    Bear with me as I work this all out... I counter-sunk the screws that hold the brass bracket so the doors lay flush. I had to grind off a little of the strut as well.

    Started locating and drilling the lower gear door mounting holes. I cut a plywood inner liner from the supplied kit doors. I'm thinking I should glass the door liner to seal everything up nice.

    Serious question, Have you ever considered Top Gun competition? This is definitely the caliber for Pro-Am scale at the least. I worked on 3 different projects for Top Gun this year and this plane looks to blow at least one of them away.

    Gear doors are final trimmed, drilled and the inner plywood liner installed using polyurethane glue. It's really amazing how the 1/32" plywood stiffens up the gear doors. I glassed the plywood just to seal the wood for finishing.

    Here's my idea to attach the gear doors.... I sheened this little 1/4" diameter coupler and threaded it with a 4-40 tap. I can now use a 4-40 screw to attach the door.

    Update... Here are the gear doors mounted for the first time. I turned all the little stand-offs down to .200 diameter to match the gear door clamps. I also left them all a bit too long for adjustment at final assembly.

    You might ask... Why all the trouble, just use a brass tube as a sleeve? Well... With a brass tube over the screws you would have crank down on the screws to tighten the strut door clamps thus crushing the gear doors. Capiche?

    Pretty proud of my new sheening efforts.

    Need to get some 4-40 countersunk screws and counter sink the gear doors so the screws sit flush. Maybe I can use a piece of fuel tubing between the standoff and the gear door for a shock mount? hmmm?

    Well... It took a little longer to sand and prep all the parts I wanted to prime this weekend. I sanded all the flow coated parts, cleaned out the hinge slots, sanded some more... bla bla

    After milling the slots in the lower gear doors for the sliding action, I decided to skim all the doors with microlite and sand em down.

    I machined these little bushings to fit into the gear door slots. Now I can tighten the door screws without clamping the two doors together. Works great!

    By the way... There's been a HUGE change of plans with the power plant that's been ordered.

    Here's a hint... It starts with an "H"
