Hi James, I switched to CBN wheels to sharpen my lathe tools a year ago, I’ll never go back. One of the cautionary statements from the manufacturer surprised me though as it read “do not sharpen high carbon steel tools as this will clog the abrasive surface”. Happily I have another low speed grinder so moved my white wheels over. Now I sharpen my hand tools on white reserving the CBN for HSS only.

Great video though, lots of great points for those that don't know a lot about sharpening yet or just getting into it. I have a bit of each, diamond, CBN and chosera.
@StumpyNubs2 жыл бұрын
I grind with CBN to fix or reshape an edge. I sharpen with fine grit diamonds (either on the Tormek or by hand). Then I strop on leather with paste. I don't believe CBN or Diamonds are really intended to give you a mirror edge on their own.

@@StumpyNubs sort of. When you consider some offer 1500-1800 grit, where a 1800grit chosera is pretty nicely polished there. Obviously going higher can get better. Those stropping films you can get to put on glass or granite are diamond based usually. And I have Cbn pastes to put on leather strop that can give a mirror edge. Both can do it. It's just a nicer edge with chosera. Maybe looking at it more from the knife world with sharpening systems only using diamond stones and getting to a mirror finish. It's doable just not as nice.

Given what you'll be using the wheel for, I would go with the 600 grit diamond wheel. For most of your sharpening needs, it will do all you need. And, if you use the honing wheel, you may not need to use your bench stones at all. But, if you're going to use a bench stone to put on a secondary (or even a tertiary) bevel, there would be no need to hone the primary bevel produced by the 600 grit wheel.

Heavy emphasis on CBN wheels are for 'hardened' metals only! The life of a CBN wheel, for production work is about 5 years. I did take an old worn out one and purposely loaded it up with soft steel, aluminum, brass and copper. After a month of sharpening my lathe scrapers on it, the colors from the softer metals was gone. Lapping fluid can be applied to the bevel of the tool you are sharpening, and it can help lift the soft metal off of your grinding wheels. If you apply it directly to the wheel, you will get sprayed, and I found out the hard way..... They do sell very hard aluminum oxide sticks to also do the same thing. Diamond wheels on a Tormek or the various clones of it, can last pretty much forever. I use the CBN wheels from D Way since the owners are personal friends. I do like the heavier steel wheels, but you have to have a grinder that will drive them, 1/2 hp isn't enough.

You mention low speed grinders and sharpeners - what RPM's are appropriate? Examples: My Vertical Sharpener turns at 160 rpm (the supply motor is 3450 rpm) and my Horizontal Sharpener (an older Woodcraft) uses a 7" stone at 420 RPM - both are water-emersion. I have 400, 600, 800 grit abrasive stones as well as an assortment of water stones and Diamond plates for manual work. I like the concept of CBN stones as they seem low maintenance - can these be used as water-bath stones?? Finally, what are your thoughts for belt grinders for sharpening?? Belt Width?? Belt Length??

I did some spindle turning many years ago (made a couple chess sets) and now I'm about to get back into wood turning, and probably some bowl turning. I need some advice on what I should get in the way of sharpening apparatus for sharpening HSS bowl gouges. I'm looking at the Tormek T800, and the SVD 186R gouge jig, but wondering if the included stone is what I need, or if I need to consider a diamond stone. I'm also unclear on whether the included stone is CBN or something else. I question whether it's smart to use the included tool to adjust the grit from 200 to 1000, because I suppose going back and forth would wear the stone prematurely. Do people typically have different stones and routinely change them? Or is initial grinding done at 200 grit, then convert the stone to 1000 grit thereafter. I'm a bit confused and don't want to spend buy something if it's not what I need. Thanks for any advice.
@StumpyNubs2 жыл бұрын
The regular stone (it is a manmade water stone, not CBN) works perfectly well. Using the stone grater to change the grit doesn't wear it much at all. It mostly burnishes the surface. You can do it as often as you like, with as much pressure as you like and it will last for many years, perhaps decades in a hobby-level shop. The diamond wheels are extremely convenient (and the coarse one is really nice for excess grinding), but for day to day use you will be very happy with the stock wheel.

How much pressure would you recommend for sharpening

If your fingertips are turning white, you're pressing too hard

Many thanks! I've been on the edge of allocating the funds for a CBN wheel for my grinder... lack of knowledge to make the decision. I'm now ready. James, are you able to suggest a good vendor? Perhaps not a large corp. - I prefer to support a quality product from a family company. Thanks.

I've watched most, if not all of your videos about tool sharpening, and have a question. When do you use the water bath thingy on the Tormek? Is it for either wheel or only the diamond wheels?
@StumpyNubs2 жыл бұрын
It is for all Tormek wheels. However, I personally only fill it when I use a regular wheel (or the Japanese water stone wheel). The diamond wheels require an anti-corrosion solution. Rather than putting the whole bottle in the machine and dirtying it all up, I just keep some in a spray bottle and keep the wheel wet as I sharpen. Works for me, but I don't think that is officially sanctioned ;)

@@StumpyNubs I saw sparks flying on what I assumed was the CBN wheels. So I assumed it was dry. Is water optional or required with CBN?

Now we just need to wait for Lonsdaleite stones. Maybe those will be better.

I think its a misunderstanding of comfort and ease, that makes people think diamond stones are the end all be all, alternative to sharpening. I went through...10? 20? who knows how many... they dont last nearly as long as synthetic's or natural stones, nor are they more powerful/faster. but I will say from experience an average sharpener will not be able to easily acquire a "Good" set of either natural or synthetic stones, its a field of study that takes some years or luck and the market is highly saturated with crappy synthetics stones and mystery natural stones. too hard, too soft, hard/soft certain spots, abrasive particles too soft. but interesting, these diamond/CBN grinding wheels, would love to try those out, maybe one day if they become affordable, don't know if I'm being silly or not but stone grinding wheels kinda scare me... I'm probably lucky enough to survive it exploding but def will lose an eye or parts of my face.
