Long project finally done. At work we have these 30 and 36in fans and we have a lot of them. Life without them working in a warehouse in Florida is unbearable. We recently went through a whole system upgrade and some of the old ones where reposition into areas the didn't have them. I really thought I could get one but it didn't work out as planned.

So I had a small of these motors laying around.
I had this fan blade and cage also.
So how do I adapt a bandsaw motor to a fan cage not meant for it. Well I needed a adapter but what to use???? Well I used a circular saw blade.
So I drilled holes and mounted the motor to the blade then blade the the cage. The motor had small hump
So had to space blade off the motor so I used some washers and nuts.
I then had to drill out the fan shaft and used washers as spacers.
Here's what it looked like all finished. ( minus paint. LOL)
Ok let's see fan blade spinning at 1725 rpm this should be great. I plug it in and it works!!! There's no vibration but output isn't what I hoped. I have smaller fans like this so it somewhere between ones I have and work ones.
I started to think ( not good idea) if I bend blades like ones on the ceiling that it would push more air ( I'm have no ******* clue I'm winging it)! So I tilt blades and make sure all bent to same angle and all in line. I put shroud back on and get ready!
CONTACT.... LOL Well apparently if you put enough angle on a spinning fan blade at 1725 you can create enough force to propel a fan across the garage. NO I not kidding I had it on the cart and it flew off the cart onto floor and across the garage into the storage wall!
PLAN B.
I scaled back the angle I used to between what I did and what was original. I also decided to strap in down to cart.
I'm thinking of mounting it somewhere similar to what's at work. Summer is here and this will sure help make it alittle more tolerable out the in the garage. [emoji482]
