Here is one of the motor mounts, just after machining:
And here is a part in progress:
The parts look beautiful, with practically polished edges, compared to the extremely coarse edges left by an abrasive water jet.
Wherever possible I used countersunk stainless fasteners, for added shininess:
One great thing about CNC milling parts, rather than water jetting them is that I can make precise press fits for bearings without any fiddling with tool offset. If I CAD my part with a hole .001" too small for the bearing, the mill machines a hole exactly that size.
And here's the assembled unit. It is still missing the attachment for the linkage on the output 60 tooth pulley.
