Based upon a CHAIN BRACKET design I saw but can't find anymore (If you are the original autoher, please contact me to add your info).
My mods:
Tested using a 10x10 chainn and a 50mm radial fan.
This air assist is not as powerful a shop air compressor, but works fine to keep smoke away from the cuttig line.
