Nice unit.   This is built sturdy and should last forever.    Unfortunately I dropped motor unit while installing and crushed the plastic fan.    I will epoxy it together and see if it runs  without shaking.    You did a wonderful job on the parts no sharp edges and even the drilled holes have no burs.    You must have been a machinist or an engineer or just one talented guy.   I am not used to seeing quality with everything made in china now a days.
