Rivit Removal!

I know you could check the link on bucknbronc's latest post yourself but I just got done reading this one and feel it is totally appropriate, Those who are in line to do a suspension lift take note! [img]images/graemlins/grin.gif[/img] Those who have been there will find this hillarious: <font color="blue">Erik's Rivet Removal - Level #101
Method One
Air chisel each rivet head @ 30sec per rivet
Change bit to blunt nose punch @ 60 sec
Punch out rivet body @ 3~5 sec per rivet
Method Two
Center punch rivet @ 2 sec each
Drill each rivet with 1/8 bit @ 90 sec each
Drill rivet with 3/16 bit @ 30 sec each
Drill rivet with 1/4 bit @ 30 sec each
Drill rivet with 5/16 bit @ 30 sec each
Drill rivet with 3/8 bit @ 30 sec each
Drill rivet with final dia bit head should now be off, small dimple in the body of the rivet
Use cold chisel on the three rivet heads you did not center punch in the center, so hole was off center, head is still on @ 5min each rivet
Wash cut, place band aid on finger you mashed when hammer/chisel slipped @ 5 min per cut ( add three hours if stitches were required, add 24 hours if arterial bleeding took place)
Use correct size punch, your new set of gloves and a hammer to punch out the rivet body's @ 5 min each
Allow quivering fore arm to relax, punch out rivets on other side
Method Three
Grind off rivet heads @ 5 min per
Cuss and complain about the ford engineer who invented the frame rivet (Note, this is to be done continually during rivet removal)
Come to that one rivet that can not be reached with the grinder, go get cold chisel, pound for 10 minutes to get that head off
Wash cut, place band aid on finger you mashed when hammer/chisel slipped @ 5 min per cut ( add three hours if stitches were required, add 24 hours if arterial bleeding took place)
Use correct size punch, your new set of gloves and a hammer to punch out the rivet body's @ 5 min each
Allow quivering fore arm to relax, punch out rivets on other side
Argue with wife over why you are yelling at her when she says it's time to come in for dinner (PS, you were not yelling, you just can't hear a damn thing, so you were talking loudly, but you'll never convince her of that, I suggest flowers, a card delivered in a really cute way (in the fridge, or on her car seat, better yet sneak it in to her work place)NOTE: This last step is often common with most any task that requires using A: Air tools, B: A large hammer, C:Grinder

Re: Rivit Removal!

Norm or anyone else, would it be cheaper and easier with Harbor freights 4&amp;1/2" grinder (3 metal cut-off wheels incl.) and just grind the heads off???

I hate grinding things with these cuz even with safety glasses, a piece of abrasive or metal will most certainly find its way into your eyeball somehow doing this underneath the truck [img]images/graemlins/mad.gif[/img], but how hard would it be to just grind the heads off with a 4.25 grinder and punch em out?

I bought one of those grinders last week for $18.00 to finish my hitch project and it works great for the price [img]images/graemlins/grin.gif[/img]

Re: Rivit Removal!

One would assume so.
But, according to the above write-up....
Come to that one rivet that can not be reached with the grinder,
go get cold chisel, pound for 10 minutes to get that head off.


Are you replacing the axle pivot brackets, or the rad arm brackets?
I had bolts only, no rivets, in my axle pivot brackets. [img]images/graemlins/grin.gif[/img]

Re: Rivit Removal!

missed that [img]images/graemlins/crazy.gif[/img], which one is it anyways, maybe you can tackle it with a borrowed air chisel ahead of time (stick a temporary bolt in it if you need the beast to get to work everyday like me) and it will be out of the way for the weekend lift project [img]images/graemlins/smile.gif[/img]

boy , im off dreaming again [img]images/graemlins/smirk.gif[/img]

Re: Rivit Removal!

even when you grind the heads off some serious pounding is in order. at least with most of mine. [img]images/graemlins/mad.gif[/img] What I found worked for me best was to grind the head off, drill through the center of the rivit. then pound it out. It wasn't fun and my thumbnail is just now starting to look normal again. [img]images/graemlins/crazy.gif[/img] If I were to do it again I'd seriously consider some torch work but you have to be carefull melting them out like that. Take Care. NORM

Re: Rivit Removal!

if your good with the torch you can easily just cut the heads off without hurting the bracket.

Re: Rivit Removal!

I've tried a torch. It ruins the hole. Luckily I was cutting spring perches off a junk truck. I cut the backside of the rivet on the frame side and pried the hangers off (they wouldn't punch out). They also wouldn't punch out of the hangers once I got them off. I had to put them in a vice with a socket slightly bigger than the rivet head and use it like a crude u-joint press.

Since he has a 78, the only thing with rivets would be the rear spring hangers for the shackle flip.

Re: Rivit Removal!

That hard to get rivet on the radius arm brackets was a cake walk with the die grinder and a drum style sanding bit.

You'd think the 7" or 5" grinder would do better, but I swear the course drum paper on the 1" die grinder drum worked even faster.

First thing I did was read all the searched posts on this forum, Norm that has to be the most realistic portrayal yet !!!!!!!
