for $137 each do not sound too good. Any leads on used or new would be appreciated.



Thanks for your time,

This is why it is not a good idea to buy machines with oddball/proprietary spindle tapers. This has got to be the least common taper Bridgeport ever used.

If you make some spare collets or end mill holders, please let me know. The B3 size looks like it will fit my "Eklind" mill head.

The Eklind (about the same size) fits nicely on the Hardinge.

Well, if you have a taper attachment, that would be fairly easy to do, especially once you've set it up, to make a bunch.

Well, we made one, put it in the head (which isn't attached to anything yet) with an end mill and tightened the draw bar and it seemed to be true.

We don't have a taper attachment, we had to use the compound.
