Does anyone have any close-up photos of how they safety wired the prop bolts on a Hartzell CS prop? You have to run the safety wire though those roll-pins. What a pain. If you have to pull the torque up from the bottom, it seems impossible to actually set twist. Maybe if I twist both ends first... Hum... Anyway, some pics would be most appreciated!

Here are three pictures of the safety wiring I did on the Hartzell CS Prop bolts (photo of each pair of bolts). What do you guys think?

From: Richard McBride When my -8 was inspected the DAR told me the size of the prop bolts requires .040 safety wire. I had used .032. I didn't change the size and haven't had any issues. It was difficult enough using .032. I can't imagine the struggle with the thicker wire.

The manual for your prop should specify the required wire size. If it is a Hartzell, I'm betting it will call for 0.032" wire. The manufacturer's recommendation would trump anything your inspector might have lodged in his brain.

Here are three pictures of the safety wiring I did on the Hartzell CS Prop bolts (photo of each pair of bolts). What do you guys think? > They look fine. The only thing I would have done differently is to put a piece of small diameter nylon tubing over the twisted safety wire to keep it from wearing at the prop hub between the bolts. Note that this isn't strictly required (it isn't called for in the manufacturer's manuals, and many people don't do it), so I wouldn't redo things now. You can add this touch after the first flight when you pull the prop to switch to a shorter alternator belt to stop the alternator pulley from rubbing on the lower cowling.
