EDCO Dual grinder

[tinmanwpk]

When my son picked up my floor grinder they gave him a a dual instead of the single I had reserved. No instructions. I presume these stones stay in place via gravity/machine weight. I keep "throwing stones" every time I start the machine. They gave me 5 right hand and 1 left hand magnetic steel stone holder. Those two opposite hand holders then get everything out of balance and now my efforts are doomed. Not a happy camper.

You want the diamond tooling (dymaserts) not the carbides.

Edco has a nice video for using their machines, including how to mount the inserts (this portion starts at about 6:30):

Looks like there's also a Home Depot youtube video on floor preparation as well...
