The post Sedona Update- after Sun N Fun and a discussion with Jimmy Brod of JB Aircraft Engines, it was clear that my intended engine would not be what I expected. The engine came off a turbo normalized Twin Commanche. Good engine fit for the Thorp....But, I'm not using the turbo part AND the pistons are rated at 6.5 to 1. That would only give me about 145 hp. Not good. So the engine took a nice ride on Yellow Freight. Jimmy's shop will install 9:1 pistons, new rings and then put my exhaust system on the engine and run it in their test stand. When I get it back - before the end of May- All I'll have to do is add engine mount, fuel lines, P leads and she's ready to run on the airplane.
In the mean time, the panel is almost all connected to the airframe. I'm making my final assembly list to make sure I don't have to install/uninstall items too many times.
The last 'big' install is now the windshield and canopy.

The windshield install has begun. I've made two passes with the Dremel cutting tool. It's about time to go with the belt sander for final fit.

I had to install the ailerons, counter balance weights and wingtips to check the fit and gaps.

Left aileron and trim tab. The figelli motor is inside the aileron using a 4-40 rod from the Hobby store to drive the trim tab.

I have the initial size of the windshield done. Now I'll drill the holes and finish the edges. Thanks to a quick call to Cubes, I'll work down to 400 grit sandpaper to finish all the edges.

You do good work Terry. Just make sure all of the edges look polished. Holes too. No chips or imperfections on the edge.

A Unibit works to remove burrs and polish the attach holes . You can use it on both sides of the hole . Practice on some scrap first . ;)
