Here is a picture of what that Gonne I have up for auction looks like with a tiller. I made three tillers this weekend. My vote for the best ever use for a shovel handle :-D :-D Overall legnth is about 50 inches. I can drill a hole for a screw or pin if needed. I had planned on epoxy though.

Here is a link for that auction. If the winner wants me to build a tiller. They will be $30 extra.

What would be the best way to attach the tiller to the Gonne? I had planned on epoxy but it might be better to pin it or drill it for a screw? Ideas would be helpfull.

Thanks, Wes

Hey Powderkeg, I would drill it for Pin or screws, I've used epoxy for years on model airplanes (the ones that really fly) What I've found out was that gluing wood to wood works great, wood to metal is not so good. Over time from handling and shooting the epoxy would seperate from the metal. By the way nice work!

Maybe a really coarse thread so the wood is pulled into the socket, then a screw to keep it from unscrewing.

If you are going with historical accuracy I would use is a pin all the way though and peen over on the ends. IÂ’m not sure if this is what they used or not but it seams logical to me. I was going to use this on my first gonne but I got anxious to fire it so I used screws. I found it much easer to clean if it could be taken apart so I left it that way. If you were to use epoxy I would make a series of ridges in the socket with an internal threading tool. There is no need to take the time to actually thread it. The ridges should fill with epoxy locking the tiller in place.

Powder Keg,

I finally had a chance to pick up the gonne from the post office this morning (it was very nicely packed by the way). I tried it out as soon as I got home. It shoots great! I began with 50 grains of Fg and bumped it up in 5gr increments to 70 grains. I was surprised by the very light recoil, considering this thing shoots 550 grain round balls. I had an absolute blast!

I want to compliment you on your craftsmanship. The gonne is a beauty. The tung oil finish on the tiller came out fantastic. The screw attachment works great and made clean up a 3 minute job.

IÂ’m taking it up to my brotherÂ’s range in Michigan next weekend. The recoil is so light you can comfortably sight straight down the tiller and barrel. IÂ’m pretty confident I can hit paper at 25 yards. IÂ’ll post results.

HereÂ’s an action picture from this morningÂ’s shooting. I simply sat the gonne on the end on my deck and weighted the tiller down with a couple of bags of shot. It didnÂ’t move at all from recoil.

Thanks again for a terrific gonne. I really feel fortunate I won this auction.

I do have a question for any knowledgeable gonner on the board. What should be considered the maximum safe load of Fg for this .75 cal gonne? IÂ’m using .715 inch round balls and 0.15Â” patches.

Hi,

I'm glad you like your new Gonne. Recomended loads for a .75 cal barrel with ball are 70 grains of powder. I've shot more, but I won't say how much. Please remember to be safe. Thanks for taking the time to take pictures and post them and the compliments.

Thanks, Wes

We shot 22 balls out of this gonne at a remote range in Michigan last week. Best results were obtained by holding the gonne chest high. This stance puts the eye about a foot above bore axis, but we were able to consistently hit a 3 foot by 2 foot target at 25 yards. I tended to shoot low and to the left of "point of aim" , but most of my impacts were within a 15" circle.

The range's shooting bench area is elevated a few feet, so we were shooting slighltly downward towards the target. When those big .715 balls hit the ground behind the 25 yard target they bounced off the ground and ended up at the base of a big dirt berm behind the 100 yard targets. Recovered balls slowed very little damage and could have been shot again in an emergency. Fortunately there were no medieval mercenaries in the immedite area and the used balls ended up in my brother's casting pot.
