Re: Tree Journeyman 300

Dan, thanks so much for your time, I will contact you about the
manuals. It is actually the front of the knee where the saddle rides
where the rust is. What model KB did you use. I plan on gutting all
the drives, I don't see the benefit of messing with that old stuff.
What kind of accuracy are you getting with your unit? What about
tramming seeing how it is a rigid head machine? How far did did you
tear your machine down? I am just finishing a rebuild of a BP series
one. Thank you again.

Ian
