chose bronze, because 1. It will not rust 2. It machines fairly easily 3. I had some in the correct size!

I did think about whether to CNC mill the gear, or make it on my lathe and form the teeth with a custom built cutter.  In the end, I decided to CNC mill the entire part.   The plans called for a tooth shape which looked like an Acme threaded part.  I decided that Trevithick would NOT have made it like that, nor would he have known about pressure angles, and parabolic tooth shapes, so I winged it and drew a shape on the CAD which was a bit between both.

Gear blank.JPG

As you can see it is a blank of bronze which I bought at scrap price from a local supplier.  Here centering it on the CNC mill using a Starrett wobbler.

Roughing the shape was with a 6mm 4 flute carbide cutter.

 

And finishing, to impart the fine fillets, was with a 3mm carbide cutter, taking 1mm depth bites.  I broke one, but the next one, new, finished the job intact.

 

And here is the gear, still attached  to the bronze rod.  Now, how to detach it?

Gear 0n blank.JPG

The blank gear still attached to the bronze rod.

Gear parting.JPG

So I started by using a parting blade, but I chickened out when it had plunged about 12mm.

Gear bandswing.JPG

So then I parted the gear from the bronze rod on the bandsaw.  It was a bit tricky… became quite hot.

Gear bandsaw result.JPG

After bandsawing, I counted my fingers, 9, hang on there’s another, so 10.

gear surfacing.JPG

Then I surfaced the back of the gear on the mill.  Actually, I tried gluing the gear to a silver steel rod, and turning the back face, but the glue did not survive.  So I resorted to this solution which worked fine.

Gear with crank1.JPG

And this is the gear, with the crank push fitted.  pretty neat hey!

gear with crank2.JPG

And the inside face.  Some filing required to remove sharp edges.  Or maybe I will put it in the gemstone tumbler for a couple of hours.

Hey, no aliens!  But watch this...

Trevithick Dredger Engine.. connecting the water pre-heater

A few more hours in the workshop today.

IMG_7224.JPG

The steam exhaust from the engine passes through a tube to the chimney.

Since this was the worlds first “strong steam” (high pressure) boiler, the water level in the boiler needs to be constantly replenished.

Trevithick thought that the water coming into the boiler could be preheated by the exhausted steam.  So he conceived a double tube, with the exhausted steam exiting through the inner tube, and the water being pumped through the outer tube….  A heat exchanger.  It was awkward to make using modern heat sources and silver solder.  I can only imagine how it was made 200 years ago, using castings and black-smithed iron panels.

The users noticed that the steam which was injected into the chimney improved the coal fire.

IMG_7225.JPG

The cap screws are temporary, until I replace them with square nuts and stainless thread.

The hardest part of these connection pieces was keeping the flanges square to the 1/4″ copper tube while silver soldering them.    Any clever methods out there?

Back to the Trevithick Dredger Engine. No aliens… promise.

OK, it is not just the fascination with Antarctica and whatever it is that is going on down there, and that they are NOT TELLING US!

But SWMBO has insisted that I assist with the renovation currently going on with an investment property.  Unfortunately, I am very handy with all sorts of skills which she finds useful, like assembling flat pack kitchens and laundrys, and welding broken windows, and winching crooked concrete steps, and removing rubbish in my ute (which is now fixed after the failed thieving attempt).

But I managed to grab a few hours in the workshop today, so I made the pre-heater for the boiler water feed.

This was another Trevithick invention, using the exhausted steam  to heat the water before it is pumped into the boiler.

It is a tube within a tube, and the inner tube (copper) has separate inlet and outlets, each with its own flange.

IMG_7223.JPG

IMG_7221.JPG

It looks simple, but it has 10 parts.  All silver soldered.  Too many to solder in one heating session.  It needed several redos before it was satisfactory.  But seems good.

IMG_7220.JPG

There!  Did not mention aliens once.  But did you see this video…just watch it!

Antarctica Again. Bear with me. This is so weird.

