After years of looking, I recently obtained a pair of the old Piper

are in fine condition and really jazz up the cockpit

I am unsure of what to use to mount them in the semicircular recess in
the yoke. I would not want to use an adhesive that will react in some
way with the "plastic" yoke and weaken them. There is already a
recurrent AD to check these yokes for cracks, so these pot metal
emblems will need to be removed from time to time for inspection.

Bruce,
A couple of years ago, I attached the yoke badges on '76 172M for a
flying club on our field.
The club mx officer had tried a hardware store variety of silicone that
didn't hold. I used a doublestick tape called VHB made by 3M. Very
amazing stuff... it's still holding and that's in a club of 50 pilots
and 4 planes! I got the tape from my 3M rep but I think they've
started retail distribution.
It comes in different thickness of foam substrates - a slightly thicker
one might be good to split the foam when you remove the badges for your
yoke flex test... or maybe you could use 3 small dots of tape.
Whatever you use, be anal about cleaning/prepping the surfaces, it
really makes a difference.
