Current Prop is a Homebuilt  72 X 42, made from Five Laminates of Birch Wood, it has a Kevlar Leading Edge, wrapped with Fiberglass / Polyester Resin.   I've re-worked the prop two times, in order to get the performance tuned in.  At full power, level flight, the engine now redlines just under 2300 RPM.

November '02,  I grounded the airplane for a firewall forward retrofit, to a Continental A65 engine.

The cowling is a combination of fiberglass Nose Bowl, and flat wrap .030" 2024 aluminum.  The nose bowl was laid up in a splash (mould) made from a J3 Cub.  It was then bonded & riveted to the aluminum flat wrap.

Weight & Balance was estimated on paper, by removing the weight of the Model A engine at the given arm, and the addition of the weight of the A65 at an arm that proved to be 8" longer than the plans dimensions engine mount.  When the retrofit was complete, another Weight & Balance was done, and it proved to be EXACTLY where I estimated it to be !!

Orange cylinder base shows they are Chromed Bore.

New fittings were made for all four corners of the engine mount.

Now you can really see how far out that extra 8" on the engine mount looks.

I used the plans general layout of the engine mount, and the O.D. Size of the tubing, but because the mount is 8" longer than the plans dimensions, I increased the wall thickness of the tubing up one size.

The Stromberg  NA-S3A1 carb was disassembled, cleaned, inspected and reassembled.  I built the carb heat box, taking dimensions from a non serviceable unit.  I have since added mixture control cable.
