I had really good luck with the tumbler. All it was, was a drum style humidifier with the foam pad removed and a silk screen wrapped around it with big gear clamps. I cut a disk and covered the one end. I made a lot when I had access to fairly large quantities of Mexican brick (not to my liking for smoking but sold tons lol). Would let the shit tumble for about 3-5 days (if you've polished rocks you'll understand, it's slow lol) and it would fill the tray. I put it in a baggy with Teaspoon of water for every 3 ounces of dry kief. Heat it to 120 then press it and most times I would get a black to very dark brown hash that was unbelievable good. The more you rolled it around before pressing the nicer the color would get as well as the aroma. I only used buds though and have never tried shake. I make glass now
, not for the taste mind you lol, it just gets me very high lol.
