As I was in the middle of making a taper turning attachment for my 10x20 lathe in order to make a cannon barrel, I realized I could only make a straight taper. Could you make a profile template and attached to the taper jig. How does one make the decorative finials ,rings etc. I was going to make a 8-10 inch barrel for a old style navel gun or civil war type.

You might check out this video


from DiResta where he makes a cannon. He actually free hands the curves and tapers, dialing both handles at the same time.

OxToolco also demonstrates a profiling technic on one of the Baby Bullet video's in that series. His method is a little (or a lot) more accurate as he uses a profile template and dial indicator to help in following the profile.


Since it's your cannon you can decide how much accuracy you need and pick your poison.

The easiest way to do the detail work is to use gravers, in my experience.

I may try making a Parrott cannon as my first but its hard to find plans that you don't have to pay for.

I believe that the reinforcing rings on the parrott rifles were put on hot and shrunk in place.
