‘Slotted’ MT2 arbor with mini-centre

[PaulRParticipant @paulr]

This came with my lathe: an MT2 arbor with lengthwise slots and, perched inside, a small centre with a hole as if for a tommy bar.

What's would this have been used for?

Basically its a step down set-up to use a No 1 morse centre in a No 2 taper bore. Hole through the small centre is probably an extraction device. Put a bar through and use wedges against the step down adapter or spacer to push it out by contacting aprt of the machine when the spindle carrying it is retracted. Flat ended centres like that are often too short to reach the extraction drift slots in spindles or adapters. Could be got commercially with teh hole at one time, I have one somewhere.

Thanks Clive, makes sense now! Not much use to me but will file it away for a rainy day 😀
