I found some time and worked on the rudder pedals a bit this weekend. First, a suggestion from a friend was to get some 6063 bar stock from a local place for easier bending for the rudder pedals. This worked and was a lot less cutting than the 2" wide piece of bar stock I have been making all my parts from. About an hour after cutting the two pieces to length, I had them both bent (using a spare drill bit to make the bend radius) and then spent some time getting the pieces mounted to the pedals and symmetric left and right. Then I made the little support pieces from 1/4" x 0.035" tube to triangulate the structure.
Here is an overview picture of the control rigging. The piece of white going from the pedals to the nose bolt is just string and will get replaced by some 3/16" shock cord, per plans. For now, it's just providing some resistance so the pedals don't fall over!
The elevator rigging is about how it'll be. I still need to get some larger washers to hold in the turn-around pulleys mounted in the center of the photo. I only had some small AN washers on hand.
Anyhow, yeah the control rigging is coming along nicely. Here is a closeup of the line guides on the control rod tube and the front seat tube. In earlier photos, I had the elevator line guides on the bottom of the tube, before I realized they went on top. I just flipped around that tube :-)
I also put in a little plastic end cap in the aileron torque tube, you can see on the right middle of the picture. I liked how the plastic caps dressed up the front and other tubes, so I sampled one that would fit in this location. Much prettier!
One more thing. My homebuilder buddy has made custom seats for other folks using foam bases. I'm hoping we can get together to fit the space better and be a bit more secure than the parachute cord version.
One other thing. I put in an order for 25 quick-links, several 2" marine snap hooks, and a few stainless steel rings. They should get here middle of next week. Cool, hardware!
