Grinding Disc

We got the grinding disc for the wheel and we bought the set of three. These things work great and I'm glad we went with the bigger size. Think the smaller ones would have been to small for some of the bigger projects we make.

Expensive, but great.

Been a fan of diamond disks for some time and have been using them on my wheel with a chamois to hold them in place on top of a bat so the bat pins don't chip my pieces.
These make the process so much easier, especially if you're using several grits.
As with all Diamond Core tools they're very nice and well put together....and expensive. Diamond Core runs sales regularly...get on the mailing list and buy them on sale.

Drip Clean Up

I love working with glazes that have a lot of movement inside the kiln. Sometimes the drips are more than I hoped for and there is some grinding necessary. These sanding disks make clean up a breeze and they are worth every penny!
