A modification to the Radius Master

The Radius Master is a quality 48″ x 2″ belt sander which is impressively versatile with its 7 work stations.

The work station which is vertical, and against a platten is the one which I expect to use most often.

Vertical belt, and using the backing platten.

But the supplied work – tool rest is a bit narrow for my taste, and I decided to make another one.

I really like the one which was supplied with the Acute Tool Sharpening System (ATSS).

The Acute Tool Sharpening System from Eccentric Engineering.

So I bought some 4mm steel plate and cut it to size (150 x 150mm), and CNC milled a support bracket to fit the Radius Master.

The rest is adjustable for angle and distance from the belt.  Copied from the original.  The bracket is screwed to the plate.  I did not want to risk heat distortion by welding the join.

Then the penny dropped.

Why not use all of the ATSS fittings and fixtures on the Radius Master?  So that is what I have done.

The ATSS system looks quite at home, yes?

Hey Gary Sneezby, maybe you should do a deal with Radius Master.

I can quickly swap the ATSS fittings and fixtures between the CBN grinding wheel and the Radius Master.  It will be interesting to see whether the cubic boron nitride wheel or the belt is preferred for different applications.  I expect that the belt will be best for quick removal of material and the CBN wheel for tool sharpening, but we will see.

Oh, and by the way, the bigger work plate does not interfere with any of the other work stations.

And I will ask my friend Stuart to laser engrave some guide lines on the plate.  I have a new design to try.

And finally, here is a link to the video of using the ATSS, by Eccentric Engineering.  It is worth considering.  If you have not done so, I suggest that you look at Eccentric Engineering’s other tools too.  They are very interesting.  The lathe parting tool is the best one which I have used.  And the Diamond lathe tool gets more use on my lathe than any other.

 

 

 

ACUTE TOOL SHARPENING at GEELONG MODEL ENGINEERS’ EXHIBITION

One of the tool displays at our exhibition last weekend (see previous post) was by ECCENTRIC ENGINEERING.  Eccentric Engineering is well known for the Diamond Tool Holder, which is a favourite lathe tool holder for most of us who use metal working lathes.

However I was more interested in Gary Sneezby’s (Owner-engineer of Eccentric) new tool, which is a tool sharpening system for use with a bench grinder, named “The Acute Tool Sharpening System”.

The Plans and assembly diagrams, in a bound booklet.

The system is available as a complete working unit, or a kit of semi machined parts and plans, or plans only.

See the Eccentric Engineering Website for a complete description of the system and prices.  eccentricengineering.com.au

I bought the kit of semi machined parts, and the booklet of plans.  Cost (show price, no postage) $AUD250.  This is an excellent price for the 50 or so laser cut parts, quality die cast handles, all fasteners, Allen keys, detailed plans.

2 of the 33 pages of plans and diagrams.

The plans are excellent.  They are clear, easily read, and large.  There are no instructions, but a DVD is planned.  Gary is contactable by phone for construction advice, if needed.

After 4 half day workshop sessions I am well into the construction.  The laser cut parts are accurate within 1mm, and drilling points are accurately centre drilled.  Gary pointed out that the drilling points are more accurately positioned than the laser cut part perimeters.  That necessitates drilling centre holes (and the other holes) and using a mandrel to enable accurate turning of circular components.  He also advised that HSS cutters be used in preference to carbide tipped tools.

I found the parts to be very closely dimensioned to the finished parts.  The table top measures 150x150mm, and I found the flat hardened steel to be mildly bowed, to the extent of 0.38mm.  That is probably due to heat distortion from the laser cutter.      Some attention on the press straightened out the plate to less than 0.05mm bowing.   I might touch it up on the surface grinder, but that is probably unnecessary, given the way the system functions.

I had a machining accident with one part.  It is useable, but will need to be replaced.  I rang Gary, and the new part is in the mail.  Now that is service.

Progress to date….

The sharpening system is starting to look serious.  It consists of a base, top plate which is adjustable for tilt and height, parallelogram arm, slide and toolholder.

It looks interesting. Not sure how it works yet (Much clearer since watching the YouTube video at the end of this blog). Still some parts to be made-machined. The notch at the top is where the grinding wheel fits.

The underside. Nice use of O rings to lock the adjustments into position. The cast handles are good quality.

 

Another session or two in the workshop should see this project completed.  I will report on how it performs  in a week or two.  I expect that it will be a lot quicker and simpler to use than the Quorn.

Watch the YouTube video by Gary to see how it works.
