Z-axis rail posts added

Ok.. I got the z-axis rail modded.  I’m don’t like the way the mounting  on the Sherline looks.  It just seems like it would be subject to a lot of deflection.   I added some additional mounting holes for the revised base.
I copied the z-axis rail to a separate file and did my mods.   I hosed a few things up a few times till I got the way I want it.   Anyway.. Here it is.  I think the next step is modelling the ball screw thread.
