gw, you neglected to mention the idea of rock tumbling sticks with fractured construction sand to "sand off" the outer trichomes, then sieve the sticks out. repeat until sand is laden with trichomes then extract the sand.
i got a rock tumbler explicitly for this purpose. must get to this experiment soon.
Good point! As the material that we are seeking is on the outside of the sticks and stems, if we tumble them with clean sand without bothering to pulverize them, we can extract the resins from the sand later using a solvent.
You can use a rock tumbler or just put sand, solvent, and stems in a glass jar and shake. Process batches of sticks and stems through the same sand and solvent before extraction.
