My 80 grit wheels were on the way out. Not really, but I didn't want to spend ALL night shaping. I had purchased some 80 grit diamond powder on ebay so I figured I'd give epoxying it onto the wheel a whirl.

First I cleaned the wheel really well with soap and water. Then I mounted it on the arbor. I wiped it clean with acetone. I then mixed some 330 epoxy up and added some of the diamond powder. It made a thick paste that I applied to the wheel. The paste was too thick and did not cover well. I got kind of worried so I took the flux brush that I used to apply the mixture and dipped it in acetone. I smoothed the mixture out over the wheel. Now I was worried because when I looked at the mixture I did not see any diamond above the level of the glue mixture.
Then the light bulb went off and I took the remaining diamond and sprinkled it over the wheel, and patted it. Sprinkle and pat, turn, sprinkle and pat, turn, until the diamond was gone. I then patted it even with a paper towel and left it overnight. I went out tonight and ground an agate on the new set up kind of expecting the diamond to shave off in a giant mess into the pan. Nope. It worked like a charm and shaped the agate up really well. A small amount of the diamond ended up in the pan, but nothing significant.
 Below is a picture of the wheel after I ground the agate. Looks good for now. Only time will tell how it will hold up to wear and tear, and more importantly temperature fluctuations. Fortunately where I am at temperature fluctuations mean 50 to 60 degrees. (I'm almost not kidding!) But for now, I get to save my money for more rough!
