IGBT looks good
Yeah, that IGBT looks like "the ticket". However, I've got to use the MOSFETs right now because of budget constraints.
I think I'll try a combination of the suggestions you guys have made. See how this sounds. I'll use flat stock for the buses, heat them up a little with a torch then use high wattage soldering iron to finish them ASAP, line them up with heat sinks and add a fan for good measure.
I hope this works. If not we'll have to bite the bullet and go the IGBT route.
Thanks,
