I know this thread is old but I have to let ya know that if you want kief all you have to do is get a 220 micron bag from whacky bags dot com and some dry ice. Break up some dry ice, put it in the bag along with some trim or bud. Let it chill for about 30 seconds and shake the bag over a glass table. You will be amazed on how much kief falls out of the bag onto your glass table. Stop shaking once the kief starts to turn a light greenish color. Kief has a tan look to it. Good luck! And aslo its much quicker and cheaper to do it this way and you get all the kief off your weed.
Saggitaur Reviewed by Saggitaur on . I want to make a kief tumbler I imagine converting a rock tumbler. Or perhaps getting a small electric motor and pully and see if I can make one from scratch. I have access to a CNC and all woodworking equipment. Has anyone heard of a tumbler to separate kief? Has anyone made one, or better yet have plans? What mesh screen is best for separating kief? I understand that silk screen material is best, but there are many different mesh sizes. I searched for this but there is very little info, at least on tumblers. Rating: 5
