I just got an estate pipe with a lucite stem. I've restored a few pipes but never actually restored any lucite stems yet. The first problem with the stem is when you look straight down the stem it bends slightly to the left. It's something I could live with but would be nice to fix. The second problem is that there are light teeth marks on it as well. I'm not sure if you can fix this the same way you fix vulcanite with a little flame and rubbing it out. Any suggestions would be very helpful.
