I've done a quick search on this, and found that Glen mentions that this is possible, but not ideal due to excessive scoring and over removal of metal.
Would something like 1500 or 2000 paper be better, even if it took longer?
Or is this a pointless exercise and I should just bite the bullet and get a 1k stone?
I have plate glass / thick plexi / granite reference block / etc available to me.
Just looking for opinions and ideas
Cheers
