Build an Excavator from Scratch

[frizzen]

Nice machining! That slew motor clamp with dovetailed adjustment is really slick!

I'm not sure if adjusting your feed speeds for the material might help with edges on breakout, or if i'm just used to seeing parts after a deburr tool has done a little chamfer.

The micro bench sander could be its own write up over in the Tools section.