OK, I will get back to the metal working soon.  I promise.

But this is so odd that I have to record it.

Reader Richard  thought that I would be interested in this Antarctic site, which was recorded on YouTube a few years ago.  The original YouTuber, thirdphaseofthemoon,    was lampooned in the comments on his post,  having called the site a “mega alien city” but I believe that this site could be significant for a different reason.

Go to 75ºS 0ºE (not exact but close enough.  The exact coords are in the screenshots which follow.)

And the following screen shots go back in time.  Just bear with me.

 

Screen Shot 2018-12-14 at 11.06.29 pm.png

Note the fake cloud cover which appeared a few days ago.

 

The area of interest today is at the centre of the screen, and is marked 75ºS0ºE.  Note that it is in the middle of the shapes which I posted yesterday.

Zooming into this spot using the most recent Google Earth photos shows this..

Screen Shot 2018-12-14 at 10.54.06 pm.png

Now you have to admit, that is unusual!  A flat, snow covered plain, with a bit of a hill, and a straight row of somethings, at regular intervals, about 2km long.  And a hole of some sort to the NE.   Stay with me!!

Screen Shot 2018-12-14 at 10.56.13 pm.png

These images are from 2016.  Close up, each “something” appears to be a hole.  The V shaped patterns to the SW I believe to be snow patterns, formed by the prevailing wind.  Note the reddish discolouration.   (Please check this out in Google Earth yourself!)

Screen Shot 2018-12-14 at 10.54.55 pm.png

And this is the big hole/cave mouth/whatever to the NE.   All a bit puzzling.   So let’s go back in time.   Google Earth does not make this exercise easy, because images disappear, and you have to zoom out, then in, but it can be done with persistence.

Screen Shot 2018-12-14 at 5.07.38 pm.png

Well, look at that.  2013.  The same spot.  An airstrip, some well travelled tracks,  excavations in the region of the big hole/cave mouth, and if you zoom in, you can see some machines.  Note the red discolouration again.  I have no idea what that colour is caused by.

Now we go back through some years….

 

Screen Shot 2018-12-14 at 5.12.12 pm.png

2012.  Before the excavations.  Look at the shape of the mound under the snow.

 

Screen Shot 2018-12-14 at 5.09.20 pm.png

Closer, 2012

 

Screen Shot 2018-12-14 at 5.12.31 pm.png

2011.  Note the shape before the excavations.  What does it remind you of?  Possibly a V shape or a chevron?  Does it remind you of some of the UFO’s which have been video’d in YouTube lately?    Hang in there, it gets better!  The chevron appears first in the satellite pictures of the area in 2001.

The oldest Google Earth image which I could obtain of the area was from 1984.  It is slighly north of the 75ºS 0ºE area of the later chevron and the excavations.  What do you see?   I see lots of coloured objects, with the same shapes, and differing orientations.  I do not believe that these are natural features or swamp gas.

Screen Shot 2018-12-14 at 5.17.16 pm.png

1984, close to where the chevron shaped mound later appears.

 

And close up

Screen Shot 2018-12-14 at 11.39.02 pm.png

These “objects” are about 60 x 150 meters big.  Pinks, yellow, green.   And they are located around the region of the chevron shape, and nowhere else that I can find!  What are they?

So, what have they found, and are excavating in 2013?  Dare I say it?  Well it looks like a UFO shape to me.  The 2013 regular row of holes and the big hole, I suspect are human efforts to investigate whatever is buried, without obviously displaying it to observers like us.

And I have no idea what the 1984 coloured objects are.

 

 

Why the SECRECY about ANTARCTICA?

Google Earth has suddenly obscured the area in Wilkes Land Antarctica with “cloud” cover.  Turning off “atmosphere” in the Google Earth settings does not remove the “cloud” cover.  Scanning back and forth over the years 1954 – 2016 does not remove it either.  It remains unchanged over the years 1954-2016.

The cloud cover has a checkerplate edge.  It does not have a realistic appearance.

Also, it conveniently and almost exactly covers the placemarks on the map of Antarctica which I posted a day or two ago, which show the location of the odd rectangular shapes.

But, today, I have scanned other areas of Antarctica and found a lot more of the rectangular shapes in a non obscured area.   See the screenshot below.

Screen Shot 2018-12-13 at 10.48.02 am.png

The odd shapes appear only in the years 2003 to 2006, so if you want to check this yourself, use the timeline.

In the picture above, the unobscured area is at the 12 o’clock position.  It is south of the South Atlantic ocean if you are looking for it.   The co-ordinates are in the screen shots which follow.    The huge black rectangle and surrounding shapes are in the area which is now hidden by the “cloud” and checkerplate. (at the 4 o’clock position in the picture above).

I am certain that these shapes are not natural features for the following reasons…  1. they appear only in the years 2003-7; 2. they do not have a similar appearance to other natural features such as non snow covered mountains;  3.they do not appear in any other snow covered areas that I have searched such as Greenland, Novaya Zemlya, Alaska; 4. they have remarkable consistency of size and similarity to each other of shape;  and the fact that someone appears to have attempted to stop other Google Earth users from seeing them.  So take a look before the next cluster is covered with “cloud” or checkerplate.

For the public record I have taken screenshots of 30-40 of the shapes, and I am posting some of these below.   The coordinates of each one is at the bottom of the screen in each case.  The are mostly taken from a height of about 4000 meters.

The first 4 shots are of the same location, over 4 years.

2007 gone.  Never to be seen again.

Now some more, but only in 2006, which was the clearest year.

They are all close to north-south orientation.  Note the projections from the central black area and the barely visible grey shapes in the white rectangular surrounding area.  The white area usually measures 300m x 150m or 200m.

This group are natural features, from the same altitude and of a similar size.

Some of the rectangles are in close clusters, but most are are separated by many kilometers.

And this group (from a higher altitude) forms a straight line.

Some are in more rugged terrain

There are hundreds of these over the surface of Antarctica 2003 – 2007.

Why did Admiral Byrd of the USN take an invasion fleet and 4700 soldiers to Antarctica in 1947, 2 years after the end of WW2?  Look up Operation Highjump.

Why did President Obama visit Antarctica just before his presidency finished?  (unconfirmed)

Why did Buzz Aldrin visit Antarctica just before his death?

Why did Prince Harry,  and Patriarch Kirill of the Eastern Orthodox church visit Antarctica?

Why did John Kerry (US Secretary of State) visit Antarctica on election day?

Why are we not being told what is going on down there?

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Paranoia

I realise that most of you who look at this blog do so to watch the progress on my steam engines, and lately you have been getting a lot of weird stuff about Antarctica.

Well, this is another one about Antarctica.

Suddenly, the Google Earth images of the area of Antarctica which I have found very interesting, have been blotted out with a crude graphic which blots out the items of interest.

The crude graphic looks a bit like cloud cover from a distance, but it does not change over the years timeline and close up it is obviously not real cloud..  Look at the screenshots below, and notice the relation of the graphic to my placemarks, which were inserted by me before the blotting out graphic appeared.

 

Screen Shot 2018-12-12 at 8.42.19 am.png

The blotting out graphic is the two “checkerplate” strips and the area between and nearby.  See how it neatly includes my placemarks.

The “Atmosphere” setting in Google Earth is off.  But it persists in some areas.  And look how it neatly includes all of my placemarks. 

 

Come on guys!  This is beyond coincidence.  Someone does not appreciate my posts about the odd shapes in this region.

Either that, or I am really going a bit pararoid.

 

WTF!

I subscribe to a YouTube site named secureteam10.  It collects many odd videos and photos  mainly about UFO’s and other unexplained phenomena.  A lot is total rubbish, but his post for today caught my eye.

This is a screen shot from today’s secureteam10  post  of a Google Earth view which includes clouds.

