I gather that when the "hammer" side wears down , it can be used on the "anvil" side. hammer=3/8" and anvil 1/4" thickness. I also have heard that some have taken automotive disc brakes and cut them down to the appropriate diameter/ thickness.

curious if the 75 hp is still available?

The holes for the pipes (n my cowling) are very close to the drawing dimensions. I have seen other aeronca's that have those holes cut up. Is this a common issue? ...

<<<,Copper asbestos gaskets>>> I got the no blo wspiral wounds. Had to trim a little to fit- interference with adjoining cylinder Curious about the coppers ... saw a blurry pic on Fresno's webpage/ Are these thin like the steel ones with the ridge that crushes on installation (and leak)?
