What its only my hobby shop lathe. The 3 is the spindle bore, nice for making smallish drive shafts. I've filled it in both directions, a brake drum from a D5 Cat just fits over the ways and have repaired augers that were the full length. Was afraid to remove the gap so had to turn shieves on the mill. But it will do the small stuff too.
