looks good, do you know the cut speed (mm per minute) as I would of thought just under a hour once everything is up and running is ok.

No. I'm not sure of the cut speed on the shopbot and the birch plywood. I think the longest time is the mill thru for the inserts and outline. Next is proably the ball lane.
The longest time is proably going to be tool swaps and re-zeroing the tool to the PFs.

are you going to spot screw holes etc in the understand as then some locator holes will be beneficial.

Lost me - your phrasing through me off.
Are you asking if I am drilling screw holes in the PF? If so; yes. The 1hr time includes drilling 7 different screw hole sizes. Some thru the board. Some @0.3" inches.
Basically; I'm drilling all the holes I should need for the top side; including ball guide rail holes.

As for the bottom; I'm not drilling anything except what is drilled from the top side.
