Adhesive

After years of looking, I recently obtained a pair of the old Piper
Cherokee logos from the center of the old style bow tie yokes. They
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.

Velcro? Maybe a little tacky.

What about rubber cement or double sided tape?

Shoe Goo (Goop?) usually works great in a lot of these situations. If you
use the silicone be sure to use the low odor kind to avoid having corrosive
ammonia fumes drifting around the cockpit while the silicone is curing.

It is not ammonia, it should be a vinegar smell and is acidic acid I
believe. But that is a good point. Use the humidity curing RTVs.

It's highly unlikely the Silastic RTV (TM) would hurt many plastics.
OTOH It might not stick well either. Nearly all RTVs use the moisture
in the air to aid in curing.

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.
