What Can I Build

I just got a very good 6 HP, 220Volt, 3460 rpm, air compressor motor but have no idea what I could build for my shop with a motor this size. It is the same physical size of a 1 hp motor but 6hp is a lot. I have the arbor to build a buffer and want to build a horizontal disk sander for use to flatten handle material and making folder parts but I would be worried at that HP and RPM. I have no means to VS it so it will be a one speed motor unless someone can tell me how to slow it down. I already have a belt grinder and don't need to build another one. You guys are very creative so I know you have some ideas for a piece of equipment that would really make a nice addition to my shop.
 
Well, that is about the perfect size motor for powering a hydraulic press. Could there be damascus in your future?

As you know, a lot of motors are rated with HP that is not realistic (think of those 3HP shop vacs, 2HP routers, and 3HP skill saws). What is the current draw listed on the motor plate?

Horsepower is not a real concern here unless you have a heavy load requirement. A 6 HP motor can be very good for a grinder, buffer and such if you take the time to decide what RPM range you want to work in and fit a belt and pair of pullys to achieve that range.

Once it is running in your preferred range the motor can be a 1HP or a 6HP and you will never notice it. The belt or buff speed will be noticed however.

I already have a press so that is covered. I wanted to use it for a buffer and run it by belt to a arbor I have but thought it would yank everything out my hand at that HP and speed. guess I could give it a try. What I REALLY need is a horizontal disk sander but cant figure out how to build one with belts and would worry about a 6HP disk sander ruining handle pieces.
 
You could run the belt to a shaft supported by pillow block bearings for the buffer.

That is what the arbor is..a shaft with 2 pillow block bearings with a pulley in the middle. My concern about this is the power and speed of the motor. I have always been told that 1750 rpm is about as fast a buffer as anyone should use because it is not a matter of if but rather when a knife is going to get yanked out your hand on a buffer. I don't want it flying at me with that much power and speed. If I could slow it down some I could use it for that buffer or a horizontal disk sander, Thanks for the idea though.
 
How about a power hammer? Maybe 6 HP is a little much for the application, but you know what they say, "You can never get enough HP" :D

That will my next major project for steel making stuff .
