Yep you're ahead of me derf, I'm also eying that it looks like where the belt guard attaches, there are threaded througholes that lead directly to the bearing race, If they aren't airtight I could thread npt fittings into them and direct air right against where the heat is generating, I was also considering maybe something like a PC water cooling rig to run coolant through the same path through a radiator and back.
Its all up in the air, let me get this thing dialed in a bit better then i'll worry about higher rpm, I was just looking to cut machining time down to save time.. and reduce the heat buildup since it only starts getting really bad about 15-20m into a run.
