Merry Christmas All, I am finding the 8mm watchmakers lathe to be an interesting machine. As such, I must tinker. First, I'm making an extention tube to hold long workpieces, and have made a drawing of the drawbar. I would like to post this, since it might be useful to others, and since it might lead me to more pedigreed documentation. The drawing is from my measurements of one particular well used drawbar. Can I post a link to the drawing from this group?
I intend to ream the ID of the drawbar to 0.25" and insert a brass tube.
Again, Merry Christmas All. John B.
