Hi Philip, I liked the look of the K10 on the Axminster stand at Daventy last year, they said to have the K10 for the AWVSL Midi-lathe, (which I'd been looking at, as the wife had expressed an interest in turning herself, but their show price was dearer than from the shop) as the K10 takes all the 100m range of jaws, it's compact and light weight, but not in it's holding power, and cuts down on overhang.
They've since had a deal on K10 and I was going to get one to replacement the wife's super precision chuck which came with the M900 for that reason, I'd have her chuck and change the back plate to fit my Mystro, so I'd have 2 chucks...
.. the only thing that was wrong with that.. no not the wife.. there is a differance in the chuck key squares, with my 1996 model and the 2006...
... so I'd not have just the one key for both.. but mess with 2 and not have the right one at the time, so it didn't come about..
... or was I looking at it wrong and it wouldn't have been a problem..
Regards. David
