Hi, I'm David Mack. In 2006, I decided to build my own Van's Aircraft RV-7 200+ mph two seat homebuilt aluminum airplane and this is a log of the experience.

Gear Pant Centerlines, Misc
(Firewall Forward, Landing Gear)

Today I worked on the wheel pant center lines again. I got this idea from another RV-7 builder on YouTube (link). I clamped the trailing edge of the pant between two straightedges to get the pant vertically aligned.

Then I measured up from my flat workbench with another square a set distance from the table on both sides. I used that to mark a center line at the joint between the two halves.

And then I used a laser line to connect the center at the front, joint line, and aft.

I read some reports on VAF about people getting wear over time between the engine mount and zip ties from grit. I used a suggestion there and placed a layer of silicon fusion tape between the ties and the mount. I also applied a layer of UHMW tape over the electrical tape on the gear legs. I was pretty sure the fiberglass from the fairings was going to wear the tape down over time.

I also decided today that I'm no longer interested in tracking time worked on the project. I think it's counterproductive and hurts motivation. I'll leave the times on all of the previous entries, but I'm not planning to include hours worked on any entries from here on out.
