Thanks Bryan!
The 3/8's drive speed wrench works really good, better than a ratchet for me. It hardly got used for anything else lately, so now has a new home. When I first assembled it, it was very stiff to move up & down. One reason being the largest hole I was able to drill in the plate for the socket to fit the filed nut on the rod was 3/4". And with the filed nut (1/2") not being perfectly centered the socket would rub significantly. Reamed that on out to about 13/16's and that made a vast improvement. I also coated the rod with a spray can of lithium grease, that was a significant improvement also. It now goes up & down much easier. I have the rail adjustment set pretty tight and had pre-coated all those surfaces with Johnson Paste Wax. It's a bit of an effort to move it, more than I imagined but moves with no binding or hanging up. I've never had access to a lift before so expectations are minimal. I'm sure I'll be tweeking it as I run projects thru it. I'll have more to report in a couple weeks.
