Rivet Squeezing RV-4 Wing Spars

280FX

Member
I am building a F-1 Rocket and just finished riveting my R-4 wing spars using a pneumatic squeezer. Those 3/16” diameter rivets requires a tandem-piston (6000psi) to do the job. I got my pneumatic squeezer from Joe Krzyzewski of Atlanta Air Tool, Taft, Tenn. Joe custom manufacturers various squeezers/yokes and is very knowledgeable, professional, helpful, and friendly.

Joe is good friend with Bob Avery of Avery Tools, who has a custom yoke specifically designed for squeezing the 3/16” rivets on RV-4 main spar. Bob was kind enough to loan me his yoke. I also made a jig out of scrap 4X4” wood to hold the squeezer, which is easy to move around my work bench and clamp in place. This made the task very easy and fun to do, I am very happy with the results.

So, I want to give much thanks and kudos to Joe and Bob for being so helpful.
