Would love to hear pro and con
Some pictures showing parts.
The addition of sound on start-up would put it over the top..seems more electronics will be required.
))))))I think Ms Patti is gonna be pissed about the smoke.
To make it blow down , it has to turn in reverse or you have to be looking at the back of the blades. I have a 2 blade prop fan from Lowes that has a very authentic hum and most folks assume it's real. Also comes in 3 blade.
Dan, since you have a couple of wood props, and great metal work skills, this would be right up you your alley.
I built one that worked great. Recently moved and brought it with me intending to install in my new house. Unfortunately the attic wasn’t suitable. I used a 1/2” aluminum plate and attached a motor, heavy duty gear reduction unit, and two one inch pillow block bearings. Then ran a long 1” steel shaft down thru the attic into living room. The prop was pitch adjustable so i was able to have the painted side down and the airfoil correct. I’ll try and post pictures tomorrow.
...Does a fan really need to blow downward? I think "yes" on an open porch or large space, but perhaps not in the average room. They're really air circulators. Flow upward in the center of the room and down along the walls isn't a lot different from down in the center and up along the walls...
Wonder how effective a propeller would move air turning backward?
Wonder how effective a propeller would move air turning backward? I've got two old wooden propellers that I've thought about adapting as ceiling fans, but won't do it if I can't see the front of the blades.
