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.

Old Pal,

In those 2 location you need to use 3/8 BOM rivets.

A question on the BOM rivets they are of course 3/8 but would they be these? BOM-R12-6 as the length is important since we aren't riveting thick material.

If you have any insight it would be greatly appreciated.

You'll need two different length BOM rivets; one for the frame rail and a different length for the spring mounts. I'll post BOM numbers later today.

I used BOM-12-8 for the 3/8” and mostly BOM-10-4 for the 5/16 except where I had to rivet three layers together at the front spring mounts. There I used BOM-10-6. It’s good to get a little extra just in case because the tool is very expensive to rent. I don’t have enough to do a full frame but I do have extra if you run short.

I was able to get it done. I did get some rivets that did work great. I tested it before I did it to the frame.

so you used a traditional rivet gun ? how did you squeeze the shackle rivets?
could you post a picture of the gun and rivet set you used please?
Niblet:

Here are the tools: 15x rivet gun purchased off of Ebay for a little less than $200, homemade bucking tool, rivet set for gun from Big Flats Rivet Co. (in rivet gun). I already owned an air compressor & oxy-acetylene torch.

Sorry to resurrect an old thread but I'm at the research stage for riveting my frame. I browsed eBay but couldn't find that particular rivet gun. Lots of 3x and 4x guns. Do you by chance have a make or model of your gun that I can chase down?

I have everything and more to rivet your frame
I spent hrs, days and weeks and 500 dollars of my own money to fabricate a suitable bucking bar
I got rivets, dies, you name it
but a 4x gun will work
I had this massive 15× I was using and was bending metal
email me and give me your number I can text/call with some info
