Ryan,
I'd watch to see how thick the copy comes out this time, especially after
finishing. Also, if the old prop uses a Clark-Y (good chance) then you
may also was to carve out the shallow cusp on the bottom. Clark-Y is
not a flat bottom.
If you know that already then nevermind, of course!

Thought about carving your own? It's not all that hard if you have a fairly
undamaged 1/2 blade to work from. A router set up in a simple 3D pantograph
mechanism can be cobbled together for a one time use with all kinds of
'spare' parts. Just takes a bit of imagination.

Way high priced IMHO (and the only thing with a patent is the bicycle hand
brake addition) but it showes just how simple they can be..........
Laminate the blank one weekend, build the prop carver during the week, patch
the old blade and cut the new one the next weekend, ballance, drill, and
finish during the second week.............

I tried copying a prop borrowed from a friend.
It looked nice but when I tried flying it, I had no climb or speed,
the original was at least 50% better.
I am going to give it a try again and this time I will be more
careful with the finish sanding, must have changed the profile enough
to make it useless for safe flight.

Hi Brian,
It was a Great American prop from a KR-2. My first try was with
mahogany and failed a full power static run-up, cracked a blade.
the 2nd one was oak wood and looked good to the eye, static test good
RPMs just would not climb. put the original back on to be sure it was
not the engine and all was normal.
Will make the next one out of Birch the preferred wood for prop
manufacturers it seems.
