Mark I think the nylon screws are still a good idea. I don't think you would
have had a problem if you had diped the nylon threads in wax first then they
probely would have come out a lot eaiser.

Excellent comments on the self lock crimp on the nut plate. I just finished
removing the nylon screws starting with the very smallest bit I had and
working my way up to the crimp size. I then used a tap to start the threads
till I felt the tap grab the nut plate then I backed off. I then carefully
inserted a screw in each nut plate and threaded it in till it started to
grab. Everything seems ok now, thank God !!! Learn from others mistakes and
save you a lot of grief. I hope someone else will benefit from my mistakes.
You can bet I will not try the nylon bolt thing again. Now on to making the
counterbalance arm.

nylon screws wouldn't get hung up, but I long ago concluded that experience
doesn't mean anything over ideas on the net. You should be able to run
through a drill a bit smaller than the crimp on the self locking threads in
the nut plate. The only thing left should be some nylon residue that you
can be rid of by simply running a screw through the nut plate.

the nut plates when I floxed them in place. They threaded out reasonably
easily leaving the nut plates ready to use.

the self locking capability of the nut plates. If you can't get a screw
started after drilling the nylon screws, start a tap into the nut plate, but
just run it in deep enough that you can back it out and run a regular screw
through the threads.

had put nylon screws in the nutplates to prevent this and theirs easily
removed after the flox dried. Well....mine did not come out and now my screw
holes are plugged with nylon bolts. Guess I will have to carefully drill
them out and tap the nut plates to get the threads clean.........anyone know
of a better way to get them out??????????????? Man, it is always something.
I gotta get bird in the air before I go crazy.
