as promised here's my blower modification / "upgrade" - basically I took the motor and fan out of the hair dryer and along with a reducer for vacuum cleaner hose made this... Works awesome! I was thinking about adding a potentiometer to be able to adjust the speed - but so far it worked so good I don't think I'll need to!
