custom Quark case design

FYI: When you epoxy the internals in there, you may want to think about putting some epoxy on the caps. It won't be perfect, but should help pull some heat away from those caps...

oh oh oh, no no, there will be no epoxy to be had in this case, just thermal paste, arctic silver. It does clamp the board, so you don't need/want epoxy, and you can always take it apart too.

I have to get the distance right between the two plates, as to get a good pressure (but not too much) on the FET's for good coupling.

I am just modifying it right now, with heatsink bottom, and motor mount holes. It should be good.

Thanks Mach1stang! :027:

Alright, I now need to know the hole pattern of the RC-Monster heatsink.

What is the middle screw hole for on the heatsink? (motor mount ends)

What is the spacing of the fan mounting holes?

I'm kinda stumped on what fin design I should make on the bottom of this. I need to make it so they are durable, so you can strap the heatsink down onto something (FLM chassis for instance), or on the motor mount and use air flow effectively. I'm kinda leaning for serrated fins

Also, I really don't think fans will be needed at all on the thing, with a good fin structure on the bottom. It should keep the FET's very cool and happy, would be able to run all day long.

Does anyone with CNC experience know what the smallest feature (flute/bit) can be machined? Is it 2mm? And what about the end of the bit/flute, are the small ones round or flat, or both?

Thanks for the help.

Here is what I am thinking with an integrated heatsink, it looks pretty good too. Too bad I spent all day designing it when I have to completely redesign it when I get my Quark back (for measurements).
