If both ends still work, you can take two 1/4-20 nuts and screw them on,
then tighten them hard against each other at the outer end of the bolt.
Hold the bolt from turning with them, then tighten the nut against the
insulator with an open-end wrench. Then be careful not to tighten anything
on it too much. This has worked well for me.

Subject: [TCML] loose NST posts
I have a 15/60 Franceformer that has many long runs 5-8 minutes
on old coil. Have obtained a new one and am going to parallel it to power
upgraded coil. Noticed the HV posts are loose and would like input on
tightening things up before running. Have looked at various methods,
heating to melt tar to completely re-potting. Am worried about integrity of
loose posts. Any suggestion would sure help. Thanks and will definitely
post pics of upgrade when done, this time ! Thanks to everybody at TCML.
