Swivel gun recoil--need help

[Canute Rex]

Greytop, I agree with Wheelock Wohl.

Add a long back leg at a shallow angle from the top of the post to the ground. Put a rod/plate/timber from the lower/back end of that leg to the bottom of the post to make a triangle.

Add a cross piece to the lower/back end of the back leg, maybe two or three feet wide. The leg would be a T.

Attach a piece of angle iron to the bottom back edge of the cross piece so it will dig into the ground.

This way, when you fire the gun, the rearward force will be transferred upward, but at a mechanical disadvantage. The recoil will be trying to lift the gun up on the end of a long T leg. The cross piece will spread the force across more ground so it digs in instead of cutting a groove in the dirt. It also prevents the whole assembly from tipping sideways.

Good luck and have fun!

Interesting solution. I think I'll give it a try and let you know how it works. Thanks

Doesn't that relegate the post to merely supporting the weight of the gun?

Set the post into the ground, put the strut half way up and it will take it's share of the recoil :thumbsup:

Is 500 grains the minimum powder charge for your club competition?

Poor Private, you lead an interesting life, firing swivel guns out of steam trains and passenger cars!

:hatsoff:

Nice gun and mount, My 2" gun is mounted on a wheeled carriage, I use only 300 grs of cannon powder and it recoils pretty good, the barrel weight is 120 lbs. I have used as low as 150 grs of powder, I think part of your problem is too much powder, with 500 grs I can hit targets at 600 yards, swivel guns were made for close range use so less powder should work better. just my opinion.
