Recoil Question

Unread postAuthor: Atlantis » Fri May 12, 2006 10:26 pm

Not really recoil but...I was wondering if I used Galfisk's pump-action design and used the force acting on the ammo to slide the bolt forward and have a spring push it back. If it is enough force, you could use it for an automatic bolt for spudshells. I was thinking of just taking a standard cannon, put a slot in the barrel for the ammo to drop into, and let the recoil of the gun pull the bolt and a spring to push it back into place. I thought about this while reading about the .50 caliber Barret Rifle with the "floating barrel."

The barett and spudgunning meet once again...

Regarding your idea, what sort of ammo is this meant to use to provide such a massive recoil, remember guns that use recoil to load the next shot fire big, heavy bullet.

Other than that its a god idea and certain people on this forum do have the required skills to make this.

By the way, there are 3 <b>full</b>-auto combustion launchers in the design and assembling phase right now. I am doing one of them.

thats a pretty neat idea. you should look into this a bit more and create a theory for semi-auto spud guns. :)

I think - because of the relatively small projectile mass - you'd be better off using the gas system instead of long recoil (i.e. Kalashnikov instead of Desert Eagle). You'd need a lot of pressure by spudgun standards, though. Look into how real guns work. The designs have been around for a century.

I've seen that design, it has too many electrical components for me.
Here's Galfisk's design, http://www.spudfiles.com/forums/viewtopic.php?t=261.

For my idea, reverse the layout and have it push the ammo forward under spring pressure, the gun will fire, the ammo will exit, and the recoil will force the bolt back ejecting the shell, on its way back the next shell will move into the now empty slot, the gun is now ready to fire again. The user would have to hold the gun by the tube that the bolt is in to allow the gun to slide back. If you took Clide's semi-auto design and built a mechanism so you could still pull the slide back from the trigger on the tube. This could make a working semi-auto spudshell loaded gun.

I'll draw up some ideas.

Cool, I thought I was the only one with a semi-auto combustion. Do you have any pictures up of yours?

Do you now? So by the flip of a switch, everything is activated?

The Proton Pack has been pretty practical so far. I'm not sure what you mean by that. It can also easily be rebuilt to be specifically functional as a handheld auto GB gun.
