+There are feedthroughs that probably allow unbolting a lower stage without unbolting the upper stage (ie remove XY stage from a baseplate)
 Looks to be 63 mm bolt spacing
+Looks like you need at least 0.15" clearance from bolt shoulder to top. I observed that 0.155 bolts were getting scraped, 0.150 seemed fine. To be safe, I turned bolt tops down to < 0.13. This was done by holding bolts in a drill while using a Dremel cutting wheel to sand them down.

 If you crash the axis, an internal shaft coupler may shear (oops). TODO: figure out replacement part number
