Sharpening with sandpaper

[Displaced Canadian]

Question for those of you who sharpen with sandpaper. What grit do you use to sharpen your turning chisels?

I use 150 grit on my 6" disc grinder.

150 on disc and 400 glued to a piece of corian for honing.

Thanks, now I see what my issue is. I started with 1000 and it was taking too long to sharpen and I was wearing out a lot of sandpaper, then went to 600 and little better but not much.

I use 400 when flattening a new tool or putting a whole new fresh edge. For the secondary bevel, or for other final honing i use 1000 and 2000.
I glue some of it to glass panes, some to a marble threshold I had lying around.

I use different grits wet/dry glued to a Marble sidesplash from a sink.

I have many different sharpenig system....I am not an ace at it....my favorite is still self adhesive sandpaper on a piece of granite. I use 400 and 800 ( I can not find self adhesive 800 so I use photo adhesive spray)

High speed steel takes a aluminum oxide or silicone carbide grits -- If you are using the high durability steels like A11 or M42 - probably will be a long day with sandpaper other than for honing. Power driven disks will get you there - Worksharp or similar, but I am finding it better for honing and not good for shaping high wear resistance steels.

AAW journal has had a series of articles on sharpening and edges over the past few years and the latest I read was this spring.

I have 120 grit on the worksharp and it hones a powerdered steel skew to a edge comperable to what I get with a diamond hone -- the skew is a 2060 powered steel.

If you like polished edges,Tormek looks to be the ticket but I cannot get past the price.

Now for high carbon steel -- love scary sharp Silicone Carbide on glass --

Take a Marker and color the blade that way you can see your progress and angle untill you get the hang of it.
