Just picked up a few in 69 cal. Finished the wood in BLO and cold blued the barrels.
Going to be fun to get out and shoot.

What you think?

I think you need to send them to me for closer inspection and proof testing

the Address is ........

They look good! hope you get years of enjoyment out of them!

Thanks,

Got one more that should be in the works in 75 cal.

Talked to him about a 1" but don't know if I could hold onto it....

I took the cross pin out and added a dowel pin, think it looks better. I used a little glue, but it will still come out if needed. Was going to do a rivet but I would not be able to pull it down if needed.

Nice! Always good to have some more handgonners around!

Victor3 · « **Reply #4 on:** July 26, 2010, 09:51:26 PM »

Those look great.

I think with a lead ball, anything over ~70 cal might be less than pleasant to fire in a handgonne without a muzzle brake.

A muzzle brake on a handgonne?

Medieval tacticool!

Those are cool . I cant wait to here how they shoot .

If you figure it out ........let me know , I mean no kidding these things are as unorthadox to shoot as any bottle rocket launcher you ever cobbles together as a kid ....only not as accurate .

THE NEXT time we go ashooting I will leave everything else at home . (mostly) and take only Morko .

IF a body 'can learn it ,I would like to . Plus 50 grains will be about my starting load , as if these thingamoroos are supposed to have penetrated armor ........ ?

Personaly I'd would have aimmed at the horses . Yep , bring men at arms down and finish them ..... or ransom them but killing the horses would be mission #1 in my book .

Some calvery get off their mounts willingly like ..... like the fools at the Little Big Horn (JMHO) having been there and studying that battle for years . "

Some may need to be knocked off their horses by ........well anyhow you could . A ball to the horse should do it .

I think you'll need a decent grip to keep it from recoiling backwards .

I think a one inch bore with a chamber will work ok if it has a hook on the bottom. Maybe about a 5/8" diameter powder chamber. I'll build one for myself and try it.

If it works make me a deal and I will be shooting one also

Good ideer. Thataway you can latch the hook on the window frame of yer peekup truck door to shoot it.

I think shooting a 1 inch handgonne will be interesting. very interest. Dom be sure to take video.

dominick · « **Reply #11 on:** July 28, 2010, 03:34:16 PM »

A few years back a GBO member built a 1" gonne. Can't remember his name. Here's a link to one on Youtube. http://www.youtube.com/watch?v=ZpoyN2L3ol0

1.5" bore - from Claypipe, I think:

Cat Whisperer · « **Reply #13 on:** July 29, 2010, 06:06:00 AM »

I made one in golf-ball caliber. (I would NOT try it with steel 1.7" spheres.)

Double D · « **Reply #14 on:** July 29, 2010, 06:08:59 AM »

If you haven't noticed, but Tim's References sticky at the top of the board has a bunch links to handgonnes sites.

dominick · « **Reply #15 on:** July 29, 2010, 10:07:30 AM »

No, wasn't Claypipe's although that's a large caliber without a hook. The guy's from Texas I'm thinking of. Would be inteested to see what he shot in it. Charge and ball weight.

Victor3 · « **Reply #16 on:** July 29, 2010, 11:58:21 PM »

I'd be concerned about the safety of firing a 1" or larger handgonne with a ball. Seems like it could have the potential to be like a premature ignition while holding the rammmer, just in reverse. $:-\$

GGaskill · « **Reply #17 on:** August 05, 2010, 03:31:37 PM »

A 1" steel ball weighs about 2.3 oz and a 1" lead ball weighs about 3.4 oz. The barrel might weigh a couple of pounds plus a similar amount for the shaft. Gonne to shot weight ratios are 28.8 and 18.8 to 1. Velocities are in proportion to momentum. Obviously velocity is dependent upon powder charge.

This is a 1" steel ball fired from a 48 lb barrel:

George,

What would you conclude, considering the data you presented?

Would the recoil produced by a 1" handgonne loaded with a ball (lead or steel) and a reasonable charge be safe to handle by the average person?

Having fired a 4 bore single shot rifle that weighed some where around 25 plus pounds I can tell you that I have no desire to fire one on the end of a stick.

That's one reason I got into cannons. I like big bores but don't like firing guns that have them when they're attached to me.

Crew served is the only way to go .

GGaskill · « **Reply #22 on:** August 07, 2010, 08:19:58 PM »

What would you conclude, considering the data you presented?

Just for the record, I weighed my .50 cal gonne and it weighed 5 lb 3 oz complete, about 25% heavier than the guessed weight above. So a 1" bore gonne would weigh more than that, perhaps as much as 7 lbs (112 oz.) That gives a weight ratio of almost 50:1 so a ball at 500 ft/sec would give a recoil velocity of 10 ft/sec and a recoil energy of about 11 ft-lbs. Since the gonne would likely slide through your hands instead of recoil like a .44 magnum, it probably wouldn't be a big deal.

But I would wear gloves when firing it.

Does this mean that if the opportunity arose to fire an FIM-92 Stinger at a hydrogen filled Zeppelin (unmanned target of course) that you'd decline the offer?

You're aware that HIND (Soviet helicopter) is not short for HINDenburg, right?

George,

If I'm reading right, you're calculating for a steel ball. Isn't 500 fps a little low? What charge would give that velocity?

dominick · « **Reply #27 on:** August 08, 2010, 03:50:30 AM »

If you have a hook on the gonne or mount it to a stand, recoil would not be an issue. Here's another video of a 1" bore. http://www.youtube.com/watch?v=1V35ELa_h4Y

gulfcoastblackpowder · « **Reply #28 on:** August 08, 2010, 05:21:40 AM »

My least favorite thing about shooting cannon is not feeling the recoil directly. Of course, the shockwave hitting you from a cannon can be quite enjoyable, though. I love shooting firearms with heavy recoil. Sure, it may make it harder to hit you're target, but for me it's great fun!

Hey, take it easy, I think these jokers are now (at least in some circles) regarded as a kind of ally.
