I purchased a new wood prop from Ed Sterba for my 180 hp RV-6A. I also

purchased the 2 inch machined aluminum spacer, crush plate and prop bolts

from Vans to complete the installation.  When I received the prop I

discovered that the bolt holes in the wood needed to be filed out quite a

bit in order for some of the bolts to be able to line up with the holes in

the spacer and go through the spacer into the tapped flange on the

crankshaft. With the prop off of the engine these bolts holes now seem quite

sloppy.  The enlarged portions of the bolt holes on the back of the prop

seem to fit very well over the drive pins with virtually no slop when the

prop is on the spacer.  I've been told that the torque from a 180 hp engine

into a wood prop really puts a lot of back and forth stresses on it. Should

I be concerned about the enlarged bolt holes (when the drive pins fit

tightly) or do I just need to make sure the prop is properly torqued and

check it often?  Thanks.

1)  Contact the prop maker



2)  Consult an experienced local A&P/IA



I am not suggesting irrational fear but you don't want to make mistakes

on prop installation.

Doubt many A&P/IA have much experience with wood props anymore,  I would 

contact Ed Sturba,

in the past I have found him to be a fantastic person to deal with.

As long as the the lug inserts fit tight you are going to be ok with 

proper torq but still get his opinion.
