just wanted to share with you all my homemade BP salute cannon. Whole thing was built in my shed over the course of a week.
not sure if I can post a finished pic in the forum- but will happily email a pic and info to you
going off memory (cause it's not in front of me)
the barrel is surgical stainless, about 16" long with a 1" bore- threaded in the rear with a plug (oh the jokes
) for easy cleaning. The side plates were cut with a jig saw from aluminum stock- the wheels were cut from the same stock using a hole saw. Counter sunk and tapered the holes best I could with a 50 year old drill press and used brass fasteners to hold it all together.
I use about 25-30 grams of fff BP packed with newspaper- it echo's for a good 5 seconds after a blast and really pounds the chest.
everyone who hears this thing wants one-
