Clarkson Collets

Mark You have the old style of collet, with two uprights, which fits the old style holder. The newer ones, are with 2 flats as in the picture on the link provided. Bob

I forgot to add that the newer type are classed as the "S" type Bob

Thanks for the info, but do the older ones have a similar kind of name?

Thanks Mark

Mark, I believe the type you have are C type; they often turn up on the 'bay but aren't as popular as the S type so can be cheaper. Martin

Mark If you get trouble finding these, I might have a chuck and a couple of collets lying around.. You should note that the older type that you have use a tapered closing sleeve between the collet and the body of the chuck. The newer type "S" does not. Bob

I had heard of C and S-Type collets, but never really knew what that meant - I had thought it may be to with the size....

Mine does indeed have the tapered outer sleeve, so I guess it must indeed be c-Type.

Thanks very much for the information. If you do happen to have any collets lying around I would be more than interested.

Thanks for the suggestion of RDG, I have used them before, and they have been very helpful.

I tried G&M Tools today as they are just down the road, only to be told that the older, C type collets were never made in imperial sizes... Is this true? Am I going to have to modify a 5/8" one to accommodate a

Thanks Mark

Bollocks. If anything they would never have been made in metric. When the C type was relevant Clarkson and Herbert's ruled the known world. France was still smarting from Wellington giving stumpy a good hiding.

If you can hang on till after Xmas I think I may have some blanks turned up out off silver steel, unfinished on bore and drive pins from when i had one of these chucks. Can't check before as the big silver bird beckons, if the fog clears. Just hope that bloke with the scrambled egg on his jacket knows where the end of the runway is ...................................

Err, I just re-read what I wrote. I was told they were never made in Metric, ie were only made in imperial... think I got confused halfway through my sentence...

Anyway, John, unhardened blanks would be very much appreciated.

Does anyone know what the thread will be at the end of the collet?

Thanks Mark

OK, I'll have a look when I get back. Thread is always shank diameter x 20 even if it's metric so 6mm x 20 but 1/4 x 20 whit is fine. 16mm will manage with 5/8" x 20
