This shows the cannon in progress. The breech end has been roughed out,and is about ready for the final contouring and polishing.

You can see from the chips how tough this material was to cut.

Note that the trunnions are below the centerline on 18th.C. cannon.

There is a separate ring of brass around the muzzle to keep the chuck jaws from damaging the cannon. A small teat was left on the breech end,sticking out from the cascabel knob,which can be sawn off so there is no center hole in the finished breech.

The color of the metal is beautiful. The lathe is a 19" swing Promaster,80" between centers. It was called a 17"X80",but would actually swing 19". First time I ever saw a lathe's capacity UNDER stated!

You can just make out part of the tracing templet for the breech of the gun. Then,the cascabel knob is a separate template.

For many years I have had a little manual Lehigh(sp?) tracing unit. It uses a linear ball bearing in its tool post to trace a maximum of 1 1/2" So,for large projects like this,I had to make separate templates for large areas.

The tracing unit is off the lathe for this picture. I only ever saw 2 of them,and bought the other one for Jon. Used the tracer a lot when I was making the spinning chucks for the PGA trophies.

Monarch always understated their lathes. 10EE, rated 10", actual 12.5 to 12.75. Series 60 rated around 16 and swung 18.
