bucking rivets

[bob johnson]

so since I am fast approaching the riveting phase..(literal, not figureative!!) of my project... I looked up some rivets, and some tips. last time I did some rivets I just supported the outside from under the boat with a fixed shaft on the head and the boats weight on the rivet...and I punched the inside with a hammer and punch to flatten..

seems there are pneumatic tools that do it gradually....but it looks like some people use the air tool on the head of the rivet and the buck on the small end... and some people do it the OTHER way....they buck the head and wail away on the small end to flare and flatten


which is the best???
I am wondering if using the air tool on the rivet head and bucking the small end puts stress on the aluminum sheet metal.....because essentially you are pushing the rivet into the metal even though it is already "home"...so to get any movement...you are flexing the hull and rib.....

what do you think of this method??? seems like it would put pressure on the hull as well as the rivet head!!


PS , no really need to watch , after the guy bucks the rivet completely.... the rest is just him getting ready for other work!!!

The rivet tool is supposed to be applied to the head of the rivet. The bucking bar is not wedged in place, nor is it overly heavy. It's supposed to "dance" on the end of the rivet. It's the resonant impact between the tool and the bar that ultimately squashes the end. I used the following links to pattern my methods when I replaced about 3 dozen rivets successfully. The video is particularly helpful. - Grandad

+1 on the air riveter going on the head of the rivet. The rivet set should be matched to the style / size of the rivet as well to provide even contact.

I recommend doing several practice rivets on something until you get the feel for it. I did and I think it helped my solid riveting job. Probably should have practiced more actually.

Definitely, practice is GOOD... take your time and be careful if you use a rivet gun or air chisel, its easy to bounce off the head of the rivet and you can end up with a bit of character.
