This here looks a rather attractive machine particularly as it is on sale:

Trying to find out more about it I looked at the manual but it is quite
useless. One of the questions I had was how is the chuck attached to the
spindle. The dealer tells me that there is a "flange" but any further
details have not been forthcoming so far.

Are there any standards that would describe such flange attachment? Are
there standard sizes? I am concerned about accessories (5C collet chuck??).
This machine is BTW only superficially similar to the Grizzly G0602 which I
understand has a 1-3/4 - 8TPI spindle.


If it is the same as many of the 3-in-1 machines, it is a standard metric
100mm nosepiece that fits into a recess in the back of the chuck. 4 bolts
pass through the flange and are threaded into the chuck.
