Rosin Press, Bubble Hash, et al.

3.4 grams.. Up to 18-20g at most of Durban Poison and Gorilla Glue x White Widow. Forgot to picture the flattened 'puck'. It was quite thin. Well, first try with a rosin press. DIY 20T press with a 4x7 platen kit. Has a insulator, but intend to put a chunk of a leather belt in there next time. I could feel a little warmth above top plate. The bamboo on the bottom worked well. Couldn't feel anything on arbors. I may have warmed up the buds under initial light pressure a bit too long as i ran to get the camera... FFS, what a horrible excuse. Genuinely embarassed. Probably should have bought the 3x6 bags vs the 4x7 bags. The back didn't pinch out, so no problems this time. Need to pack a little emore into the back. Forgot to weigh what went in. A 32oz mason jar of small-ish nugs has ~14 grams left. So, 16-20grams is a good guess for those nugs. So approaching 20% yield or a bit above with buds harvested in.. i think early august. There were two types of buds in this. Not optimal, but meh. The durban poison side spat out more, i think, but also a bit more moisture in those buds for whatever reason. Fingers get sticky with the GGxWW, but with DP it's a thinner-spreading oil is best i can describe. Folded the parchment well enough. Some lost bits along edge of bag. Cut a bit too much off top flap and have to clean the top platen a bit more than i should. Summary -- I have a much better idea of how to do this know after the first attempt. I can fill the bag a bit more to shorten up width - bump up to 30 grams and see what happens. Wrap parchment more tightly, but a little room for squish. Reduce amount of time for intiial pressure and a bit of heat (don't run for something stupid while doing it!). Increase pressure slowly like this time, but much better idea of what to feel. If i crunch it at end, i may try to separate it before doing so - maybe, scrape it down a bit or anything alike. I have abunch of frozen trim and larf, but not sure about the water content... probably evaporated a bit by this point. I'll be adding more weeks with each press. Any expert advice is always appreciated. Thanks to @the_canna_scientist for some tips and info. As well as numerous sources on the internet. Nearly as many contradicting statements as anything else. If i had a drill press, i'd make the platens myself and save a bunch of money. As it was, a 20T press with 4x7 platnes is about $450-500. These have dual heaters in both plates - 300x4=1200w, must be 10amps or so. They heat up quickly.
