Joggle technique
by Bryan Cotton » Sat Apr 18, 2015 3:18 pm
I first figured out this technique when I was installing a leading edge landing light in a C140. Shown below are the instrument panel cross tie plates. The bottom of my panel was .070" high, so I either needed to shim or joggle. I took a couple of .090" scrap pieces and put a radius on one edge. Then I taped them to the piece I wanted to joggle:
Then you put the part in the vise and honk down on it. Make sure you polish the edges first!
Came out good, no extra shim weight required, and I have .070" of extra legroom.
The .090" shims worked good for this case due to springback. Always good to work it out in scrap first.
