Hey Oldhaole, that's nice! Could you maybe make a pic tutorial of building one? I like Weezards idea too. Maybe even multiple mirrors! Or maybe make a frame that would accept different finenesses of screening, so you could just slide one in and out and slide another screen in... I've been thinking along the same lines everytime I make it...."this is too much like work!"...and I was drawing one up based on a drum shaped tumbler, kinda like a rock tumbler/polisher. But it would have to have different drums of different size screening...I have acces to lots of little motors and gears and pulleys and such. I was gonna use an old sawzall (reciprocating saw) to make a shaker too but it turned out to be too fast and powerful....LOL! Shit went everywhere! oooops! But I think I like your design better! Somebody over in Amsterdam (can't remember who it was now...) had made one and it looked so nice....just put yer stuff in there, flip a switch and ck it in a little while and scrape up the goodies! But I have a palm sander sitting around doing nothing since I quit working on boats and I think it shoud be utilized again now...Another guy, supposedly the "king of hash", or "best hash maker in the world", again, over in Amstown, says you should do this at exactly 41 degrees F and your stash should be the same temp or colder...supposedly the trichs snap off easier and cleaner....so I was gonna make one that would run inside the 'fridge and I think maybe a slightly smaller version of your design would fit in there better. Have you ever done this at 41F or do you just shake it at room temp? Thanks for posting that, I am now inspired to go ahead and build some kind of labor saving device for keif sifting! Now where the hell is that tape measure of mine???
