Nice job on the blades Bruce ,
Is this a hand crank fan or motor driven ? and did you make all the fan blades we are looking at or just add new ones between the old blades ?
I am wondering will this be spinning clockwise if so wouldn’t the blades have produced better draughts if the blades were facing the other way ?
Excuse all the questions just trying to understand a few things in my tired old head as a the fans I have used in the past have had the blades facing the other way , apart from the paddle fans that are just a flat blade .
