Is the blade running in the right direction?

A good friend of mine gave me a box of off-cuts to cab, and I recently pulled out a bluish-green and black chunk to cut. She doesn't know what it is, and I've never come across anything like it before.

 Here are a few pictures of the cab I made with it. I'd love to find out what it is!

Commonly referred to as Craftsman block grinder.  It has a following as a very good home use grinder.  Definitely not meant to be used wet.

I have an old home built 24" saw that looks something to that.
I would take one belt from the motor to the big pulley on the blade drive with the tensioning pulley
The second belt should go from the small pulley on the blade drive to the pulley on the feed drive. I run mine on the smallest pulley so I have the slowest drive speed. May need some kind of spring on the tensioning pulley. I can't see what applies pressure to the pulley.

That's my best guess, I could be wrong. If some can find a picture it will help

No Star in this material. It would be cool to do a sphere with a star in it. I will have to check into it and see if I can afford a piece big enough to sphere.

I will upload pix and the info on the motor' s plate
This is not a piece of lapidary equipment.  I am sure the wheels are for metal grinding like lawn mower blades.  The rpm's should be no more than 1725.  I, personally, would not even consider using it for my rocks.  THIS IS JMHO

Thanks for the tip.  I can get the belt size, but not sure which pulleys they need to go on to make the feed go forward.  Sorry for the picture to be upside down.

---update--- hi everyone, thank you again for all the tips. My husband has been dealing with cardiac issues, so it took longer to try them out than I had hoped, but the very first time I was successful! I used the paste flux and mapp gas torch. I really feel that the advice to use "lots" of paste flux was/is the key. My test piece was completely oxidized, except where the paste flux was. I will try again with my propane/oxy set up, since I feel more in control with the smaller flame. If it doesn't work out, no big deal, at least I can get the job done!

use a sting to measure the belt size needed.

 Machine belts wont stretch.

 Automobile belts are made to stretch in high heat conditions.
