Hi all....On a typical aircraft prop installtion, the heads of the prop
bolts are drilled and then safety wired. This works, because the prop

flange

has fixed threaded sleeves into which the prop bolts fasten.  On my Ross
PSRU, there are thru-bolts, and instead of the bolts being threaded into

a

fixed unit, they go through the crush plate on the engine side of the

prop

and have locknuts instead.  What might be the best method of securing

these

type of prop bolts?  Unfortunately, I have seen a few other rotary
installations with a Ross redrive, but never bothered to look to see if

the

prop bolts had safety wire, etc.  Thanks for any and all suggestions.

In theory if you have lock nuts you don't need safety wire.

The classic SAE 1 and 2 prop flanges for wood props have hat shaped
threaded bushings pressed in from the back side. These bushings are also
the drive lugs for the wood prop - you should not count on the bolts
to drive a wood prop - metal is a different story. Vance
