Hey look! The legs go through the holes:
Isolate the bus bars from the base plate:
Those bars are squashed DOWN now! And they are still isolated from the base plate. Oh hurray. And the mosfets and diodes are still functional after soldering (PHEW)!
Here's the bottom of the plate. Man, I think I need to trim the isolation pad just a bit. haha:
It's almost done! And there is going to be VERY VERY good thermal transfer from those bars to that plate.
