Final Lasering on Armstrong RML model cannon

The lettering on the muzzle reads “Marshall’s Iron”. It refers to the steel bore of the barrel, which was supplied to the Royal Gun Factory by a specialist manufacturer, Marshall Iron. The rest of the barrel was made from wrought iron, as a coil, as described in a previous post.

Stuart operating the fibre laser, and Jamie who runs Stuart.

The barrel is 300mm long, too high for the laser machine to focus. So the setup used a low profile 3 jaw vice, hanging out from the edge of the machine, with the breech of the barrel down the front of the desk/bench.

Immediately after lasering, which took about 20 seconds, (and about 45 minutes to set up the machine/supports). The circle represents the junction between the steel bore and the outer iron coil. The vertical line was used for sighting.

The lines and lettering looked a lot sharper after a quick rub with emery paper. Those letters are less than 1mm high. A very magnified, not well focussed photo.

The cannon is now mounted on a shiny acrylic/wood base. It reflects the underneath details. And has handles.

Thanks once again to Stuart Tankard, for using his fibre laser machine to accomplish the engraving. Stuart told me that he has done more jobs for me than he has done for himself. I call it “getting experience”.

And, WordPress has now improved its program to the point that captions cannot be added to photographs, and a title cannot be added to the post. Well done WordPress. (p.s. 16 June… captions and headings have reappeared. Hooray!)

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.
