So for my next build, I would like to add an aesthetic recoil system, that makes the cannon look like its firing alot harder than it really is. Any ideas on what I could do to do that? I was thinking some sort of sled on springs, and when you pull the string to fire, it slams back and then pulled back up. Any other ideas that may work?
I'd just make a normal, 'weak' recoil system, then make everything on the gun as light as possible. Use the heaviest projectile you can.
Long ago I was shooting lead slugs from a combustion, which weighed only six times more than the slugs. The recoiled from this was very significant, since I was absorbing ~1/6th of the gun's muzzle energy (equal and opposite reaction/conservation of momentum).
The nitro-express has such a massive kick because there's not as much difference between the projectile's mass and the gun's mass. A .50 cal rifle with a recoil absorber can be shouldered without too much effort, since it's heavy.
Well, this is no where near hand held... Its going to be a 3" or so bore, and 7' long barrel. Going for a howitzer look. This is going to a milsim team, JROTC for that matter, around here, and they want it as close to the real thing as possible. Launching the average nerfs, possible howlers since they make a huge amount of noise. I was thinking a big 3" ball or butterfly valve, for max airflow with it being as close to real as possible (the pulling on the string part at least...) and that dumps the entire chamber right into the barrel. It would be inline, so no reason for the air flow to be blocked or choked or anything. I need it to recoil as much as possible though.
