Title: Reaming a carbon prop
Post by: Mike Ferguson on November 30, 2006, 09:48:26 AM
How does one go about properly reaming a carbon fiber propeller?  I just went the other night to try putting an Eather carbon 3-blade on a RO-Jett engine ... of course, the prop doesn't fit onto the crank.

I don't recall ever reading how to properly do this ... is there some special way to ream out a carbon prop (and therefore avoid ruining a $30 prop), or is it "just do it the old fashioned way" - i.e., grab a prop reamer and start twisting?

HI Mike,

I just use one of the two Fox prop reamers.  Haven't had a need to try and find anything else to use.......... they have always done the job.

Thanks Bill - that's kind of what I thought, but I wanted to confirm that I hadn't been ruining carbon props (or at least putting unnecessary stresses in them) over the past few years ...   :)

I drill them out, myself. A mill/drill works wonders

This gentleman will custom grind any drill, any pilot size.  I've used them and they work great in a drill press.  Perfectly straight holes with no wobble or crookedness.  He also has a bunch of popular sizes already made up.
