lunchmoney said:There is a product called Never-Seez that pipefitters use on studs to allow easy removal of nuts. Hardware stores or plumbing supply stores will carry it. The stuff is a graphite compound, slick and is very messy. I have used a very small amount on the pin and put the cue together and took it back apart several times and then wiped the pin off. It leaves a light film and will not dry, although it will collect dust. Make sure you use a joint protector. When the joint becomes tight again just re-apply. It will make a world of difference. A small can will last forever.
I want to clarify that Never-Seez is for threads on metal pins. I don't think you would get good results if the threads are made of wood.
