Paul,
Thanks for the comment but if I understand you correctly, we are talking
about two different things. It appears that you are talking about "a set
screw for locking the adapter to the chuck" body (something that the
Teknatool chucks use also--Oneway uses a different system with its
Taperlocks held with two screws), while the original questioner to which
I was replying was asking about the presences of a set screw for locking
the chuck/adapter assembly to the headstock spindle (actually on Oneway
and Teknatool lathes it is a groove in the spindle between the threads
and the shoulder). This allows for reverse turning and sanding without
the risk of the chuck accidentally unscrewing, as well as preventing the
same under sudden decelleration of the workpiece during forward rotation.

I have used an older VM120 which didn't have such a set screw, and it
appears that Jim earlier in the thread doesn't have such a set screw on
any of his three Vicmark chucks (/adapter assemblies). If I am
misunderstanding you, can you supply an approximate date of when a
spindle locking set screw was added?

Thanks again,
Lyn

To my knowledge, only Oneway and Teknatool provide chuck inserts with a
locking screw that will ride in a matching spindle groove. On both
chucks the location for the spindle locking screw is the same, so they
each fit the same grooves found on the Oneway lathes and the more recent
versions of the Teknatool lathes.

Just an aside about Jim's speculation. The Oneway taperlock spindle
adapters are unique to the Oneway products (chucks, vacuum chucks, and
some faceplates), and can not be retrofitted to other brands of chucks.

Though you didn't mention it, I'd suggest you not count out the new
Supernova 2 and Titan chucks from Teknatool. They are a third generation
design and a significant advancement from their earlier chucks (which,
if you don't know, were ground breaking for their day, as Teknatool was
the very first to develop a 4 jaw scroll chuck for woodworking).

I have heard many peeps say good things about both the Vicmark &
Axminster chucks, being of superb quality, I have not seen either of
these chucks & was curious to know if either of these chucks have a
locking spindle set-screw, as on the Oneway chucks.


Thanks

Bud
