I have two short questions after searching through the Archives:

1.  My bridle straps are clicking.  When I give the thing a twist to
tighten the strap to the wire, the clicking stops temporarily, then
resumes because the movement of the action loosens it again.  I have
thought to put a tiny dot of shellac on the wire to stabilize the
strap.  Any comments or advice?

2.  What is CA glue? (unrelated to above question).

Sincerely,
Larry Toto
