- Tim Cook shows a quick demonstration on how to shape a grind rock for sharpening bandsaw blade to be used on a portable sawmill or resaw.
He draws this out on a board and then demonstrates the technique on a sharpener.

Very useful technical discussion of what part of the grind is important!
I logged in just to say this is by far the most informative video Ive watched answering multiple questions Ive had-thank you
Thanks for the video. I have watched the 3 videos on the sharpener and the setter and I am considering purchasing this year. Having heard you talk about shaping the grind rock I was hoping there would be a video about how to do it.
Hi Len, I just want to say you will not be sorry, I had a woodmizer sharpener and single setter, and upgraded to the cooks cat claw sharpener and dual tooth cut my filing time down to almost nothing. I reccomend cooks sharpeners over woodmizer any day.
I have a summary according to this video, Some use PA (pink aluminum oxide) grinding wheel, some use white, this type is SG grinding wheel, better than other aluminum oxide grinding wheels, CBN wheel also can be for this usage. As for dressing stick, grit should be rougher than the grinding wheel. Some even use 24#
Thanked fo your experience and good job
Tim, I have found a diamond grit dresser to be more efficient to shape the wheels (rocks).
Are the CBN wheels worth it? How long would this wheel last typically?
👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻
When did grindstones start being called rocks?
When rocks were turned into grinding stones way, way, way back..
Good
What do you use to shape the grinding stone?

Been using pink stones. Are the blue better?
I've been trying to make the base of the gullet flat to confuse where a micro crack wants to start because when you have the 1 low point, the micro crack, that quickly turns into bigger crack always starts there. Maybe I'm on crack, but it seems to extend blade life??
I've had to grind the cam down & build a portion up to make that happen. My theory needs lab testing/results !?!?
The blue rock is a little bit of a softer rock and provides a little slower but a finer finish grind.
Typically cracks start in the gullet as a result of heat produced by grinding so keep that in mind as you are sharpening your blades. If you feel a necessity to grind the gullets do so very lightly.
