Mark, you said; But something else WW said got me to wondering...."aircraft cranks have to be properly radiused when grinding, and most automotive machine shops don't do that".
I had a nice Jodel, high time engine. I sold it, and the buyer had some problems; had the crankshaft chromed up to size and reground. Was not radiused. Broke. Aircraft destroyed by landing in a mature fiels of corn. Also, I had a Crankshaft extension on Ron's 1 . After I took it off, I felt a LOT better. Sorry for your problems, but it sounds like you handled it REALLY WELL. Good for you! Ron Freiberger mail to ronandmar...@earthlink.net <mailto:rfreiber...@swfla.rr.com>
