Powering my rotary table

[metric_taper]

Nice job making the structural stand mount for the power feed.
I have used these as well, one I put on my lathe tail stock, the smooth slow operation controls the drill speed so I don't get chatter. This is on my small 10x24 bench lathe, and I can use very large drills (I've used a reduced shank 1.5" drill) as the feed depth is very well controlled.
I also put one on my drill press as a down feed, the only problem, it can't drive the pinion gear directly as it needs some gear reduction. I found a 10:1 gear box intended for stepper motors and put that in series with the power feed unit.
I have a future project to put this on my manual surface grinder, one would traverse the table back and forth, the other feed the table.
