I tried to weigh the pros and cons of continuing or abandoning the project altogether. In the end I decided that instead of making a barrel for rum or brandy, I could make it for dog treats. Since they are not liquid, the barrel will work for that.
I had made a couple of ends/bottoms for the barrel out of spruce, and these were made into octagonals to fit the inside.
The hoops are made out of a piece of copper tube that was split down the middle using a hacksaw. After splitting , it was flattened on an anvil by means of a hammer. The hoop was riveted together using small pieces of copper wire from an old electrical cable as rivets.
Each hoop received a total of six rivets. five to hold the hoop together and one rivet for holding the eye that will allow the barrel to be attached to the collar of Bertha.
I had measured each hoop directly from the barrel, in such a way that it was a bit too small so I could rely on it to be stretched a bit and gain a good tight fit.
The hoop was first negotiated into place by tapping with a hammer on top of a piece of wood. Once it was level with the edge of the barrel, I switched to a drift wedge. A regular piece of flat bar would have worked equally well, but this was just at hand and had a perfect size for the job.
Normally I think the hoops are expected to stay put without any fixations, but I didn't want to take that risk with this project. I made four small rivets and attached each hoop with two of them.
Finally I sawed of the ends of the barrel down to the edge of the hoops and sanded the outside flush.
I didn't drill a hole for the dog treats yet, because I think a Forstner bit will be better than a regular metal drill bit like those we have out here. So I'll do that once I get home.
The barrel ended up being 6" high and 3 3/8" in diameter at the middle.
