Don't know for sure but he is probably using an old Shoe Last Duplicating Lathe. The youtube shows an old one being used. It shows the duplicator in the first part of the video. The rest of the video is irrelevant.It's elm. It was a double stem, and there is a seam with inclusion pretty close to the middle. I'll probably clean it off a bit with the hose and then cut from the middle out on each side as I could probably move half of it "pretty easily" in comparison to the hole thing lol.
I was talking to a guy at church tonight and he said a friend of his has a machine that makes stocks. He sold him walnut trees that were hollow and the guy would use the crotch wood and leave the rest, then he would make firewood out of it. I never knew there was a machine like that an individual could buy.
I had a friend years ago that used one to make wooden duck decoys. He has passed and I have often wondered what happened to the lathe. I'll try and post a pic of one of the decoys the lathe produced. The same could be done with a gun stock.
