Hi Jem
The beauty of Myford collets is that they don't need a chuck. If your D-W
machine has been built 'to spec' it will have a Myford nose, in which case all
you need is a Myford closing ring (easy enough to pick up secondhand).
Myford have recently started making the collets again. They had them on their
stand at Ascot, but they're pretty pricey - around GBP22 each, I seem to
recall. The last time I bought some secondhand ones they cost me around GBP15
each. They don't appear very often on the secondhand market, and the dealers
know it.
Regards
Ron

Ron,
Â
I have no complaints about the quality of the Vertex chuck. My problems are
due to my inexperience/lack of knowledge about how to do things. My main
reservation about the Vertex chuck is that I reckon that it is too big for the
D-W. Another problem is the difficulty in fitting the cutters in the chuck,
(a) so that they are screwed in sufficiently to engage with the nipple, and (b)
without cutting my fingers to shreds! (I use gloves).
Â
Myford MT2 collets I have not tried in the D-W. I have a couple that I have
used on my ML10, but when I wanted a half-inch one, Myfords had exhausted their
stock and were looking around for a manufacturer. The trouble they were having
was that manufacturing prices in Blighty were so high that the retail price
would be more than people would be willing to pay.
Â
I eventually purchased a set of ER25 collets for the ML10, but getting these
to run true is a bit of a lottery. Apart from my inexperience, variables are
due to:
1. How accurate is the engagement between the ER25 chuck and the Myford
spindle.
2. The engagement between the ER25 collet and its chuck nose.
3. Ditto between collet and chuck taper.
4. Diametric difference between workpiece and collet bore.
5. Opportunities for fluff, grit etc to get into any part of the inter-faces.
Â
Time to put the kettle on.

Best wishes,
