« Part 8: More Bowl Work and Finally Some Work on Lidded Boxes Part 9 of Lidded Boxes series Part 10: Ambrosia Maple and Brazilian Cherry Bowls »

I wanted more of a fingernail grind on my 3/8 inch bowl gouge. It is a Robert Sorby tool that I like but I had messed up on sharpening it. After taking a Woodcraft sharpening course, I felt I could better use my wet grinder to shape this gouge better. I also watched Sam Angelo, the Wyoming Wood Turner, explain how he shapes the wings on his bowl gouge. I found his presentation to be very instructive and helpful for me.

I use Tormek jigs with my Grizzly 10” wet grinder. I bought this Grizzly instead of the T-7 Tormek in order to discover if wet grinding was really the method I wanted for sharpening hand and turning chisels. I did not want to expend that amount of money if I quickly learned that this method was not helpful for me.

I have since decided to use Shapton glass stones for hand chisel sharpening. I use a method similar to Rob Cosman’s method; however, I do use Veritas honing guides to set my bevels or angles.

After attending the sharpening course at my local Woodcraft store where I saw demonstrations using the Tormek wet grinding process. I have seen videos before, but this “hands-on” demonstration gave me the knowledge and confidence of how to setup the machine and jigs better.

This was my setup to begin reshaping the wings on my Robert Sorby bowl gouge.

I continued grinding until I got the the wings as shown below.

From this state I worked one wing before grinding the opposite as the Wyoming Woodturner instructed with the with the SVD186 jig. Of course the bowl gouge is set first in this jig using the Tormek TTS100 gouge jig. It would be impossible to correctly sharpen a bowl gouge with the TTS100 jig. I worked one side until the flat areas disappeared. I was careful not to spend any time grinding the nose or point of the gouge. I saved that for last.

Tomorrow I will grind my Wood River 1/2” bowl gouge in the similar manner.
