I have a couple of screw holes open in the motor pan from my conversion of a Greenie headstock. Oddly, there was a Goldie motor pan on it, but a motor replacement had been done in that headstock by someone.DLB wrote: And a question: I went the DIY route, so my motor pan has a number of holes with no obvious utility, other than improved convection cooling. I'm wondering if those holes are present on the 'new headstock' version PPs. Specifically, I'm talking about the motor vent from the AC motor, the motor mounting holes, and the original power cord hole. If some, but not all, are present, please specify. Thanks.

In the belt cover there is the perforated nameplate, those holes probably get clogged quite easily.
The PowerPro motor incorporates a fan directing air mainly straight back from the motor. I think a vent is needed directly behind the motor so the hot air is getting out. Additional forced air through the access hole is a great idea, if you have an access hole, not cutting one was a mistake on my part. Maybe it's possible to remove the nameplate on the belt cover and mount a fan blade and housing on the aux spindle blowing air in to maintain overall positive pressure.
I don't see running this thing at high speed for long periods of time though. I think an outlet in the belt cover behind the motor will be a good start though. I could just drill a lot of holes for that, possibly adding a shroud to help direct the motor fan output.
