+====== Bolt pattern ======
+M4 screws
+For some reason the counter-bored holes at the base are tapped. I drilled them out to make an M4 bolt slide through
+  * #14 (0.182") drill to match existing holes
+  * Note M4 diameter: 4 mm => 0.157"
+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

+====== Assembly ======
+To remove the shaft coupler: remove the set screw at the bottom of the stage. Then rotate shaft until the second set screw lines up with the just opened hole
