I'm using a K10, which I must say I am pleasantly surprised with.
I have also pre ordered the Evolution from Axminster, but they have failed on delivery dates twice now, which is disappointing. I talked to them last week and they informed me they were having problems with the manufacturing process. I am in no rush, but if I didn't pick up the K10 I would be in quite a pickle, new lathe no chuck.
Also I have a just received a 11/4X8tpi back plate for my old multistar chuck, it allows me to use the wide array of attachments to the chuck system I have from my last lathe, I bought them in the late eighties and it has stood the test of time.
Woody kindly allowed me a try on his Maxi with the versa chuck, and I thought it to be a good solid unit.
Kind regards
Aden
