Great vibratory sieve

Wowza! This sure works good!

I saw a picture of a vibrating sieve system called a Resin Reaper, which impressive claims were being made for, but decided to forgo the $450 price tag and throw something together out of available parts to check out the concept. In short, it works damn good!

Here are some pictures of the prototype, using a palm sander for the vibrator.

I tossed in a hand full of sugar leaf and ran it exactly 3 minutes to produce the pile of kief shown. I used a 130 micron stainless screen and microscopic exam shows it is primarily collecting mature heads.

Five of us sampled the kief and all declared it primo.

Here is what I did:

GENIUS! This gave me a few ideas I'm going to work with tonight =]

:hippy:

Ok, prototype finished and the performance trials were run.

As you note the Lexan has been replaced with a sheet of 1/2" Nylon, because the vibration was cracking the Lexan. We also added door sweeps to keep fine particles from being ejected around the edges of the plate.

Lots quieter with the nylon plate and adjustable rubber feet.

We also changed the screen tensioning design.

On two runs, it produced about 1% high grade kief by weight in 2 minutes of running frozen cured sugar leaf. Microscopic examination shows it to be primarily mature resin heads and an examination of the dregs show it still has resin, but mostly stalks.

Sorry I don't have extension tubes for the camera yet or I would send you close up pictures.
