Just came across this thread...... Have I been doing something wrong ?
I've been flying for some 22 years now, and not once bothered to check for the ''tracking'' of a prop, although I do spend alot of time balancing each and every prop that comes in before it goes on the plane.
So how critical is this ????? I fly only sport-for fun only, no competition. I do want the most out of my planes and equipment though. Guess I'll go home and track all my propellers now. Great googly-gock !!! Something more to worry about !!
OK So now I want a tapered prop reamer. Cannot find one listed-Only step reamers. Where can I get one ?
Ditto on the tracking. Props have a slight tendancy to distort while turning anyway. And the aerodynamic characteristics change dramatically from the center to the tip.
I have never seriously considered a tapered prop reamer due to the very large probablity of error. And wearing open the hole. I have two stepped reamers, one standard and one metric. That way my hole is the correct size through the entire hub - and if I screw up I throw it away.
What if the hole is not straight ( square) thru the hub. You ream it with a stepped reamer and then all you have is the same size hole, but still going thru crooked. With a tapered hole, but still snug at the back, the crooked hole is no longer an issue. The slight taper allows the prop nut and washer to press the prop hub flat to the drive washer. If I had to throw out every prop I have had with a crooked hole I wouldn't have very many.
