If you are going to build one of these for use with solvent paint: Be very
careful what kind of fan you use! Some fan motors could emit sparks which
will react very badly with the solvents in paints, possibly destroying the
article you are painting, along with anything in the same room!
You need a totally enclosed fan motor with a squirrel cage fan - try an
industrial supply house...
