Great idea - - - - thanks for confirming your technical terms!!!
Hmmmmm - - - - wonder how that blower would last on a serious furnace boiler?
(I wonder if replacing the bearings and perhaps stabilizing the impellor re: the housing would be enough to transform the blower from an occasion use thing to a serious long term use capable item - - - hmmmmmmmmmmm.)
The impellor is mounted directly onto the motor shaft which means it uses the motor's bearings,... which are now ball bearings with the new, larger motor. Another problem I ran into using this leaf blower was the clearance between impeller and housing was over 5 millimeters. I added plastic sheeting onto the inside surfaces of the housing to reduce the clearance to about 0.5mm,....thereby increasing the volume and pressure of the air output.
