Total Z-Axis Travel and Table Clearance?

[KevinP]

Hey, I'm looking for a couple basic specs. I haven't got plans to pull them myself, and couldn't find them on searches.

1) What's the usable z-axis travel for the Mechmate? I gather it's different for the 4 and 6 wheel Z-slides.

2) What's the gantry bridge clearance height over the table?

Under gantry (pending your spoil board thickness is between 9 and 10.9 inches)
Z travel with options 1 and 2 are 7.9" or 11.4" respectively. These are close estimates pending your choices on the build.
