Default MT5/5C collet adapter

Anyone know where these rascals hide? I have searched for three days and no luck. I would like to make a low budget closer for my 12X36. Most of my machining is small stuff. 5C collets and chuck would be just right.

WIZ I was looking at the following closer at Grizzly.

With part #1&4 plus a homemade hand wheel I would have a 5c collet closer for ocassional work..

I haven't gotten a response from Griz yet as to price and availability so I was looking for this elsewhere..

One place I worked at a number of years ago had several hardinge secondary operations lathe and machines. One in particular was getting that the runout on the collets were getting sloppy, checking the spindle taper where the collet tapers seated, showed wear and runout after a few million times of collets being opened and closed.

With some measuring and checking, one of our fellas did some research, and found a tapered bearing cup/race that was identical in taper and ID. The spindle was taken out of the machine, and it was sent to a grinding shop to have a counterbore to suit the cup ground in.

I'm thinking you could make some kind of holder for that same cup Moe, and a hollow shaft with threads cut to suit the collets could be made too.If you need dimensions, I can measure and take pics of my little Hardinge cataract lathe....just don't ask for them fast!

Bison makes a nice, 5C collet chuck. It would have to be way less expensive than most any other option.

If you go the collet chuck route, I bought a chinee chuck from CDCO and was very happy with it. I spent a hour taking it apart, cleaning, and lubricating it and it ran dead nut. For $139 it's an imprt gem.

Yes I have been looking at the 5C chucks. The cheapest with a D1-4 direct mount was about 250 plus shipping. Still wouldn't be as accurate as 5C collets. But when I find a collet adapter for my spindle I will get a 5c collet chuck. That way I use it for smaller work above the range of 5c collets.

I think what puzzles me most is the lack or absence of MT to 5C spindle adapters..I guess Grizzly is my only source if I can get the two replacement parts..

Thanks for the input..
