Frame Rivets

so, after two years, i've finally got around to prepping the frame i got from LockDoc (removing manual trans crossmember, and installing C-Notches), and all these rivets are driving me absolutely batty...

basically i've been cutting a X in the head, and then using a hammer and chisel to break the pieces off...

There has to be an easier way to accomplish this task...
any suggestions?

Re: Frame Rivets

That is close to what I do. I drill the middle of the rivet head out, then a few taps with hammer/chisel to remove whats left of head, then hammer/punch to remove rivet.

Take a BFH and a punch he says...



A little closer...



Oh, and here is my dog.



I cut an X into mine, ground them off.. all of them... all of them... all of them... *sigh*

Then punched them out.

I replaced them with Grade 8 bolts, washers, lock washers and nuts.

Good luck man, and where gloves like I should have.

she was tired of holding the punch

seriously though, i've tried using my air chisel, but i don't think my compressor has the capacity nor cfm necessary.

thanks for all the input, and if i never see another rivet it'll be too soon

Re: Frame Rivets

try putting one more line in your X, then use the air chisel. I had to do that a couple of times.

Re: Frame Rivets

I drill about a 1/4" hole and whack it with a chisel and they pop off. also they punch out easy when you relieve them.

Re: Frame Rivets

The best way I have found is to get a GOOD resin fiber disc and angle grinder to grind the heads completely off, somewhere around 24-36 grit. It only takes about 15-20 seconds to grind the entire head off with a good disc. I started off with x-cuts and an air chisel, but this was MUCH easier to do.

Then I used an air hammer with a punch to drive the rivets out. This works probably 90% of the time, but occasionally you'll need a monster hammer and punch to get some stubborn ones out instead of the air hammer.
