how to make a grinder for weed？Why spend your hard-earned money on an expensive grinder when you can easily make one at home? It’s actually quite simple to make a grinder for weed, and all you need is a few household supplies.
A grinder is a device that breaks up the cannabis flower into smaller pieces, which makes it easier to vape. There are many different types of grinders on the market, but they all serve the same purpose.
In this article, we will show you how to make a grinder for weed. This grinder is easy to make and only requires a few tools and materials. But before that, if you are outdoors or traveling, there are not so many tools to make a grinder, I will first teach you how to grind weeds without a grinder
grind weed with a credit card
A lot of people ask us how we get our weed so finely ground up for rolling joints. The answer is simple: a credit card! Credit cards are great for grinding up your cannabis because they're thin and flexible, which allows them to move through your bud more easily than other tools like scissors or knives.
To use a credit card grinder, simply place the desired amount of cannabis on a hard surface and press down on the weed with your thumb or fingers until it is finely ground (but not so much that it turns into dust!).
In addition to being convenient, credit card grinders are also very portable — they can fit in your pocket or wallet — making them very easy to take with you wherever you go. If you're going camping or traveling somewhere where smoking isn't allowed , for example, having a good credit card grinder on hand can be really helpful!
rolling paper and a coin
You can also use a rolling paper and a coin or bobby pin to break up your buds. That's how I used to roll joints back in high school when I didn't have any papers on me (and even then, I always had at least one).
If you want to go even more low-tech, try using two pieces of fabric one on top of the other (a towel will work) and rubbing them together until there are enough small bits for you to smoke.
with scissors
Speaking of simple, nothing beats the traditional scissors method for a quick do-it-yourself grind. I like to use my trusty Fiskars; they have never let me down.
I lay it out on the paper, and then we can start using scissors to cut the cannabis flowers into pieces. This method is clean and simple— just the way I like it. The secret is having super sharp scissors that slice right through the gooey stuff without any effort at all. Well, it does get a little sticky, so to keep my hands clean I usually throw on some gloves.
This easy technique may not be the fastest way to grind, but it certainly gets the job done in a pinch when you don’t have a cannabis grinder handy.
I like to design a high-efficiency, multi-chamber grinder after the grinding portion is done. I made a four-layer assembly here. From top to bottom, they are the Grinding Chamber, the Collection Chamber, the Kief Catcher, and the optional Pollen Press. To segregate particles exactly, each layer employs holes and meshes of varying sizes:
In the Grinding Chamber, the herb is first sliced into small pieces. The filter holes are precisely placed so that medium-sized pieces can fall into the Collection Chamber while bigger pieces are kept for more grinding.
A small mesh of 0.15–0.25 mm stainless steel is attached to the bottom of the Collection Chamber to trap tiny trichomes.
The Kief Catcher below catches all the sieved kief. It uses vibration, rotation, and gravity to get the most out of the kief and give it a better taste.
Structure of the grinding chamber and design of the filter hole
To make the Grinding Chamber, a single metal plate (0.8–1.2 mm thick) is rolled into a cylinder. To keep herbs from becoming stuck, the inside wall is polished smooth. Laser cutting or stamping makes a lot of filter holes in the wall of the cylinder that are 3–5 mm in diameter. The holes must have the right size and form for the grinding teeth. If the holes are too big, the sieving won't be as accurate, and if they're too small, they will get clogged fast. It is possible to cast or stamp grinding teeth out of aluminum alloy or high-strength stainless steel. Each tooth is held in place with a tiny stud and nylon washer during assembly. This keeps the tooth 1–2 mm away from the edge of the nearest filter hole, which helps keep the cutting sharpness while avoiding over-grinding.
Setting up the collection chamber and mesh
You can attach the Collection Chamber to the Grinding Chamber with threads or snap-fits. The bottom is carefully welded or riveted with high-strength stainless-steel mesh. A mesh size of 200 to 300 mesh (around 0.15 to 0.25 mm holes) is common. Leave a 2–3 mm mounting flange around the mesh frame, and use ultrasonic welding or epoxy to hold it in place so it doesn't move as it vibrates. There is an O-ring silicone seal between the two metal layers to keep them from leaking or jamming. This also makes it easy to take apart for cleaning.
Design for Kief Catcher
The Kief Catcher is a shallow, slightly recessed ring-shaped tray (like a little bowl) that collects all the fine powder that goes through the mesh. The height of the tray wall is 5 to 8 mm, and the inner wall is tilted 3 to 5 degrees to guide the powder within. The Collection Chamber's interface also has fine-pitch threads (around 1 mm pitch) that are strong enough to hold up to shear forces but easy to screw together.
After we've made all the accessories, You can also add small NdFeB magnets (2–4 per interface, 0.5–1 kgf pull each) to each mating surface in a symmetrical way, or you can add quick-release spring clips to make sure they don't come loose. To lower the risk of cuts and stop powder from building up and jamming the mechanism, all metal edges should be chamfered. After putting everything together, do a spin test with no load to check the speed of rotation and how well it handles vibrations
