The prop hub screws on fine but im driving myself silly here because I got a "wobble " at the end of my prop hub...+/- .004 and I cant figre out were is coming from. I tap my hole while the hub is still in the lathe so...[sm=spinnyeyes.gif]
thats why I want to know what angle the taper is on, so the next hub I make hopefully will have no wobble. The funny thing is, I never had a problem before this engine. Yes the crank is straight...I checked it with a dial indacator.
well see......
