I have two old ones ready to go. I am a Machinist by trade closing in on forty years in the trade. I really need to get a hobby lathe for home, only so much one can do with a drill press(I have done "miracles" with one though) and imagination. I will God willing have a Milling machine and a lathe before I retire. These days I would not dare bring any part from a PB or an AG into the plant, Things ain't like they use to be. I am going to make some Delrin seals and try to make them close enough that I only have to lap them in after pressing in.
I'm not a machinist but I do have a 1930s South Bend lathe.
