MEGAWATT Cooling Fan Questions
It's cooling fan modification time.
The louvered cutout on the aluminum case has 4 spot-welds in the hub. Any idea why?
I am planning on full-circle cut-out the holes on both Megawatts, then use coarse, very coarse, screen to deflect junk from falling in. Seems these fans throw a flow restriction hissy-fit at the first sign of obstruction.
Tomorrow is the start of final assembly. I picked up killer heat-sink blocks for the sides. And yes I will re-thermal-grease the bi-polar power transistors.
There's going to be a lot of "stuff" inside that old Sola case. So much so that I am going to have to use 16-gauge wire on the high voltage from the terminal block. But I have a Huey-grade aux cooling fan inside and that'll have to do... (or not).
