CBN Grinding Wheel to Sharpen High Speed Steel Turning Tools | Woodworking 

Thanks Richard. The Wolverine jig is coming up in a few weeks. Scott

Yes, it can be tempting to buy all the cool tools out there. Thanks for watching! Scott

Thanks for the tip Mark! Yes, a slow-speed grinder would be better. The CBN wheel keeps the metal much cooler though and it cuts so fast. 3-4 seconds and I'm done. Cheers. Scott

Yeah, it's added some bling to the workshop hasn't it? Cheers. Scott

Thanks for the feedback. I'm glad to hear you found this useful! Scott 🇨🇦

No, I don't have a low-speed grinder. That would be better for sharpening, but I bought this 20 years ago and didn't think it was worth replacing with a new one. Thanks for your encouragement! Scott

This one is an 80 grit, which is very aggressive. I've since installed a second wheel that's 180 grit, which is better for touching up blades

@@HomeImprovementWoodworking ah great, thank you for the reply. I'll use it for my reference. best regards from Indonesia 🇮🇩. 🙏

Sorry, I don't know the details on how these wheels are manufactured. You would have to ask a tool company who sells these. Scott

Here's the link for the video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE--Yc7VvSV6D0.html

This specific wheel is meant for a grinder. I think you would need a wheel with a larger wheel bore for a surface grinder.

Yes, this is a 6-inch wheel. Both an 8-inch and 6-inch produce a slight hollow grind, but that's not an issue. The leading edge of the tool is what's important for sharpening. I buy my CBN wheels at Lee Valley Tools to I ensure I'm getting a good quality wheel, and the 6-inch wheel is about half the cost of an 8-inch wheel. I hope that helps. Scott

Thank you Scott and great video. 👏

I don't understand how the radius of the grinding wheel creates a correct or incorrect bevel. Can you explain? Scott

@@HomeImprovementWoodworking The angle of the bevel must be increased from optimum due to the decrease in radius of the grinding wheel. AS the radius of the wheel decreases the bevel goes further into the body of the tool leaving the leading tip unsupported by sufficient metal making the tip frail and very difficult to grind. To be fair as grinding technology has made significant changes in recent times short bevels have been tolerated due to fact that to grind beyond an 8" wheel is prohibitively expensive. In saying that, 6" wheels are not suitable. Not to put too finer point on it (pardon the pun) you are clearly self taught and I suggest you do not pose your supposition as fact.

@@HomeImprovementWoodworking No matter what size wheel you have yo can always grind it incorrectly. With a wheel too small you have no hope of getting it right.
