I finally broke down and ordered a CBN wheel from D-way tools on Sunday. Installed it tonight on my Delta 8" grinder. I had my Norton wheel shimmed and trued up very well. There was no way I thought a CBN wheel could be that much better. I now wish I would have purchased one a long time ago. They are that nice. Cant wait to turn something this weekend to try out all my newly sharpened tools!

I think that is everyone's thought after they buy them. I too was surprised, and I am enjoying mine also. Enjoy!

LOL standard reaction. Even some die hards have been convinced after turning on a gouge sharpened on a CBN.
The newer 'crucible metals' like V10 (Doug Thompson) or M42 (D-Way or Carter&Son) sharpen much better than on CBN as the number of microscopic carbides is much greater and the Norton wheel can only knock them out, it can not cut them. CBN can cut them and they then provide greater wear resistance so the tools stays sharp longer. At least that's my story and I'm sticking to it

I agree with Thom. I was close to replacing my Thompson bowl gouge before I got the cbn. Since I got it, the tool stays sharp much longer and a sharpening takes off much less material. The gouge will have a lot of life left.

I've ground my first beginner gouge to bits and need a new one. Time to buy a real one (Thompson or D-way from what I can tell). I was hoping i could put off buying these wheels for a while, but y'all have convinced me to do what i already knew but was avoiding...just bite the $bullet$ and get the right stuff.
ugh...my wife is gonna kill me! (i've got the new Grizzly on its way...and just replenished my sandpaper stock...and just stocked up on CA...and just replaced my worn out carbides from Captain Eddie...and need to rewire the shop...and need a proper grinding jig...and need to rob a bank...and $$$)
will i be ok to mount this on a 6" Ryobi grinder for a while? if i tell her i've gotta go buy a new grinder too, i'll be sleeping outside!

I can still remember the first time my wife was standing there when the UPS man came up with a little box that was three thousand dollars. She hit the ceiling! The walls and floor too. Luckily she is a rotten shot. After that when she asked what something cost I would tell her three or four times the price. She would get upset but when I could get a word in edgewise and would tell her what it really cost then things were OK. Of course if I had told her the real price to begin with she would have gotten just as upset and I wouldn't have had a fallback position!

Hu...some real wisdom there. I'm gonna use that approach when i break the news on why i "need" new wheels. ha!

Just think what kind of hot water we'd all be in if we bought Diamond wheels.

Brad,
You turn professionally if I remember correctly. I find the 180 grit seems to work well for finish cuts. For roughing you may want to think about an 80 grit wheel. I don't think the edge holds any longer than my old norton wheels. As a matter of fact I think the cbn sharpened tools don't hold an edge as long as my old wheels at least for my 3/4" bowl gouges that I use for roughing. The 80 grit helps the life of the edge some but still not like the norton wheels. Having said that I won't go back to the Norton wheels for the dust issues alone. The cbn edge seems to get sharper but doesn't last nearly as long IMO. When finish turning it lasts long enough to get down to the finish cut and one should sharpen before the final cut anyway.

Dale, what kind of gouges are you using? I'm interested in the metallurgy, so brand(s) not specifics unless some are powdered metal, V10, etc. If you are only using M2 HSS then you will not see that much difference and the Norton may get sharpe, but it is more of a saw tooth when looked at microscopically, and like a serrated kitchen knife will stay 'sharp' longer . Also, the sharp edge on M2 will wear down faster without the Vanadium or Cobalt in powdered metal tools. Honing helps with either metal type, but use a diamond or CBN hone.

I only wish I turned professionally! You must be thinking of someone else.

I had gotten a 180 grit CBN wheel a couple of years ago from D-Way.......I recently upgraded to an industrial rated grinder and got a new 180 grit and 80 grit Hurricane wheels from The Woodturning Store.........they are both direct bore for a 5/8" shaft, meaning no bushings.... and man are they ever smooth on this new grinder......best sharpening setup I have ever had!

There is a Brad Adams in California who is a professional turner.

Sorry wrong Brad.
Tom I have a bit of everything. A few of the original Serious tool steel but I think they have changed the metal. M2 steel from Henry Taylor (I think), M4 from oneway, 2030 from Henry Taylor (I think), v10 from Huricane and V10 from Thompson. I think that is all of them.

Roger,
What grinder did you get? I am contemplating an upgrade to my sharpening setup and the new CBN wheels I am planning could benefit from a new grinder as well I guess.