Screen Shot 2018-12-11 at 8.18.16 am.png

Notice the straight line cloud (?) between Perth, WA, and Antarctica.

It might be a natural cloud formation, but it does look unusual.

Then I thought, “I reckon that the Antarctic end is somewhere near the area of Antartica where I located the huge reflective black rectangle, and the other scattered odd shapes which I had placemarked”

Well, guess what….

Do you see my yellow and red placemarks?

 

Read this response to Antarctic Weird

I received this email today.  I am posting it with Jennifer Edwards’ permission.  Just reading it made the hairs on my neck stand up!   
BTW, I will continue posting until my current subscription runs out in a couple of months.
John,

sorry to see you go. I was enjoying your wit as well as great machining skills. I have the same issue with a web site I maintain for my partner. The bastids nickel and dime mw to death, send me renewal notices a year in advance, and try to sell me security crap with e-mails spouting fearful phrases that always seem to include the words “haters, Spammers, and internet thieves. I do not blame you for pulling out.

When reading about your Antarctic pictures it reminded me of an experience I had when I was about 18 years old. I have not told this to many people over the years simply because every time I do they look at me like I am crazy, however you seem to have an open mind so I will risk never hearing from you again….
 
The event occurred over forty six years ago. There were three of us present, and unfortunately I am the last surviving member of the group.
 
It was Late October 1972,  the Friday evening before Halloween in Southern New Jersey. My future X, my little brother, and I were on our way from our home town of Cinnaminson to our family cabin on Bamber Lake, in the Southern New Jersey pine lands. I was driving. Our route took us on unimproved two lane back roads that normally only see farm traffic. The weather was a crisp and clear October evening with unlimited visibility.
 
About a mile east of  Vincentown I rounded a bend and there it was in the north west corner of a small rectangular field of maybe three possibly four acres. The road ran the length of the field. The field was surrounded by large old oak trees along the West and the North. The road ran along the south boarder and then curved along the eastern boarder. The field was long and narrow.
 
As I rounded the bend a brilliant light caught my eye. There in the north West corner of the field was a large object hovering. It was shaped like a bell, about 40-50 feet high and maybe 70-80 feet in diameter. Only an oval dome at the top of the bell was above the tree line. 
 
Upon later reflection we realised that the location of the object was less than three miles to McGuire AFB. It would have been a great vantage point to observe the airfield.
 
I noticed that there was a berm along the edge of the field which I drove up on to put my headlights on the object. We sat in awe for maybe 20 seconds at which time the three of us exited the car to get a better look. Please note, to this day whenever I think of that evening the hair stands up on my neck, it was that profound an experience.
 
The object was hovering, maybe ten feet off the ground. It was shaped like a bell with a convex bottom. It was a dirty whitish grayish in colour. The apex had a brilliant white light which radiated beautiful, quickly pulsing, beams of light in pure crystalline colours, vivid blue, violet, red, and green. The beams seemed to come from a brilliant blue white point just below the oval disk on the top of the “bell” to a row of the same colour of white lights evenly spaced along the rim, then from those white spots to another white light in the centre of the convex bottom of the craft.
 
Maybe ten years later I saw my first laser light demonstration, it was that type of pure crystalline single wavelength light that instantly reminded me of that object. In fact the hairs on the back of my neck and on my arms stood straight up.
 
As it hovered it made a sound akin to a very large saw mill blade swinging. I cannot find other words to describe that whirring sound other than a saw mill blade spinning.
 
The three of us were standing in front of the car, headlights on the object just gawking at the objet. This went on for maybe a minute possibly a minute and a half. 
 
BTW I am a licensed pilot and also a highly experienced sea captain, I am a good observer, with an eye for size and distance. We were maybe 175-200 feet away from the object.
 
At that point I alone started walking towards it, my x and brother were too awestruck to move. When I got extremely close, less one hundred feet, probably more like seventy five feet away. The size of this thing sank in. It was the size of a small house! I started smelling that lightning storm ozone odour,  began getting a strong metallic taste in my mouth, and felt tingly on my skin. This scared me so I made a slow retreat back to the car never taking my eyes off the object.
 
