Been awhile since i did a how to, but every day i see people with questions on hash making. There are several methods of hash making which include:
Dry sieving: Using a tumbler
Carding: carding material over a screen
Ice water filtration: Using filter bags with ice and water
I'm disabled with limited use of my hands so over the years using my Bubblebags or using screens became out of the question. In 2004 i looked into dry sieving and making my own tumbler. With tumbler plans found on the internet i set out to find the parts needed. It quickly became obvious that after looking at purchasing a motor.......and not a 1rpm rotisserie motor which i consider too slow, that yes i would save some money but factor in time, tools, and how it would hold up. I decided too just purchase a tumbler.
Looked at several companies including pollinator, tumblers were a bit pricey. I finally decided to buy one from OKIEF.COM
which was right within my $200 budget which was $150 before shipping. This purchase later evolved to them marketing my oil tubes jyi.
Long story short this tumbler has paid for itself 20x over if not more. However if you are handy with tools and have the time by all means build your own. The purpose of this thread is to give people a basic knowledge of dry sieving and answer some common questions.
How much will i yield? Using trim expect up to 5% return, using buds 10-15% return. I have achieved 15% once with ultimate moonshine from JLP.
The number one misconception I’ve seen is throwing any leaf off the plant into a tumbler will get you something.........by far not the case. The kief that we seek ,which when pressed is hash is from the capitate stalked trichomes on the outside of the leaf surface. These trichomes (triches from here on out) are what give the buds the chrystally appearance. Let me repeat, the only thing that will be removed from the plant are the VISIBLE trichomes on the leaf surface.
With that said lets get started.
When harvesting a plant, i use 3 boxes. I've found the shallow boxes that hold 4 6 packs of soda to be perfect.
1st box (Garbage): Large fan leaves, stems, anything that does not contain visible triches.
2nd box (Trim): Any leaf that has visible triches that will not remain on the bud after manicuring
3rd box (Buds): After manicuring the buds go here.
1st box is trash and if you live in the country gets burned. Never put this in your garbage at the street. Some people compost it or you can cut it up fine and flush it.
Your trim to be tumbled needs to be very dry, almost crispy. I dry a minimum of 2 weeks but prefer 3-4 in the open air. If i use my bud dryer (in gallery) i can cut that time in half. Trim to be tumbled does not have to be cured
.......does not have to be cured....does not have to be cured. Got it, good.
To make the heads of the triches more easily removed, we need to freeze it. A minimum of 2 hours but the longer the better. I prefer big glass pickle jars which are air tight and easy to clean. The very best freezer i have found is a deep freeze or the smaller 3 foot high freezers where the actual racks are coils. When i remove the jars from this smaller freezer, i have to wear gloves........and deffinantly don't stick my tongue on the jar LOL.
The smaller jars are great and can just be opened and poured directly into the drum.
in these pics you will see some popcorn buds....these need to be broken up as much as possible. Any trichomes within the bud will not be removed. We want the most leaf surface area as possible for the best result. To avoid knocking too many trichomes off before tumbling , i partially break the buds up, tumble and really break them up good for a second run, resulting in a lower grade.
We also want to add rubber balls to agitate the material and help press the leaves against the screen.
If you are using a drum with poly screen, all sharp objects such as stems need to be removed to prevent damage to the screen
I recently got the 110lpi stainless mesh drum from okief which is ALMOST indestructible, and i can also tumble stems in it. Why would i tumble stems?
Some strains produce trichomes on the stems of the plant. The particular strain i am using is Astroboy which has ALOT of triches on the stems.
Now lets get started.
I only fill the drum half full to allow more tumbling action. Tumble for 15 min, stop let everything settle for 5 min, collect, tumble again for 45 min. easy enough?
Also an eye loupe is an important, necessary, and cheap piece of equipment.
Eyeballing a leaf after tumbling will still look like it has trichomes. If you look under a loupe you will see over 95% of that is simply headless stalks......this is good
OK here's the good part:
Used 2.5 oz of trim and popcorn buds from 3 plants.
70g trim turned into 2g of 15 min run primo kief = less than 5%.Which was expected.
I do love the removable collection plate in this tumbler. I think it's vinyl but not sure. The rotating of the drum creates a static charge on the plate and the kief stays put. I can tip the plate vertical without it falling off.
We’re not done yet. I’ll do a second run and really break up the popcorn buds. I place them in a small food processor to break them up but donot make it a popder
This will be refrozen and run again.
This thread is a work in progress and I’ll update the second run shortly.
