Now were getting somewhere…

Diamonds are very aggressive especially in low grits and cause deep stria that in turn cause a rough edge.

ALL that stria needs to be removed from the bevel with a stone that is not a Diamond Plate and is in the 800 to 1K grit range.

ALL the 1K needs to be removed with a 4K grit stone, then ALL the 4k needs to be removed with an 8k stone.

You can try with your Soft Ark doing circles, 20 set at a time, be prepared you will have to do several hundred, depending on the grit of your soft ark.

Once you remove the deep stria, switch to smooth lite X laps do a few hundred more.

How large are your Ark stones?

Have your Arks been lapped flat?
