El Beast - Initial design phase, comments and critique welcomed!

[Zeeflyboy]

So managed to find a bit of 20mm plate that was big enough to make another part from, not for the lower frame which I had intended to build first - this is the Z-axis mounting plate but given that I don't have the plate to make any other parts at the moment I thought I may as well crack on!

Few little design tweaks before I made it, I've added a fillet to the risers in order to help fold the brush strip out of the way in a controlled fashion, and I've made one bolt on each of the carriages into a DIN7 shoulder bolt so that the thing should have no choice but to be aligned square with the rails.

forgot to take a setup pic, so here it is getting started after the first drilling ops:



Top side done:






Drilled and inserted some dowel pins to align for rear machining, it just needs a pocket to clear the motor mounts cleanly and while I was there a threw a little chamfer around the contour:






Finished part:
