OK living in Florida gets hot during the summer months. So a large fan would be really helpful. My Dad found the fan blades and shroud at a yard sale. I welded 1"x 1" by 1/8" square tubing frame together to build a frame. Added 3 wheels to the bottom to wheel it around. Than the motor base was built and welded in. Bought some horse fence and made guards for front and back. Rip down some plywood to build both sides and top. Now the fan sits on Mom and Dads porch and keeps them cool all summer.
As we have seen in other work your care and quality are indisputable.
Congratulations.
Just an idea to improve your project, add a humidify to lower the temperature so you can use as an air conditioner, improving air humidity.:idea:

My dad did that later on to his second fan but thank you and yes a bit of water helps a lot.Quote:

About 36" blades on that fan one down at the shop is 48.Quote:

Thanks Vernon! I've added your Shop Fan to our Miscellaneous category, as well as to your builder page: Vernon's Homemade Tools. Your receipt:

Hi Vernon, what's the rating on the motor driving the 48 incher?
pfff, in my area, I am more trying to dry the air :headshake:
Nice fan !
DIYer I like to see the fan run at 172.5 RPM so if your motor runs at 1725 Divide that by 10 is 172.5 rpm can run it faster but I hate the noise. Just want to move air not chop at it.Quote:

Finally! I have 3 such fans, one needs a motor but mechanically all are fine. Wanted to build these enclosures a long time. Until now, had puzzled on what to use for screening. Never thought [unaware] of agricultural material, other fencing varieties are flexible. Saved me some RPM testing too, will copy 172.5 recommendation.
Do your large fans 'walk' out of position? 3 wheels [1 crazy, 2 straight] is correct, too many uneven surfaces, 4 usually unstable. Kick-out casters would work too, for parking.
I have a 48 " er with a 10" pulley but no motor that I have been hoarding for a few years. Without an actual shop I haven't needed it It is just one of those many things I own that I see a potential use for someday so wont get rid of it.
when I finally do get around to pressing it into service I will either mount it high up in an end wall to serve as an exhaust fan of do Like the OP did to make a floor model out of it
I had a floor model once that originally had the 1/2" hardware screen front and back for the safety screen but there seemed to be a significant amount of restriction to the air flow plus the dust build up on the back meant frequent cleaning was required. One day I replaced the rear screen with 1' Poultry wire The motor ran cooler less frequent cleanings( almost never) plus a slight increase in flow This encouraged me to replace the front screen as well. Unimaginable hjow much better the circulation od air was plus a significant reduction in noise it even got rid of the constant hum of the motor
I took a closer look at my 48" fan today I thought it had a 10" pulley but after measuring it it is a 12" cast iron A section size the Curvature of the blades indicate it was an exhaust fan This would not be a problem as I could just use the motor side as the output but that would mean I wouldn't be able to add moisture saturation media for evaporative cooling without subjecting the motor to a wet environment, should I desire to do so. However I could probably turn the blade around to allow for air flow through evaporation media to keep the motor in the dry.
This would be something for others to think about should they decide to construct a shop fan like the OP has done
