Zeropointbug: do you have dims for your clamp parts?

Generally: Would there be any sense to separate the power section from the brain section? To my knowledge it needs only some extensions to wires. It may be easier to put compact heatsinks to both fet sides and take the brain section which does not heat to more "safe" place to avoid short circuit and hit. Longer wires in this case are not length sensitive, I suppose? Just a thought...

You welcome,

Well, I was not sure which one would be easier to make. At the end two identical plates and two side panels complete the conversion. But you need to mill inside copper plate to clear electronics components on pcb. You can see that here. Also adding insulation tape was just to remind that you need to make sure that copper doesn't touch any electronics components.

You do not really need finned heatsink for middle fet's, what you need is means to squeeze two pcbs's tight and get transient heat from fet's to pcb as quick as possible. Quark's pcb is very thin and cannot accomplish that task, so you need to add metal bracket. Aluminum is not as good as copper, but you can try to do the same thing with stock heatsink plates, just replace foam with grease and you should be half the way to success.

Overall, you asked for dimensions, I think I provided a little bit more. You can customize this drawing to your like and so...
