Sharpening Fail

So I finally got around to sharpening some blades yesterday—several chisels and a plane iron. Everything was going fine. I have a honing guide but I just felt like doing it freestyle. Also, I usually do the Scary Sharp method with adhesive sandpaper on a slab of granite. This time though, I got out an old, two-sided water stone that I haven’t used in years. I went through several chisels and the plane iron and got hair-shaving edges on all of them. But on the last chisel, I put the bevel down on the finest stone, pushed it forward and gouged the heck out of the stone. It removed a little furrow almost an inch long. There is plenty of room on the stone, but I hate that I damaged something that required more care. In the future, I’ll either use my honing guide or just avoid orienting the chisel that way. For my purposes, the stone will work fine, especially given how rarely I use it. But I’m wondering if anyone has a method for resurfacing a water stone.

I bought a ‘flattening stone’ from last year … it does a nice job of flattening stones, and may help you resolve your situation.

I use some wet/dry sandpaper (auto body sandpaper is great) it face up on a flat surface (your granite piece….or a piece of glass…anything flat and level)...add water or oil and using a scrubbing type motion….sand the stone back to flat. You can use a fairly agressive grit until you get close to flat…then you can go to a higher grit so that you do not remove too much material. Once the stone is flat again…rinse and you are ready to go. That is the way I was taught to resurface water stones.

I’ve done this. I did what Gerry did to fix it. I’ve also done what Reggie does. It sucks to lose thickness on your stone, but lesson learned. I’ve also done the same thing on my Tormek, let part of the jig assembly drop down into the stone & grind it to a halt. I had to regrade it about 4 times with the diamond dresser (took hours) and I lost some very expensive stone in the process. We learn, brother. I’m scary sharp all the way now; I only turn on the Tormek for lathe tools or to establish a new primary on a badly damaged chisel. I also use automotive paper. I keep a little sprayer nearby with water-cut-Murphy’s oil soap. It seems to clear the grit on the coarser papers. Also keeps the heat down a bit. Good luck!

I’ve got an old 4 sided sharpening block studed w Diamond grit 200 to800 that works pretty good. You can get them from HF for I’d guess around $10

I read that you can, literally, surface/flatten it by rubbing it against a cinder block.

Cool idea Neil. I think I’ll still use my flattening stone as a last step, but that should work just fine for getting close.

Cinder block? That’s gangster.

I use an older, harder sharpening stone I found in the attic to true up my new softer stone. I’ve read somewhere when I was looking into it back then that rubbing two stones against each other makes/keeps both flat. So far it really worked well for me. I do it “a lot” though, since I prefer flat stones and some increased wear to an uneven stone that doesn’t give me good results.
