Also, I'm curious about the gas lift. I can see that it makes going up easier, but doesn't it make going down, harder?
I checked this morning and the shortest movement at full speed was about 3/8". I need to change the speed pot as it is stuck at full speed but it might be possible for a smaller increment. I don't think you could hit .015 as the motor has some run on.
On my mill, with 2 springs the cranking force is about equal between up and down. When I only had 1 spring hooked up going up was hard and going down felt like it was freewheeling.
