Paul, take a look at this site.  What do you think? With this no drilling
or tapping.
  However we would have to use 1/4 20 push rod.  FWIW

3/8" Teflon is getting so heavy and expensive I am tempted to go back to
a clevis and 1/8th inch thick Teflon. Rev 7.  1/2 inch thick Teflon would
break the bank and the scale.

1/4 inch throttle cable is also over kill.

Paul,
Furniture suppliers have rod, drilled through the side ( rather than the
end) for locking together furniture and their very strong.
The rod is only about 1/2" and the bolt hols is about 1/4" ( from memory). I
have never seen one break - their also cheap as chips.
If 1/4" is too big make your own - drill and tap a bit of mild steel.

That is not the problem. The Teflon must be thicker by at least
1/4th of an inch than the throttle rod. If I went to a 1/4
inch throttle rod the Teflon would have to be 1/2 inch thick.
Teflon is expensive and heavy. The current 10-32 throttle rod is
3/16th and is the standard throttle cable available from Aircraft
Spruce. The cheap buttons we use now are called steel spacers in the
McMaster Carr catalog and are off the shelf.
