polishing steel...

Re: first layer ()

..which for us is relatively low quality needed, I think the following are key:
* either the stone slurries and that becomes the lubricant, the stone has air space that doesn't clog, or we add a lubricant to the surface (shellac and mineral oils are not homies, so this should work - that should also keep shellac from getting stuck to a tool by unintentional friction/heat at a tip)
* nothing in the binder more abrasive than the abrasive - not sure yet about that -we'll see. Linde A is going to be very slow cutting due to the size
* a surface that has a decent feel (oil should facilitate that even if the layer must be thin) and doesn't get seriously damaged too easily - another one yet to be seen
* decent abrasive density - 30-50% should be fine. The japanese synthetic stones are sort of in a war of abrasive density, but it's a false dilemma - if a finish stone that works at all is too slow but fine enough, then more work should've been done on the prior step.

WE'll see. I'm expecting that it may take half a dozen tries with different things to get a workable stone.
