I’m a mechanical engineer. You’re going to lose virtually all of the reason for having a fan blade once you make it so very flexible. It needs to have strength to push against the air or
the air will instead push the blade … out of the way. It might be quiet but that’s because no
air is moving.
If you truly want to try something , as an experiementer that I’ve had excellant good fortune with is this:
USe a CLEAN electric leaf blower and put it on either 12 volts DC up to about 25 volts DC and
take off the long long snout if you can. It’s in the way.
The squirrel cage type motor and the low speed at 12 volts means it’s a directed but very quiete flow of air. I’ve made two of them and they work much better than any fan I’ve
ever owned. I think I like the quiet and the fact they put air where you want it.
It should be about 8 feet away.
Remember you’re not running them on 120 V ac. If you MUST then try using a dimmer but you will also need to put extra load on the dimmer with the fan to make it work properly. Or it
will run too fast.
Many places sell refurbed leaf blowers for under $15.
Ok. More about these.
Never needs oiling means they are sintered bearings. These wear out rather quickly. Even faster since the load, the fan, is not well balanced. how could it be with floppy wobbly blades?
If you DO want more power from the fan blades try this: Put some weight on the ends. USe
something very sturdy like:
Very very strong staples with a heavy bit of plastic… AND EACH of the 3 MUST BE IDENTICAL… OR it will wobble and not work.
You would measure out a fixed amount of thick adheasive and do the same thing.
It will be nearly impossilble to make it balanced. Maybe what you should do first is see if you can make duplicate blades AND attach them if necessary.
These are a toy to deprive you of your money. Novelty is the main thing that people buy thigns for in this society. If you lived where food was scarace you would not ever think to buy
