Tested on a Grizzly G0766 - 22" lathe.
The 2 spur drives came lightly oiled. Just enough to coat and protect against rust. The teeth and center point have been ground well and are very sharp. I tested them by mounting first the 5/8" in my chuck. No wobble, held the crap test spindle snugly when I tightened the tail stock. When I backed off on the tail stock the spindle was able to spin freely between the tail stock and the center point of the spur drive.
When testing the 1" spur drive I thought there was a problem. The center point wouldn't retract when I held it and pushed it down onto a piece of scrap wood. It made an impressive conical dent in the wood, but the center point wouldn't budge. I thought maybe there was debris or metal shavings inside the spur drive preventing the center point from moving. I unscrewed the set screw to look inside, and after spending an hour looking for the spring that ejected like a bullet (my fault) I looked inside and it was very pleasantly surprised. I didn't see any debris, metal particles or shavings. The set screw was tightened just a bit too tight and wouldn't allow this centers point to move. Problem solved. After that it worked as well as the 5/8" drive.
Despite the set screw that was too tight, I give this a 2 thumbs up for the quality and performance.
