Front Landing Gear Fittings
Back to work on the Jenny!
I got a call from Clint at the machine shop. The front landing gear bending jig was ready.
Other than pictures, I did not have any original drawings of the front gear fittings. Luckily, Doc Hood made some pretty accurate drawings. I used these drawings to design the bending block as well as the patterns for the fitting.
Here's another shot of the bending block. I had Clint put the 27 1/2 degree angle on each end. You'll see how this comes into play later.
Here's the process: I took the .063 in. water jet cut steel and marked the centerline. Here is where you make the first bend, mostly by hand, after heating the centerline. I used two vice grips, one on each end of the steel.
Heat slowly with the torch, pulling the ends downward. Sometimes, a few taps with a hammer made the steel follow the form. Keep the front end clamped. It helped keep things in place.
Then I flipped things over and worked on the back side.
The steel was a little long (about 1/16 in. on each side) so I cut off the excess with the bandsaw and a file.
The end was welded and the fitting pulled off the block. I started making the second fitting, but ran out of time.
While I was on vacation, Ed Rogers from Indian Lake High School sent me some pictures of their shop project. His students had made quite a bit of progress on their Jenny. I'm pretty proud of them and hope they keep plugging away.
Till next time, enjoy.
