About 3 months ago I made a Deschutes cab and when I gently removed the dop, a 1/2 mm divot was created in the back. I have a hard time getting an uneven side perfectly flat to make it the bottom, using the wheels. There is always some slight doming.

I ordered an 80 grit no hole lap to do the flattening. It arrived today and took 2 1/2 months to arrive. Diamond Pacific brand but made in China. I decided to grind the back with the 80 grit wheel and then flatten with the lap. Here is the divot:

I was able to remove the divot and the back was flat, so I used the 220 hard and 280 soft. Project complete and lap not used.

I make my cabs with a higher than typical girdle so making it 1/2mm lower wasn't a problem

The pattern is relative to the whole story. I don't rock hound, go to rock shops or shows. I buy all slabs from pictures on the web and spend a lot of time looking for patterns. I enjoy that a lot more than grinding. This is the only picture and it is cropped. I knew there had to be something there to work with. I paid $20 for the slab and for that amount I expect two get more than one cab.

When it arrived I laid out two cabs with this one as the primary. The secondary fractured on the saw. I ground this on,e sanded and polished it and everything is fine until I took it off the dop. I have made thousands of cabs and the divot has happened 3 times and two were from the same piece of pet wood. A cab isn't finished until it is put in a storage box and I've found fractured cabs in a box.

It's like running a 20 mile marathon, then tripping and breaking your ankle with 300 yards to go! You definitely have an eye for some beautiful pieces!
