Mother said "Never bite off more than you can chew.", and this roughing mill can chew a lot. Here it is shaping the caster mounts (4 at a time).

Outrigger Caster/Mount
These soft casters are to stabilize the "pitching oscillations" that the old drag springs couldn't elliminate. The caster mount doubles as the "anti-perch" high point in case Tesla gets knocked onto its side.
