Wanted to do this for awhile now. Have some parts but not a full plan. Going to start with the battery adapter. I have a piece of 0316 stainless that I will turn down, cut some 12mm x .50mm threads, put a spring pad contact point in it and find a way to mount it. The pipe is an old one that I have had for years. Never been smoked, just sat in a box in the back of the closet. I have a 601 pipe now, it works OK for short runs. 99% of my pipes are straight pipes because I like a straight pipe. Going to need some help on the battery setup. I think for the first run I may just make a contact switch on top. Who knows where this will end up. I'll post pics of all the lathe and mill work as I go. I have found over the years the best way to finish a project is to just start, so that is what I'm going to do. If I break something or screw up I'll share that too. It's all part of having fun. Enjoy.
