Shopsmith Forums

The recent discussions about the Nova G3 Adapter had me thinking.

The set screw on my Shopsmith drill chuck is NOT set at an angle.

Now I hasten to say that this has NEVER been a problem and I don't expect that it ever will be. It is just curious.

I checked some of my saw arbors (not all) and they seem to be. JUST CURIOUS. What is the criteria? Rhetorical question! I don't expect there is an answer other that "It just is as it is". BUT IT IS CURIOUS.

Indeed. And I wonder: is there any other non-slope-tapped adapter for which operational stresses are measured against the headstock? Tho, of course, at idle those forces are, well, idle.

[Hm, the more I think about this the more I wish I hadn't.]

Could be the greater mass of the larger turning chucks(and imbalance of work piece) creates the need for the ';sloping' set screw.

It is the inconsistency that I find curious not the idea of the set screw being at an angle to mate square with the tapered shaft.
