I inherited most of the tools I own from my grandfather and my uncle, and with their tools I got a number of oilstones ranging from fairly coarse all the way up through an extremely hard and fine translucent Arkansas stone. (BTW - This may be the only time I will ever beat Todd's price on something, since free beats $3. Even the fancy boxes were free - I made them out of pallet wood. But I digress.) The coarser stones were badly cupped, and while they were fine for chisels (you just needed to control the angle of attack to keep the blade in a locally flat region), they were starting to be a real problem for plane irons. I tried a bunch of things (short of actually spending money), but what finally worked was just rubbing two of the stones together until they were both flat. This does take a while and you do have to be careful not to turn a cupped stone into a convex stone, but if you keep checking your progress with a straightedge, you can't go wrong. I didn't verify the flatness with a laser beam or anything, but they passed my straightedge test and they seem to work fine for plane irons now. These stones and an old hand grinder with an extremely coarse 5" wheel for rough shaping (also free - scavenged from a friend's grandfather's basement) are all I use.

Greetings all, With the recent discussion on flattening stones, what about oilstones. I use ss and waterstones, but got a couple of oilstones thrown in with a recent garage sale purchase (old workmutt, I never had one before) I thought oilstones were suppose to remain fairly flat, but at least one of these needs some work. It looks like they're in the medium grit range beneath the gunk. Is there a best method for flattening them? Thanks, Janet Fisher yes, still here, now on the west coast of Fla. |

I've never managed to flatten my Aloxite fine stone with coated abrasives. Loose grit on glass works however. My experience with 2) is that this works for all natural stones that I've met. An argument for using natural versus ceramic-based stones? Au revoir, Jeff Jeff Gorman, West Yorkshire, UK Jeff@m... http://www.millard.demon.co.uk/Index.htm |

This seems to be true for all typ es of stone 2) All stones are cut away quite easily by Silicon Carbide or Aluminium Oxide ab rasives. To flatten a stone, abrasive on a flat surface (typically glass is a good accuracy/cost compromise) works nicely. I use 120 grit to get "close" and 220 grit to finish.

Works well except on very long stones where it is hard to get a perfectly flat surface across the whole length because the stone being flattened overlaps the diamond stone. I get them close enough for both chisels and planes. If I was really worried about flattening the larger (10 inches long or so) stones I would get a bigger diamond stone, mine is about 3x8. Thomas F.
