Chapter 9 – All Main Gear

Now that the bondo–between the wood main gear jigs and the main gear–is completely cured, I final sanded it along with the glass on the gear in between the tabs.

I removed the gear bolts and removed the gear bow from the fuselage.

Chapter 9 - Main Landing GearI then went on a foraging mission for materials at Praktiker & Toom (German DIY stores).

Upon returning from a successful buying venture, I marked the center of the steel gear tubes on top of the main gear & glued on two (2) small marker tabs (and marked the CL on the gear bow with a Sharpie… just in case).

I prepped the workbench in the downstairs shop with spare wing foam pieces that I secured to the table, and then got the epoxy and glass ready (the glass that Gina had spent about 2-1/2 hours cutting…Hoo-ah! It’s awesome having help!).  I took the main gear bow down to the prepped workbench and secured it to the wing foam & table.

I also went back to the gear–with the layups being a little gummy but starting to harden–and knife trimmed the gross excess of glass (it looked crazy but it’s structurally correct… promise!)
