My plan was to hit it with a bit of sand paper just before connecting.
Again, I'm not an expert, but I think I remember reading that sandpaper
isn't so good for this. It roughens the surfaces, and that actually reduces
the heat transfer.
Someone correct me if this is wrong, but I think a very fine abrasive
compound on the mating surfaces might improve their flatness and fit, and
thus the heat transfer. Maybe something like jeweler's rouge? And I think
you'd probably still need heatsink compound.
I think David is right. The closer the fit, the better the heat transfer. If you
were only doing a few parts, you could lap the two parts together -- put a very
fine abrasive between them with a drop of oil or water, and rub them together to
take the high spots off from each.
But that's too tedious for a Curtis with dozens of parts.
