    DIY themowell from 1/4" tube

    Just now, I tried turning the end shut with a cheapie Harbor Freight bit and running the lathe backwards: It chipped the bit, but not really where it is important, and it did make the diameter larger and will have to turn that down. It seems that motion of the tool across the surface...