When I rejoined the other two we stood there for maybe two more minutes, just looking, listening to the whirring, not speaking beyond a few “wows” and “oh my gods”. Then it hit me, I had a Yashica 35mm camera loaded with asa 400 film and sporting a 200mm lens on the front seat. 
 
I reached into the car, grabbed it and began fumbling trying to remember how to focus  it when you could not see thru the view finder. It was one of those old 35mm cameras with all manual controls. I was unfamiliar with the camera and fumbled around. I never did get a shot, something I truly wish I had done, as anyone I related this story to since that day some forty six years ago has either thought I was crazy or simply humoured me.
 
Any way, as soon as I aimed the camera at the object it seemed to immediately react to the threatening move of pointing what may have been perceived as a weapon at it. 
 
iI’s sound began to change. It got higher and higher and higher in pitch and volume until it was just a deafening hiss, like high pressure steam being vented thru a small aperture. 
 
Some years later in San Diego I had another hair standing up moment when I went to work with a fixed hard disk manufacturer. We had tanks of liquid freon that were huge ultrasonic cleaners used to clean the 18” stainless steel disks before transferring them into the clean room for final assembly. The first time I turned one on and heard that hissss there went the hair standing up again. That was the frequency of the sound. This had to be around 1982.
 
Sorry to digress, any way the sounds frequency went up, the pulsing lights became gradually brighter and more brilliant until the entire craft was one very bright white fuzzy bell. The craft slowly rose to an altitude of maybe 150 feet. It slowly went on paralleling the road heading northeast about 100 feet to the west of the road.
 
We jumped in the car and followed. We were able to keep up with it for maybe a mile and a half  while it slowly accelerated until it finally had a good lead of maybe several hundred yards. It’s altitude was increasing as was its rate of climb. Slowly at first, but obviously steadily accelerating in what settled in at about a 30 or 40 degree climb.. The road ended in a “Tee” intersection. So again we got out of the car and stood in the middle of the itersection watching as it continued its climbing. We were able to keep an eye on it due to the exceptionally clear sky and the fact that we were way out on the country, so light pollution was not a factor..
 
Finally after another five or more likely six minutes the thing was just another one of the stars in the sky. It grew fainter and fainter, until it was indiscernible from all the other stars.
 
At that point we got back in the car and continued on our way.
 
One interesting point is that from the point where that craft was to the runways of McGuire AFB is only a couple of miles. Back in 1972 the area of the jersey pines we were in had many Cold War installations,Nike missile installations, the Space Track “ golf Ball” and others. There had been a nuclear warhead on a missile that had caught fire and contaminated a very large area with plutonium, the active air base was there as well. Plenty to look at if you were interested In the military capability of a civilisation.
 
For the rest of our lives whenever either of the three of us met, right up to the ends of their lives, we always said ” hey remember the flying saucer”. I have only told this story to four or five others over the years. The blank stares or that look like you are some kind of nutter shut me down.
 
Any way there you have it. I wish you luck with your build, and YES please post a video when it is complete, and send me a link.
 
Thanks again,
Jenny

Bye Bye

WordPress has increased their annual fees by another 30%.  under the guise of a “domain name” fee.

Sorry guys and gals, but I am not wearing it.

Thankyou for following.  And a big thank you  for those who have commented or liked my posts.

But I am not forking out another 30% per year, on top of a similar increase a year or so ago.  They are just, fucking, greedy.  too expensive.


.

So bye!    ….John.

p.s.  when the Trevithick dredger engine is running on steam I will post a video on YouTube and maybe Facebook.

pps.  If you want to visit old johnsmachines.com posts, I believe that you will be able to open them by including “wordpress” before the johnsmachines.com

ppps.  if you think that this stinks, don’t tell me.  Tell WordPress.

pppps.  my email is jviggers@iinet.net.au
