I have a Lee mould that has had the top shaved off to repurpose to another gun. I cannot keep the shoulder bolt tight that holds the sprue plate on. If I bottom it out it is way to tight and when it is just right opening and closing the plate causes it to back off. So, I need a drop of loctite. But, what number does one need to hold up to the heat of a mould?

Insight please!

Thanks Matt

Ok.. so I guess I will try to drill and tap in a set screw.

Yep, drilling 'n tapping a set screw is the way to go. I think Lee is dropping the ball by not having the setscrew in his molds from start. How much extra could it cost?

Or a thin spring washer.

Someone a while back suggested wrapping the screw threads with steel wool and running it back in. Cheap enough to try anyway.

I've mentioned this several times...but I will admit that I've never tried it. The risk is that you could wreck the threads in the aluminum block, so I wouldn't do it to a custom Lee mold or a rare Lee mold that I valued and couldn't easily replace it with a $16 new Lee mold.
that's my 2¢.

just drill and tap for a setscrew and be done with it! I use a 6/24 setscrew and it's the first thing I do to ALL Lee moulds that come into my posession, 2 or 6 cavity!
