Thanks for the detailed math explanation to the problem Marv. I can use that on my next wedge lift system.

I must admit that I used the DTI method to get a "close" solution. I just looked at my setup and found that
I have a .001" error in a full turn of the knob. One line is close to .001 but just a bit short. I usually work to .001"
for most of my builds and that is more than I usually need..However I always spend considerable time
fitting up the parts. So time could be saved with using the proper math for the solution.

Thanks again and Cheers, JR
