Dumb Cotter Pin Question

[Sputter]

The prop shaft cone/nut on my ’56 FD-10 needs a new cotter pin.  5/32″ is too fat, 1/8″ feels loose.  I put a 9/64″ drill bit in the prop shaft hole and it fits perfectly.

I can’t seem to find a 9/64″ pin anywhere.  So the question is, does it matter?  Should I just use a 1/8″ cotter pin and pull the head in as tight as possible?

I also don’t know if the nose cone/nut needs to be torqued, or just snugged up and pinned.

Thanks!

Wow!  My paragraph vanished! LOL

The cotter pin in question is for the propeller cone/nut on my FD-10.  A 5/32″ pin is too big, and a 1/8″ feels loose.  The hole in the prop shaft perfectly fits a 9/64″ drill bit.

I can’t find a 9/64″ cotter pin anywhere online or at local hardware stores.

Should I just tighten the cone until it’s snug and make sure the 1/8″ cotter pin’s head recedes into the cone?

the cotter pin….  even if smaller will do fine   it just stops the rotation of the end cap  so there is no  big strain        you have no choice other a  piece of galvanized  hay wire to lock it in place  or thread the hole and use   a bolt and lock washer
