Black Powder Cannon

load with too much powder on that thing and you'll go backwards  :scratch:

Andrew,

A little bit of recoil is taken up in the stretching of the breeching ropes, but the great majority does just as you suggest; send the punt backwards. Obviously there are lots of variables but the principle of every reaction having an equal and opposite reaction is well presented in gun recoil. I've seen punts go back four feet with a good load up he spout; Isaac Newton is alive and well living somewhere on the Medway.

The entire thread runs to 50 web forum pages, but it's both fascinating and inspiring. Terrific design skills and craftsmanship together with a very understanding 'Er Indraws.

BronxFigs:
Thank you for the interest.

Gathering material, bar-stock, tooling, etc. for the project.  I decided to turn a "mock" barrel from wood, just to check carriage proportions, barrel dimensions, etc.
