BTW, the baffle is made from 1/8 tempered hardboard

Someone E-Mailed today and asked what the baffle itself was made of.  It is 1/8" tempered hardboard.  This is smooth both sides, and is quite slick.

Due to the nature of the material (dark color, produces lots of fines when machined) hardboard also works great for testing separation efficiency.   ;D
