Here are the three styles I have built:

Each one is about 13" long and made from 1.5" 1018. The first two are 11/16" bore, the bottom one is 33/64" bore.

Whatever happened to this project?

I am still interested in obtaining one of these.

Ed -

These can be simple or complex to build. Why not build one for the contest? Settle on the design, and I've got (see current contest posting) some pieces of stainless that would make a great handgonne. You could contract with one of our sponsors or someone local to you to make it - if it's round and has no tapers it is very straightforward and simple. Faceted sides and tapers are easy if it's cast but lend more difficulties (more complex setup times and machining) if it's machined.

Well, I am a collector of medieval and renaissance arms and armor primarily so that if I add a repro to my collection I would like it to be as accurate as possible. That said, I have been known to send various projectiles downrange when the mood strike me.

Here is a photo of a 1:1 repro of the Lusholt Gun that I picked up along with it's presumed projectile.

This forum is marked as dead,

. Sad. because I really wanted to tap into the subject! I'm making a 12 inch, 1.5 wide gonne, 1080 steel, .50 cal, with a .30 cal powder chamber. 1/4 inch touch hole. no tapers, nothing, pure round. Anybody who's still reading, thoughts?

You mean the thread is marked as dead? Because the forum certainly is not. True, "handgonnes" have not been at the forefront of discussion recently, but we still have them. I would not make a 1/4" vent with a .30" chamber as most of your charge will go out the vent instead of down the bore. In fact, I wouldn't even bother to chamber a piece with a .50" bore.

1080 is a little much but it should be OK as long as it is not too hard/brittle.

1018 ? Much better, less brittle.

Welcome. A big interest of mine. We'll come out of the woodwork.

I'm playing with ideas. I am either doing a straight hexed piece, with a little filing, to cannon the barrel. or a straight round piece. how big should the touch hole be?

Touch hole - about 1-1/2x diamter of the fuse. Use the smallest fuse available to minimize losses through the vent.

and WELCOME to the board!

I'm glad to be welcomed. so the punk sticks i have to ignite are 3mm in diameter, so the touch hole should be 2mm? or so? I want some sort of chamber... I'm not sure what tho.. Because i'm not going to file, or do anything fancy. (i might add a flare) aside from general machining, it's just a pipe on a pole.

Cat Whisperer · « **Reply #101 on:** February 02, 2011, 10:34:44 AM »

cannon on a stick is the term I use.

I'll post more later tonight on design, you're likely to get more responses inbetween ....

dan610324 · « **Reply #102 on:** February 02, 2011, 10:49:53 AM »

if you are able to put a 3 mm fuse in a 2 mm hole you have done a good job , so please try and report here .

I would try to find a 1 mm or 1,4 mm fuse for a 30 cal chamber
and use a 1,3 mm or 1,7 mm drill

GGaskill · « **Reply #103 on:** February 02, 2011, 10:50:10 AM »

I had heard of them as "pole guns" long before hearing of "handgonnes."

Cat Whisperer · « **Reply #104 on:** February 02, 2011, 03:49:28 PM »

OK, do you need a powder chamber?

The metal all around the are where the chamber is, should be as thick as the diameter. This makes a 3" diameter tube for a 1" bore and a good inch of metal behind the end of the bore.

OK, lets build it of 2" stock with a 1" bore (a bit heavy). You would need a powder chamber that is 1/3 the diameter of the 2", like 0.67" in diameter to give you the right thickness of metal.

Look in the reference stickies - there are all the rules of thumb and a number of links to the historical development of powder chambers too.

aapch1 · « **Reply #105 on:** February 03, 2011, 05:58:02 AM »

The piece i decided on is 1.5" wide, .560 caliber, and the powder chamber is .240, and only 2" deep, I think that will do the trick, but, again, I'm not sure. I think once I have it finished, I'll put several blanks through it, and see just HOW well it really fires. the piece in all is only 8 inches (modeled slightly off of the danzig model, internally, and size, just modified) Thoughts on the piece? (i should have pictures in a week or so)

Longer thinner powder chambers produce higher pressure focused on the middle of the round being shot, compared to larger diameter shorter powder chambers.

GGaskill · « **Reply #107 on:** February 03, 2011, 08:29:47 AM »

... and the powder chamber is .240, and only 2" deep ...

With a diameter that small, you will lose a lot of pressure out the vent. If you are not concerned with range and power, it won't matter. But if you are, you will need a small vent or a larger chamber diameter.

these are just ideas..idk what im going to do... especially since my machinist isnt getting back with me... i dont have a drill press.. and its gonna be expensive to ship to him, and then pay for labor, and ship back.. i might make the chamber longer....not sure... if he ever gets back with me....

Welcome aapch1 , I'm sure a sponser could make you one , Dom always comes to mind with these projects . (no matter what they are

)

They are a hoot to mess around with .
Here is one I made

This is a pic Dan took in the Stockholm Military museum ,it shows the origanal (circa 1350) with a repo I sent to Dan8)

Here is my Moko with a wild cherry shaft .

More like aiming a bow and arrow than a gun .

So what should I do then? any recomendations?

Rocklock, I'm digging the gonne

hehe, bet it fires wonderfully. how much would it cost for me to get a sponsor to make me one?

GGaskill · « **Reply #113 on:** February 03, 2011, 03:00:56 PM »

My recommendation would be to go .56 cal the whole bore. You don't "need" a separate powder chamber, that is just how they did it. Now if you want a powder chamber, I would go no smaller than 7/16 for a .56 cal bore.

Are you going to fire with loose powder in the vent or with fuse? Loose powder would allow a smaller vent but it can be more of a pain. However, fuse introduces a delay that can allow undesirable things to happen (like some fool running in front of your gonne) before it fires. Everything has its consequences.

But you have to make your own decisions.

RocklockI · « **Reply #114 on:** February 03, 2011, 03:01:11 PM »

I made it but I am not a sponser . How much will be between you and the sponser ,see stickies .

Good luck , this is a great place to learn !

aapch1 · « **Reply #115 on:** February 03, 2011, 03:56:13 PM »

I guess I really don't need the powder chamber, i was thinking vent. Fuses have never sat well with me. delayed fire is EVIL. the reason I wanted the chamber, was for more of an "oomf". But seeing as i'm kinda young, i have no clue what i'm doing. I got back with my machinist, he's limited on drill sizes, thats another reason why the chamber was a good idea.. or so i thought, I'll see if he has a 7/16 bit.

Cat Whisperer · « **Reply #116 on:** February 03, 2011, 04:23:33 PM »

Here's one I did in 1018. Is about 10" long, 90 caliber (shoots 3/4" copper tubing sections). Powder chamber is about 1/2" in diameter.

The gray stuff is a potting compound used to fill the volume inside a motor that is used in wet environments. When we fill a batch of motors (draw a vacuum on each to help get rid of the air pockets) there is always a cup or two of the two-part mix left over. I have a few odd pieces of tubing filled with what would otherwise be thrown out.
