FYI:
A fellow modeler sent me this email about the homemade static grass maker:
A couple guys in our group built the static grass applicators from Patterson’s article. They work OK on the really short static grass, but if you do a side by side comparison with a ‘real’ applicator, like the one from Noch, the difference is staggering. For starters, the Noch unit has 10x the power, and will easily make ½” fibres stand straight up. Because it is more powerful, it is also much faster. I guess you get what you pay for…
