Like a lot of turners, I have always been in search of a way to get my tools sharper. I have been looking at CBN wheels for quite some time, but the cost was prohibitive.
A clumsy shop accident that resulted in a chipped friable wheel on my slow-speed grinder was the push I needed to do something. Chipped or cracked wheels are dangerous and are an accident waiting to happen.
A friend mentioned an email he had received advertising a pair of wheels for $249, so I logged onto http://www.woodturnerswonders.com/#products to check it out … didn’t take long to decide to place my order.
Wow! After I got them installed on my grinder, I sharpened up a couple of gouges and did some test cuts. I have never been able to get my tools so sharp!
The 80 grit wheel is for shaping your tools, while the 180 grit wheel puts a truly sharp edge on your tool. These wheels have a 1/4 inch radius on each side of the wheel.
These wheels are 1 1/2” inches wide, so the guards of your grinder will likely have to be removed. They are machined from one solid piece of steel and as long as they are properly used this should not cause any problems.
One of the first things I noticed was the complete lack of any vibration on the grinder. Try as I may, I was never able to get the old friable wheels completely balanced so I always had some vibration which was telegraphed to the tool. These CBN wheels are so well-balanced there is no vibration which leads to a cleaner, sharper edge.
A quick tip … on grinders with induction-type motors, give the wheels a quick spin to get them moving before you hit the power switch. The motor will come up to speed a little faster and may add to the life of the start capacitor.
