    Thx for the heads-up, I wasn't sure. I do know the 10L was 1-3/8

      I do know there is something special about this machine. The X in the serial number is something 'special', but I cannot identify just what it is.
      I guess I just drive up there and take a look.

        I'm wondering if that weird cross-slide is actually a taper attachment, it would make sense for a guy doing pool cues

          It's not a taper attachment. The cross-slide arrangement doesn't show up in any catalog that I can see. It might be an end user modification. I wonder if the "X" is for the gap bed.

            I'd suspect some pretty bad wear from 30 years of dry usage.

              Maybe not. After all, how much useage does a poolroom give a lathe, an hour a week max is my guess.

                Eh, a lot of misinformation in this thread (eg- there was no large bore option for the 9" workshop), but SLK001 is leading you in the right direction. It is a 10K (light 10), all of which have the 1.5x8 spindle nose, but slightly larger bore than the 9". They all take 6K collets directly in the spindle. The special sauce on this one is the gap bed, which is probably the 'X' in the serial. That option includes other oddities like integral bed feet, and the 'extra' dovetail on the cross slide to get the tool closer to the chuck when the gap is in use.

                  Interesting comment and sounds totally reasonable

                    FWIW there is a "9L" restored in the SBL group on PM:

                    And his restoration thread :https://www.practicalmachinist.com/v...ration-252299/

                    So I guess it *was* possible.

                      That is not a 9" Workshop. That is a 9L. Completely different lathe, more in common with the 10R and 10L (Heavy 10s)
