If you want 3FFFG powder just use hardware screen from the hardware store.For 2FFG I use the handstranders
from walmart kitchen supplys.I make a pressing piston & sleave for pressing pucks.I looked up Hobby to see what charcoal
there sending in there kits.It is just air float & not black willow.
Air float is OK but you will never get the performance as with Black Willow.I think I have a post with pic's here on the
thread some where on corning.For get corning for now & work on the screen powder for now.It's like cooking, not
hard, just takes a little learning curve.
