Best of luck with the "final assembly", and be sure to apply lubrication liberally as you do it.

Thanks Ken.

No added zeros, .0015" it is. I measured it multiple times and got the same result.

I'm going to do some testing of the power feed to make sure that works and then reinstall the DRO scale, if I can find it.

I decided to measure the travel per revolution of the hand crank just to see how it compared to the original lead screw and I consistently got .099". That's exactly the same as I was getting with the original lead screw. I'm assuming the diameter of the hand crank dial must be off a tad since I should be getting .100" of travel per revolution. How would I calculate what the diameter should be to make a new dial to eliminate that error?
