Several years ago I made a trade of Web work for a rock saw. It was buried in my little storage barn since then. It came without a stand but included a new motor the fellow purchased to run it.  I'm in the process of building a stand, but now I need to know what way this motor turns in order to build a mount for it. Any body know the correct way to wire this?. The motor didn't include aNY sort of pothead.

Pothead? As in some smoker? As far as wiring, it's right there on the name plate.

I guess I mean wiring TO the motor, not sure where the hot nuetrl and ground go to.

"4" (where the blue wire is) and "1" which is right below 4.  It does not matter which incoming wire goes where.  If you want to you can connect the ground to the outside case.  There may be a lug, but probably not.  Sometimes there is a lug on the base itself.

I plan on wiring a switch to the front of the stand and wiring the motor to that.

Be sure to switch the black (hot) lead.

And, FYI, it is currently set to go CCW as looking from the pulley end.  Build your mount however you want and then set the direction of rotation that you need.  Nice motor - not all motors are (easily) reversible.

Most of the time on a motor like that you swap the blue and the brown
wire to change directions. I see that's not the case here. Looks like
you don't even have a brown wire.

Here's a more detailed wiring diagram:

If you don't want to mess around building your own motor mount. Grainger has a lot of choices.

Messing around is what Im all about. I like to make stuff out of other stuff and come up with alternative solutions.  :)

The ground wire is the yellow and green wire in the 2nd photo. Usually it's located inside the enclosure like the other wires are but that will work as well.

Well, I needed to obtain a wing nut and a couple hinges. Motor mount complete.  Tighten the wing nut on the countersunk carriage bolt to tension, loosen it and lift motor to change belt speed.

I need to fab a guard yet for the motor/belts.

Nice.  But that is looking a bit fast for stone work.  Cutting maybe but the grinder I *think* you may want much, much slower.  What does Google say?

Looks like 1725, and this is  1725 motor. In the video it is running on the little pulley on the motor and the big pulley on the saw, so it should be much slower than that I would think.  Running on same size pulleys should give me 1725

OK, even for the grinding wheels?  I just noticed what looks like a ground wire on the rock sled.  I guess that guy was worried about getting fried?  I would hook this up to a GFI outlet to be safe.  My wet tile saw (DeWalt) has one built into the plug.

Not a ground wire. I'll replace that with something else. It is a cable that goes over a pulley and hooks to a weight hanging off the back. This makes the "power feed".

Ahhh, clever!

Be careful if that's a white grinding stone. They are not made to spin fast.

I guess I should ship you some geodes now!

HECK YEA YOU SHOULD!!!

I started my guard today. I
'm using an old Aluminum skid plate from an ATV.

First cuts on a Petoskey stone.

That's really, really cool , Jeff  8) 8)

I have always wanted to be able to saw up rocks  :)

That is going to look amazing when polished.  I have never seen anything like that.  Is that a mineral or a fossil stone?  If a mineral, what is it related to?

Petoskey stones are fossils

I can see already it is an art to keep the stone from moving as it is cut. After a little practice, I was able to cut this nice slice of black puddingstone.

 :o  I can see that you are gonna get fancy!   :)

Hot glue the rock to something you can clamp, or glue shims to it for the clamp to grab?

I saw in a museum that our cranberry gneiss is supposed to be semi precious, feel free to come get all you want out of the garden  ;D

It would be really cool to cut a bunch of them and use them as tiles, like on a counter top or shower stall floor.

I've cut some rocks in half and used them as pulls on cabinets.... I'll get some pics of one in my shop. I used my tile cutting saw to cut it, this thing is way more cool.... I need one of those !!!!   :D

I need to rig a coolant jug for the grinding wheels. It was gravity feed, with a port in the tray to recover. Problem is right now, Im not sure what they use in that. I think some sort of additive to water to aid in cutting, cooling, and breaking the surface tension of the water. With those wheels, I can them shape stone.This tool also has a wheel off the end to polish with I am guessing, as I have some pads and things tht go on there some how. I also have some other stuff in boxes that I am not sure what it is. I'm hoping some sort of glue for gluing rocks to sticks or something. I'll have to go out there and take some photos of the stuff to see if anyone has any ideas.  There is also a box of syringes. ??? ???

On my DeWalt tile cutting saw, there is a recirculating pump like for a waterfall.  Not big and it goes as far away as possible from the saw in the tray so the grit has a chance to settle.  It is a vane type pump like you see in aquariums so only plastic is in the water to avoid corrosion.  You could have a 5 gallon bucket on the floor with the pump suspended a bit from the bottom so the grit has a place to collect.

But a quick route might be to use a garden pump sprayer?  That would give a good, constant spray.  If you set it up with enough hose, it could sit on the floor and you could re-pump it up when needed as you cut.

JB-Weld work good on rocks.

I'd think gorilla glue might work. A lot cheaper than jb weld.

Now you can make stone drink dollies for the Mrs..  interesting tables w/ stone insets..  or hot pot plates.  I've always liked rocks.. except the ones I have to pick up out of the field. 

  I took time out to get a pic of that stone I had cut to make the drawer pull.


  i used my orbital sander to polish it, it has lost some of the sheen with time.

I like that isawlogs, Good Idea,  :) :)

 Merci! 

I was able to drill the back enough to sit the head of a 3/16 bolt and PL_ed it on , been there since.
