Sometime over the winter Grandpa decided he wanted another, and built a 1/2 size Napoleonic cannon. He did everything but actually forge the cannon and wheels. He has to make his own loads (two pounds, I"m told). Bear in mind I like firearms but I'm not "into" them, so my info might be innaccurate.
Anyway, Auntie was on hand for the first official firing. This is also her first ever video edit.
