I have a new radice billiard. When I opened the box I noticed a hair's breadth space between the stem and shank. I actually thought about returning it but decided it wasn't worth the hassle. The pipe smoked fine. However, the tenon is so tight in the mortise that it is a real problem removing the stem for cleaning. It makes the most awful sound and is a struggle to turn it even a little. It really feels like the shank cannot take the pressure. and will eventually crack. I have placed the pipe in the freezer and this helps a bit but I still can't remove the stem and it still is difficult to move at all. Any thoughts and, if I am able to get it out, what to do? I don't think the old graphite trick is like;y to fix this. Perhaps sanding the tenon?
