What do you think of your CBN wheel?
There are various threads around with people saying how much they love their CBN wheel(s), but for those researching them it can be a very time consuming process (and a simple search for "CBN" brings up zip, for some reason - and CBN+wheel brings up stacks of irrelevant stuff - anything to do with a wheel).
So I thought poll might be the way to go. Add your comments as well in a post if you wish.
Please: only votes from those who have owned or used one.

Brett, I have one for my Torment, as I was due to replace that wheel. Not only was it cheaper, but IMHO gives a better grind. Also, you don't have to "surface" the wheel or chase the wheel as it reduces in size.
I have also used CBN on a high speed grinder with Tru Gring jig. Light touch, mere seconds and you get a good sharp edge for the meanest roughing cuts thru to daintiest finishing cut.
I'll be purchasing some High speed CBN's when I replace my 50mm wheels on the dry grinder.Pat

If you google "cbn wheel sharpen" there are lots of relevant hits - I think the extra word helps google to get relevant

Thanks Bill, but I meant a search within this forum.

Hi Brett,
I love em...
That video was a while back, and it's still going strong I bought it from Carroll's wood working.

I bought a saucer wheel to suit a tool & cutter grinder but it has too much runout to be usable. So I don't know how well it actually grinds until I can get it trued up and mounted. It came from ebay but I can't find it in my history. I know the seller was from a former soviet country. Beware.

Bought a 150 mm 180 grit Woodfast wheel from Carrols. Had to replace a worn down alox wheel so it didn't hurt too much cost wise. Got to love it.

I have an 80 and 180 CBN. I find them both aggressive with removal. A VERY light touch is required.
I use the 180 on about 1/4 speed and it gives me a fantastic sharpen on the lathe chisels.
Shame one can't buy a 320 or 400. All I want to do is hone and/or bring back an edge.

As a wood carver, I can't see regular use of such an agressive method for "carving sharp" edges.
I might use one for either of two jobs
a) serious damage repair = jointing the entire edge then re-establishing the 20 degree bevel.
b) completely reshaping the edge, repurposing the entire tool (making a stop chisel from a skew).
Is there a code on those wheels which would reveal the nature of the matrix material & hardness
and the grit spacing in that? The code translation is in Leonard Lee's book.
Fine tuning lathe gouges on automotive finishing sandpapers 1K - 6K grits is good enough when
the turning will eventually be sanded. Maybe $5 for supplies! I maintain a dozen Sorby for the owner.

RV, hence the third question in the poll. There is no supposition that CBN wheels are a silver bullet.
Within the context of this thread, speculative comments from those who haven't used them are irrelevant, as are alternative methods of sharpening.
However, questions on CBN wheels are fair enough.

I have used a few and love them and by no means claim to be an expert.
Love using them and plan to set myself up with one or two.
I am thinking lower speed grinder is probably better especially if you are not 100% centered on the spindle. At the Sheparton Show I used Brendan Stemps on the new low speed grinder. Something was not running true and more pressure on the chisel had to be used to compensate. I am very happy to use a light touch and this went against the grain having to push harder.
has a little 150mm set up for his portable sharpening system and it runs sweet.

I love my CBN wheel. Its quite good for carbon steel tools as well as HSS turning chisels cos it doesn't get hot. I use it with a true grind system and a high speed grinder.

I was thinking more about my CBN wheels and how to get them to slow down. The current grinder seems to do about 2800 rpm. It's like a jet engine.
The CBNs need only the lightest touch to work. My skill is obviously low, so I thought of ways to slow the buggers down. Perhaps a drill attached to the grinder to power it....then I thought of a 5/8" shaft and a few nuts and what-not to hold them in place, use a decent ball bearing (or pillow block) on each end and make a jig to hold it around the same height as a grinder.
Make it of some ply, power it with an old variable drill and a belt/pulley, then I can use my truGrind left and right on the two CBNs almost side by side. I could mount it onto the right hand side of my lathe bed (I'm not a looong turner)
Sounds elaborate doesn't it? I just find the grinder is too fast! When I give it a "blat" to get some revs, I get such a smooth superior sharpen at 1/4 the speed....but a variable speed grinder is simply not available (here in oz, that is, like most stuff)
I love my CBNs, but they need slow, not fast for my needs... I still give them 10/10 compared to grinding wheels.
