I would imagine you could do it morrocan stylee by securing with some rubberbands over a big metal bowl and stretched tight.
I've seen dozens of photos of those Maroc style dry sifting tubs with mesh stretched over....but it could be so much better to work with if they had sides so the plant material doesn't just slide off the edges of the tub they use. Bubbleman's dry sifting screens are not just screen printing frames with the right meshes attached, they are purpose built for dry sifting, the top frame sides are high so no plant material spills over, each frame interconnects with the other to ensure no slippage, the bottom frame mesh is 1/4" above the bottom of the frame so the small particles pass through more easily and the top screen has tough S/S mesh so is virtually unbreakable...these are on special now at Aqulabtechnologies.com
Happy Hashing!
