In the ShopSharpening an Incannel Gouge Lots of people have trouble sharpening an incannel gouge. It is really fairly simple if you do it with a drill press and a mounted stone. The diameter of a stone can be changed. Just put the stone in a drill motor and spin it against a spinning grinding wheel. A smaller diameter wheel would have worked a little better on this gouge.
Here is a 1’4” incannel gouge shown with a stone mounted on a ¼” shank. The pointy looking thing is a diamond coated tapered sharpening tool. I found this one on ebay for $10.
First order of business is to put the stone in the drill press and then adjust the drill press table height so that you have the desired angle. I have this set at about 23 degrees. You can see on the stone where you have been grinding, and this allows you to remove the gouge to quench it and then return to exactly the same position you were in before. This is how you control the angle of the bevel.
Now grind the incannel bevel on the stone. The rotational torque of the stone will move the gouge to one side, so you have to counteract that force. Look at the bevel every now and then to make sure you are grinding in the center.
When the bevel is ground to suit, you can use whatever tool you have to refine the bevel. Here I am using a piece of wet or dry sandpaper to dress the bevel. I follow this with finer grits.
Finally, I polish the bevel and the outside on my felt wheel. This gouge was so small that I just used the corner of the wheel.
Here is the finished gouge. It will now shave my arm. If you are really persnickety you will want to grind the end of the gouge square before you grind the incannel bevel. I do this on larger incannel gouges, but this one is only ¼” wide, so it doesn’t much matter. This is the way I grind and sharpen incannels. You may have a better way. As usual, your mileage may vary.
