Is there such a thing as this, and if so where would I get one? Thanks a lot for your help!!

And where would one acquire one, should one wish to do so?

I hear you can still get the 4-1/2 from Clausing without too much pain. I'm told the MT5 are available from many commercial sources, but have no examples.

Thanks BadDog, I might try Colchester over here then, as long as they don't want a small mortgage for parts.
I have a 4 1/2 MT in the headstock of by Bantam, and it would be nice to use 5C collets with it if possible.

I might have one to sell (5MT I think).
I'll check tomorrow.

Just find me one with a No12 Jarno taper & I'll do you a swap :D

Enco sold lathes with a 4 1/2 MT so they may have some.

I am looking for a 4MT not 4 1/2.

Thanks

afaik that was one of the reasons for the 4 1/2; that it was as small as you could go and still bit a 5c adapter inside.

No such thing, at least not with a normal MT4. You might be able to fund something for a 3C or 4C collet but you wont be able to fit the drawtube down the through hole on a MT4 spindle.

Best bet if you want collets is to use a collet chuck.

My Clausing 6300 has the Morse 4 1/2 spindle taper. IIRC, Rockwell also used it.
