Topic tags/keywords: waterstones flattening

For Christmas I received a set of LV chisels and was attempting to sharpen them today. I am not expert at sharpening and I’m curious what do most of you use for flattening waterstones? I’ve so far attempted a piece of sandpaper attached to a piece of fake granite countertop (sample piece) that I had to flatten. I’m was not very happy with the results. Think I skewed one of my chisels. Ooops. And never bothered to attempt sharpening the rest.

Diamond stone is what I use. Atoma 400.

L.V. has a big stone for Flattening water stones, the Lapping plate, 4” by 10” I picked one up a couple of years ago and have been extremely happy with it! Always remember that it is only for your stones, to much money to have it wrecked by flattening metal on it!

I recommend a dedicated flattening stone rather than an expensive diamond plate.

I have been using a coarse diamond stone (DMT Duo Sharp), but I am convinced it has been worn out because of it.

I have a Norton flattening stone but quit using it when I discovered it wasn’t flat. But I managed to flatten it so I use that now.

You’ll get better over time. It wouldn’t hurt to watch a good sharpener in action, to see what and how he did it. That was, for me, my Aha moment. The guy I learned from was totally freestyle with chisels and plane blades. He used a medium diamond plate, then an extra fine, then a leather strop with a yellow flex cut paste. No water stones at all. I adopted that approach, though with a Veritas roller type blade holder, for years. But recently I’ve gotten more into dovetails, which got me more into sharpening, which then got me into speed of sharpening. So now all chisels get sharpened freestyle, though the 1/8 inch LN is a challenge. All plane blades still are sharpened using the Veritas holder.

Unless the blade or chisel edge needs to be reground, I go straight to the Very Fine diamond plate, then to a Hard Black Arkansas stone, then the leather strop. Very fast. Not messy at all. Takes up very little of my workbench space. Sharpening, for me, isn’t a religious or zen experience. It’s a chore best done rapidly, so I can get back to doing woodworking.

Ive watched dozens of videos to find the right answer. I currently start with the dmt duo sharp EF unless something major is needed to be reground then switch to films out to 1 micron. I dont love the films though so im in the market for a 6000 8000 12000 stones and a DIA flat.

Dmt may be the “leader” but I wore one out after lapping the back of 2 irons. The replacement is holding up but I don’t use it much anymore.

I have an atoma 400. It’s a hair bigger than my particular stones but just big enough to work.

Few I know a guy who brings dished out oil stones back to life with water on a well-laid spot of sidewalk concrete. Dunno that i’d try this with waterstone but I cannot argue with the results as described..

I’m not an expert hand sharpener, I use a jig, but I would think your stone being out of flat is not what skewed your chisel. Rather, the way you presented it to the stone or how you applied pressure to it as you sharpened.

Even not flat stones are usually just a wavy surface with valleys a few thousands deep.

Please someone help me understand if I am wrong.

I’ve been using a Veritas jig. It is quite possible that the chisel was crooked in the jig. I did put it on a small diamond stone I had and seemed to get a much better result.

For tools I’ve inherited, I have a piece of machinist’s granite and use sandpaper with adhesive backing to start flattening, then move onto stones. I just tuned a new set of LN chisels today using a LN honing guide with Shapton glass stones flattened with a DMT Dia-Flat Lapping Plate. Flattened the backs with 4000 then 8000. Did the bevel with 400 grit on the granite, went to a Shapton 1000 to raise a burr then reset the chisel in the guide to put a micro bevel on it using the 8000. They turned out great. I went with glass stones as they don’t have to be soaked in water. Spray the surface and go. I like the DMT –especially the 4×10 size– and it does a great job for me but I would really like to try the Atoma as I think it will be less aggressive on the stones.
