Great idea. I don't know how rigid it would be because I have never used liniar slides before.
I wonder if you could lower the knee all the way down and lock it off, Then make a new spindle that slides up and down the column dovetail with a counterweight just like the industrial machines do. You could then use the knee movements as a manual coarse adjustment for different size jobs. The screw would have to fit in close to the column. It wiould be nice and rigid. Just a thought.
