I bought a new Lee mold. Casting started well and then the sprue plate got loose and gave me all types of headaches.
Anybody know how to secure the sprue plate? Loctite?

Without seeming like a smarta**, keep a screwdriver handy, and if you take the screw all the way out put a small bit of steel wool into the hole and retighten your screw.

Don't the new ones have LH threads now?

I have drilled and tapped a set screw in several of my Lee molds, the last one I did was the new style so I don't think the thread pitch or direction much matters. It's easier to just do it and be done, rather than "screw" with it continuously.

LH threads .....Yes and my newest mold's sprue plate was very easy to open with the screw tight so the venting may take place under the sprue plate. I have been trying to tighten the screw too tight to keep it from coming loose in the past. Thank you to Tom W for the steel wool trick.

LH threads ? But, I don't have a LH screwdriver - ****, nother trip to Harbor Freight !!

Actually, I just drill and tap for a set screw in any mould without one already.

Drill & tap for a set screw.

Yes, drill and tap BUT!!!!!, either get a brass set screw or put a piece of lead shot between the set screw and the screw plate screw so you do mess up the screw threads, which will mess up the threads in the mold when you remove the screw plate screw.

I hope I don't need to remove the sprew plate screws on my Lee molds! I know, I might need to, but alas, I used cheap HF drill bits and taping bits to do this. I pretty much just used cheap screws that I already had and surely jacked up the sprew plate screw. It does work though. I got tired of continually using a screw driver during casting to keep it tight enough. Just put the sprew plate screw right where you want it and tap from the side, and it should not go anywhere. It's working for me for now, but I may need new sprew plate screws in the future! (Anyone notice that automatic spell check keeps wanting to change sprew to spree or screw?)

after a casting session or two I go back and tighten the set screw/lead shot again. Stays tight from there on out

How hot are you letting your mold get?

Does the steel wool protect the threads of the sprue plate screw?
