Where can one find some 320 grit SiC powder for lapping?

Hello,

I am having a hard time finding some 320 grit SiC powder to use for lapping waterstones. Does anyo e one know where a small amount can be purchased at for a decent price.

Thx.
Mike

I use gotgrit.com

Shapton makes the stuff in a variety of grits. I'm not sure of the 320. Contact a shapton dealer.

Thanks for the link! I went ahead and place an order for a small amount. Their prices seem very cheap so I hope it as good as the others that charge like $32 plus $12-14 shipping! :)

Yes, they are good to deal with, have quality product, ship quickly and well packed. Years ago, they were recommended to me, by a window washer who polishes glass for a living. I watched him polish a large scratch from a 1930’s plate glass window in just a few minutes, with loose grits, an old Makita palm sander and a spray bottle of water, very interesting.

Their Cerium Oxide is very nice, though a ¼ lb is a lot of Cerium.

You don’t need much of any grit, maybe a teaspoon, of each grit to lap a hard ark and even less Cerium.
I bought a small kit, years ago, have lapped a lot of stones with the progression and still have most of it.

Loose grit is much faster than Wet & Dry, once flat at 60 or 80 grit, it goes quickly.

That is exactly why I didn't want to get a pound of it as I would never use it all. I am just going to use the 320 grit to lap a stone now and then, that is it! I have no plans of doing much more than that with it.

Thanks for the words on the company! I appreciate it!

Here in BG its a 2 $ 250 grams box it has grit from 40 to 1000 =
I have made me a bevell seter with 2 boxes of 1000 grit mixed with a cement . it is soft but it work pretty well
