Thanks for sharing that Marc. I have used them too. Would like to see how you modified the door. I typically cut two half circles in the door with a strip up the middle for the screw stud.

Re: Control Cabinet Inlet Fan
I put 3/4" plastic spacers around the fan opening, with a bridge running diagonally across to hold the cover stud.
The screws that hold the spacers in place also secure the fan inside the door. I tap the corner holes in the fan: 10-32 on an english cabinet, or M5 on a metric cabinet.
The plastic spacers serve to locate and center the air filter.
This arrangement allows me to just drill an open 4-1/4" hole for the fan itself, with 1/4" thru holes in the corners for the screws.
Spacers are .75 x .75 x .26, McMaster number 92825A146.
Screws are 10-32 x 1-1/8", or M5 x 30mm.

Marc,
Is the "lid" just a shop-made flat plate?

Confidence is the feeling you have before you fully understand the situation.
I have CDO. It's like OCD, but the letters are where they should be.

Re: Control Cabinet Inlet Fan
Incidentally, it's a simple matter to control the fan with a domestic heating thermostat. Most of the time when the machine is idle the fan isn't needed but if the temperature inside your cabinet rises above 30C or so, that probably indicates heat is being generated and ventilation is advised. The rest of the time, the internal temp will be less than the max thermostat setting (hopefully!), so the fan will default to off when nothing is happening. Makes for a quieter workshop!

So what is that magic setting?
