Hi folks.

I'm working on a couple of machinist jacks which are pretty specific to a single job, but I may be able to use them again. They're only simple aluminium rod, threaded with a stainless bolt with the head pressed into another bit of aluminium rod. As I said these are for one specific job, they don't have to last.

The issue is, with all small jacks I guess, vibrations move the bolt and you lose your support.

So, what can you ladies and gents suggest for making my threads sticky? I don't want a lock tight, I need to be able to adjust them, but don't want them flopping around.

On a couple of smaller tests I've tried some thick way oil, basic grease, copper grease, all with varying degrees of failure. I have some no-slip-belt spray somewhere, but I can't find it, that was going to be my next trial.

Suggestions?
Many thanks.
