How To Use A Weed Grinder
At first, you may feel the grinder resisting to rotate, but within a few turns that feeling will disappear. Once it feels smooth and easy enough to rotate the top lid, you'll know your weed has broken up. 3. Tap and Collect . Tapping the top lid of the grinder before removing helps prevent any excess weed from spilling out when you open.

Bowl Gouge
The 40-degree grind 1/2" Hurricane gouge does a lot better on bowls than it does on spindles. I sharpened that gouge using Ron Brown's 40-degree jig and resharpened it at 40-degrees using the Carter and Son settings using a Oneway sharpening jig and there was little to no difference in the finished product.
Faqs
The planetary ball mill features a bowl and a turntable that rotate in opposite directions. This setup causes the grinding balls inside the bowl to move in a complex, multi-dimensional pattern. The balls not only roll along the inner walls of the bowl but also strike against each other and the opposite walls, generating high-impact forces.
