Only just noticed this thread. Thanks for the inspiration Ester and thanks to DSW for his secret technique from the other thread.
My thoughts:
Somehow create negative charge just strong enough to attract the lighter contaminants and stalks whilst leaving the heavier resin heads, much in the same way as the salt & pepper static trick from schoool science.

^^SSSh piff , sounds good, just need to do some more experiments...

Or alternatively, place farmer's grade sift on 70u screen and place negatively charged material underneath the 70u screen, sucking the contaminants and smaller heads through the screen but leaving the larger trichome heads on top?

Lots of posters over the years have suggested this and no one to my knowledge has has much success in cleaning up rough dry sift into 99% resin. So negative charges used to clean up contaminated dry sift is probably not the answer.
But no matter which way Sam does it, keep in mind that he only yields 10% of the resin on the plant, so I'd suggest the answer to Sam's secret dry sift method will be worked out by someone who starts their experimentation with that fact in mind and it's also likely that it's a very simple technique, much like DSW's method.
I start with trim and small buds, basically "hash from trash" so my yield is not even 10% and cleaning up rough dry sift is exactly what i do. The technique is simple and unlike Dsw's method you can do larger amounts relatively quickly..
