Thank you. I designed the tool and had a friend with a full machine shop make it for me.

It is self-contained - no other clamps required. Insert rivet from inside the frame, place the tool into the c-channel and put the rivet head in the recess on the tool and hand tighten. Once the rivet head is in place, the tool will stay in place so you just tighten with a ratchet and allen driver. With everything tight on the inside, make sure the gusset/shackle is clamped to the frame tight. Heat rivet to welding temp (white hot & even sparking with neutral flame) and hit it with the rivet gun for 2-4 seconds. You will get a mushroom. Reheat and repeat. By the 4th heating, you should be very close. I used a piece of shim stock to make sure the rivet was formed all the way to the frame and called it a day. Just be careful as the bucking tool is a lot of steel and works as a great heat sink - it is extremely hot after bucking a rivet!

As I mentioned in the PM, I am talking to some local machine shops to get a few of these made for other sick souls. ;-) One other thing is I am going to get the Big Flats rivet set remade to match the Willys rivet. I may get ambitious enough to get a Ford style made as well.

Regards, Patrick

Nice work and nice results!!!!

I don't want to go too far off on a tangent here, but.......I was looking at my passenger seat frames and noticed that some are riveted at the hinge and others are bolted. I even have one seat frame where one hinge is bolted and the other has a rivet. I can only assume that rivets were original and when they wore out they were replaced with bolts, but I'm not sure. Is this another rivet application that many of us overlook?

Patrick, did you ever get any of the bucking tools made? I am almost ready to rivet myself

Commercial portable rivet press.

I wonder if this could be adapted. I don't know the dimensions or the capacity.
