With the excellent result achieved with the improvised spin coater, it becamse sacrilegous to leave it at that, dangling wires and crappy mounting.
Thus, I set myself on the task of building a nice enclosure. First I quickly modelled everything in Fusion:
A thick base was added, so it's weight could act as vibration dampening. It would have a recess for the vacuum pump, as it was 8mm thicker than the power supply, and also a hole for the vacuum adapter for the motor to fit in. Resuming, I wanted the thinnest possible unit.
With that, I set up workshop to machine, cut and weld everything.
First, pump recess machining:
Halfway there:
The acuum adapter connector was changed to a slimmer one, and thus, the shape of it's recess was also changed on the fly:
Top side:
Pump clearance with the power supply:
I also added suction cups.
With that done, a stainless case began to take shape:
Spot welded:
Fully welded and blended:
At this point, since I didn't had neither AC connectors nor panel mount buttons, I decided to leave the case like that, and just attach the controller to the outside with double sided tape (over kapton for easy removal) and wait the components.
working placement:
