43 forum posts 59 photos	Having recently bought and now checked over the 2A, I see that the arbor is completely plain; as in there is no milled slot to take any form of locking key to stop the cutters from turning on the arbor. Is the Centec unusual in this area or do I need to get a slot milled into it. The arbor looks original, left hand thread to undo, 2MT on the taper, just no slot in it? I couldn't check before as the machine was set up and had a cutter in place which rotated etc, so I took it for granted that it was all there.

My 2B, with a one horse motor, would not start in high gear until warmed up. I changed it to a 3 phase motor and no problem since. The 2A may well have a 3/4 HP motor (particularly if it is original).
