If you could fine a 2 or 3 speed motor that would be ideal.

Looks like your headed in the right direction.

Yup don't build it like the one I did whenever you had to use it, it had to be chained down otherwise it took off and ran around the yard and then ya worked up a sweat just trying to catch the dam thing... unless the extension cord ya used that day happened to be a short one

Don't know what the ratio was but was 2-1/2' small pully top pulley was 10"
separated by about 30 inches apart 54" fan from an army base off a chiller cooling unit... put a 2hp 1735 rpm motor on it.

turn it on in the shop and everything became looking like something out of a Jumanji movie... monkeys and the ex flying around on brooms and shit!

My suggestion is spend the $100-$150ea for decent stand-up fans and be done with it. My small shop has 3 fans in it so even 1 fan for you isn't going to cut it. Sell that fan at your first yard sale or put it in the "project" pile.

NOW is the time to be buying fans before the summer heat commences and Chinese inavailability affects prices...

PS: the same goes for window A/C units...

With speed comes noise,and you can't weld anywhere near the fan.
If your trying to dry a wet floor,you need high fan speed.
Now if your going to mount this fan way high in a wall and have it suck out,high speed will be better,except for the noise.

I was assuming (bad thing) that you were planing on mounting the fan on a cart with wheels so it can follow you around the shop.

Ceiling fans would be a better choice.
A friend had a old worn out wood airboat prop mounted on a stand,it turned slow but moved a lot of air,and it was quiet.
That prop may have been 80'' .
That's the plan. Mount it on wheels. Ceiling fans or air conditioning in the shop can come later.

I will say it seems with the big 6" thick slab I have it takes a bit for the building to get hot inside.

Yep,the slab is cool now,but soon it will be hot! Keep the sun off the floor and you can keep it cooler.

Before the hurrican blew my roof and all the skylights off my house floor would get hot under the skylights.
When i rebuilt the roof i put in dormers,the light it better and the sun is not shining right on the floor,the floor is much cooler.
Keep the doors on the sunny side closed when you can.

Building a box. Using a table saw motor for power. The rpm is 2× but I already had the motor and think if I use a pot to control speed I'll be fine.
