Alright, I'm a moron.

I bought a Coote grinder and a Grizzly motor, both with 5/8" shafts, thinking somehow I'd just stick the motor on the grinder. I guess I actually need to attach a pulley to each shaft and run a belt between the two pulleys to make the thing work, right?

I also underestimated the amount of work necessary to wire the dang thing. There are six yellow wires with exposed ends in a box on the motor. The switch I bought for it only has four prongs. I have no idea which wires go on which prongs, or even how to connect the wires to the prongs. I'm assuming the extra two wires are for connecting to the cord that I still need to buy... I'm thinking a call to an electrician is in order at this point. Does anyone have any experience with this? Should I call an electrician or is this easier than it looks?

I will take a shot at your question here.

There should be a wiring diagram for your motor somewhere, possibly on the back side of the cover for the box that contains the wires on the motor.

On the motor name plate I assume under voltage it says possibly 120/240 if it is a single phase motor.

The way you hookup the six wires you have will decide what voltage the motor needs to run. The diagram will tell you. The wires should be numbered to match the diagram.

The switching will only involve breaking the hot side of a 120 volt hookup. Or one of the hots on a 220 volt hookup with a switch that is rated for the duty in has to perform.

If this is all confusing you should probably seek out a friend who has some experience with wiring or hire an electrician to do it. This may save you money in the long run as it is possible to "toast" the motor if it is wired wrong.

That feeling you have right now is a good thing when you think about it. Its fear.
Fear of the unknown. Just follow the insturctions to the letter on the diagram and it should work or send the motor back and buy one prewired.
It always just seems to me that folks try to buy what is less expensive and end up inthe soup. I know I do it to . But there is a good education being built as you go.
Motors are one of the most complicated things to wrie if you dont know the code. You think they manufactures would get there act together and make it easy for the non electrician to wire them. Well enough whinning.
Good luck.

e_utopia,

It's a 2 HP Grizzly motor; I want to wire it for 110 volts. I think all I need to do is buy a few pulleys and belts to attach to the shafts of the motor and the grinder. Somehow I thought they'd just plug directly together.

I guess this way I can get different speeds, though, so that will be useful.

Norseman,

There's some sort of diagram on a plate attached to the motor, but I think it's in Greek or something

so right now I'm thinking an electrician would be best.

Darrel,

Actually, I think it's fear of electrocution.

Thanks for the help, guys.

Well, if you want to chage speeds, then go with pulleys. If you want them to "just plug directly together," then you want a coupler. It is a hollow shaft who's inside diameter is the same as the outside diameter of the shafts, with set screws to affix it to the shafts.

As for wiring, if you don't understand that diagram, call an electrician (our race car just lost a $1000 fuel-injection computer 'cause people re-wired it without understanding what was going on), and you'll be happier in the long run.

I have read of folks using a section of garden hose slipped over each shaft(one at motor, one at grinder) and secured with samll hose clamps to make a power transmitting coupling. Nice thing is that it is shock absorbing and semi flexible(call it a harmonic dampner). sounds OK to me.
