Four New (Old) Motors

[Alden]

I picked up four motors at an estate sale today, and I'm wondering how to best put them to use.
The RPMs are - 800, 1050, 1100 and a buffer with two wheels thats 1700 .
What I want to do is set up buffing wheels, build a sanding disk, and drive a long slack sander.
What recommendations do youse guys have for assigning a motor to a task ?
I'm thinking the 1700 to buff Tripoli and White Diamond.
The 1100 for Carnauba.
Does it make sense to set up the 800 just for a final buff ?
Will the size of the wheel (8") change the RPM my motors are listed at ?
I dont know what to do with the 1050 yet.
There were two other motors at the sell, neither one had any info on speed/horsepower but I thought about going back for them for $5 each.
Any thoughts ??

sounds about right. I think i remember reading that 800 is final buff speed, then you could use the 1050 for slack sanding. As long as you have room to mount all the motors.

I have a thought...go back and buy those other two for me!

Nice score.

I dont have much space, but I'm building the entire workshop, toolbenches and all from scratch. I can easily fit the motors in somewhere in the plan.
I wasnt sure if 1050 was too fast for the sander, or too slow of a high speed if I set it up with step pulleys.

Tyler, I'm on it.
If you'll get out towards Dallas in the next year or so, I'll store them until then. After 12 months, I'll need to start charging a small storage fee
Really, If you want em, I'll fetch em.
I've sure been blessed in my tool aquisitions to date !

I am interested, and my in-laws live in the metroplex so I'll be that way some time or another.

Do you know if the motors are enclosed or open? If they are open, I'd pass, but if they are enclosed, I'll take 'em no matter what speed they are.

As for you motors, the slow ones you got are hard to come by. The 1050 that you are unsure about should be a good higher-grit wheel for some finish sanding. Or, as has been previously mentioned, a slack belt sander.

Do you know if the motors are enclosed or open?

And the total noob answer is;
I didnt pay attention to wether they were enclosed or not!
I dont even know if the ones I bought are open or enclosed!
So much to learn, so little time.
I'm sending you a PM

I dont know what to do with the 1050 yet.

The buffer runs at the right speed for tripoli and white diamond with 8" buffs - at least for the way I work.

I prefer to apply carnuba at around 800 RPM with an 8" wheel. This is also the final buff with a super soft 4" wheel.

I like 1800 RPM for shaping, and for sanding up to about 200 grit. After that I prefer slower speeds anywhere from 800 to 1200 RPM. Slower speeds are really good for higher grits.

EDIT: to add that depending on your drive wheel, any of those motors will work for a belt sander. And since it's just wood, HP doesn't matter much. If you were grinding metal that would be a different story though.

[Alden]

Thanks Kurt !
I'm going to put off the belt sander for a little bit because I dont think I need one right away. I'll set up a shaping wheel, and I should be able to do most everything with that for a bit. When I build one, I want the speed to be adjustable.
Appreciate the info

I want to buy the 800.
Want to sell?

I doubt I'd sell any of them right now anyway.
