George the Third.

by John

In 2015 or thereabouts I was persuaded by Stuart Tankard to get into CNC machining. So I bought a second hand Seig lathe which had been converted to CNC. The Seig was really a waste of money. Too small, too inaccurate, too flimsy. And the conversion, I gradually realised, had been done with the cheapest possible components. But it did awaken a world of possibilities. I made some simple shapes…. spheres, tapers,etc, and I started searching for a better machine.

I had offered to buy Stuart’s Boxford TCL127. Not suprisingly he declined. But he did know where there was an identical one which might be for sale. Long story short, it was available and I bought it.

Now, what to make first?

Hmm…. what about a cannon? I had no interest in cannons, but the shape seemed suitable, so I did turn a long gun barrel, and that was fine, but the Boxford has one major limitation. The maximum size object it will handle is 127mm long, and 127mm diameter. So my cannon barrel was a bit pathetically small.

I showed the barrel to my model engineering club, and Bob, a senior member, offered me the use of his CNC lathe. So in 2016, I made a 24 pounder 1779 naval long gun, scale model about 300mm long. It turned out quite nicely, and I became very interested in the history of cannons as well as the machining aspects. Then I made a 32 pounder carronade circa 1805, at the same scale. And then an1866 rifled muzzle loader 80 pounder, and a 110 pounder rifled breech loader, and a1465 Ottoman bombard, and possibly more to come. None of these, I must mention, are capable of being fired.

But back to the long gun and the carronade. They were finished, as far as I was concerned, except for the cyphers on the barrels. Royal Navy guns which were made for HM ships always had (as far as I know), a moulded or carved cypher of the reigning monarch. The British monarch in 1779 and 1805 was George the third.

Summer has finally arrived in Southern Australia. 33 centigrade yesterday, and 40+ today. Too hot for the workshop, but not for Stuart T’s 30 watt fiber laser.

The 24pr 1779 naval long gun, with King George 3 cypher, expertly lasered by Stuart T.
The 1805 Carronade with its George 3 cypher.
The cypher is 22mm x 10mm. The lasering took about 2 minutes, after fiddling with the positioning and focusing and settings, and a test run on some scrap. Can’t remember where I found the image. The close up photo shows my substandard finish turning, as well as the superb result from Stuart’s lasering. After lasering, the lasered cypher is blown with compressed air to clear dust from the grooves, then a rub with 1200 grit emery paper, then some Brasso.

“GR” George Rex.
