The motors on the X2 mills reportedly run hot during continuous use. I decided to put a fan on. I found a 12V fan of appropriate size in my junkbox.

Marking out the fan and motor bolt circles on some 1/4" aluminum stock. Partway through bandsawing it out now.

Finished bracket. The ID matches the opening of the fan, the OD matches the motor. #6 screws go through fan into tapped holes; motor screws go through.

Long screw below fan is one of the original motor screws. I need some longer ones now.

For some demented reason I always keep the little "wall wart" transformers from old electronics. This one was for a cordless phone that died years ago.

I wired it directly since I'll switch it through the master power strip for the mill.

The screws holding the end bell on the motor are 4mm. I need some 50mm long to go through the spacer, some 5/8" standoffs, and the adapter plate. No such things were to be had locally, even by special order. I'll order some 4mm threaded rod from McMaster later.
