Dry methods for bubble hash (crystal) making:
Flat Screening (ancient way) | Drum machine (Pollinator)
There's some debate about the wet vs. dry issue. Here's the story - Opti says: Wet methods like the Bubble Hash Bags systems are more efficient at getting ALL the resin glands off the pot and can achieve the highest purity. The dry methods, including the pollinators, are more adjustable. If you put great source material in a dry system, you will get the highest grade stuff in the first few minutes of tumbling - this is grade A crystal. If you run it for 15 minutes, you'll start getting greener and greener (more contaminated) KIF.
If you are doing large amounts, then the wet method using a washing machine is the way to go! Dry on the other hand is really great for getting the gourmet hash out of great buds!
Major Methods for Making Bubble Hash (Dry):

Flat Screening - Sifting
Flat screening removes the trichomes by rubbing the skuff over a fine steel or silk screen. This is a very simple process but the quality of hash is very dependent on the skill and patience of the maker. The principle behind this method is that the trichome heads are of a fairly consistent size, so that when applied to a mesh of the appropriate size, the trichome heads will pass through but other plant matter will be left behind.
You'll need a flat screen. Screens can be bought from printing supply shops for $10 to $30, depending on size, or you can make your own. To make your own, fasten four pieces of wood together to form a frame, then glue screening to the bottom. Small hole screens are best, between 125-137 lines per inch.
Flat screen hash generally contains more contaminates than any other method. However, it is the simplest and cheapest way for the home gardener to make use of scraps.
Drum machines - The Original Pollinator
A drum machine is cylindrical, like the inside of a clothes dryer, and is electrically powered. Inside the drum is a screen which the skuff is slowly tumbled against. It's much the same principal as flat screening, except the drum machine tumbles the skuff instead of rubbing it. Drum machines can be bought, or if you are handy, plans can be found to build your own.The most popular drum machine is the Pollinator, developed by Mila, a pioneer of Amsterdam's hashmaking community. She has developed machines in a variety of sizes to handle different quantities of product:
The drum screen should be 125-137 lines per inch like the flat screen. Lightly fill the drum with dry skuff (remember not too dry) and turn machine on low. Let it run from a few minutes for up to one hour the shorter the time, the more likely you are to get only gland heads. You can collect the hash-powder and then run the machine again to produce a lower grade of hash. Depending on the quality and quantity of original material, you can do this a few times, with each grade containing more contaminates.

Mila's marvelous machines:
Mila Jansen, owner of After the Harvest and Pollinator Co in Amsterdam, is an innovator in this field. She has invented two ingenious machines that collect resin powder.
The first is called The Pollinator and in many ways it resembles a front-loading washing machine. Dried plant material is placed in the machine, which then spins. There is a 150 micron screen around the perimeter of the inside and the resin simply passes through, to be collected with ease from a resin trap below.
There are different sized machines, and the smallest will fit in a refrigerator. The cooler temperatures allow the resin to be collected more efficiently.
The less time spent in the machine, the higher quality the powder – this is the golden rule. The first sample taken at 2 minutes is very pure, as only the heaviest glands have fallen through; very little vegetative matter has made it through the screen. The longer the machine spins, the more vegetative matter falls through, thus lowering the quality of the resin powder.
1. Before using the Pollinator machine we highly recommend that you put your leaf material in an air tight bag which is then put in the freezer for two hours. This will harden your plant material, making the sieving process considerably more efficient.
2. Now that leaf material is ready to be pollinated you can open the lid of the Pollinator and then lift the drum out. Lift the drum out by the side with the motor first and then lift the other side of the drum.
3. Now you have removed the drum you can open it to insert your leaf material. The lid of the drum is magnetically attached so you may need to firmly pull it off. Make sure that your plant material consists of only small leaves and flowers and not any stalks which may damage the screen of the drum. Close the lid of the drum and then put the drum back in the Pollinator.
4. You can now turn on your Pollinator for the first turning period. We recommend that a first session of between 2-5 minutes in order to collect the purest quality of fallen resin glands. Using a kitchen timer is advised so as to keep track of the turning sessions.
5. Now all you have to collect your crystals and enjoy a great smoke!
