How do I bevel a gouge please?
Recently I inherited a gouge (Ward brand), which has an external radius of 4mm (7mm wide). For the purposes of discusiion I will assume that the internal radius is 6mm.
What radius should the bevel on the internal be, and roughly what angle please? The gouge will not be used for lathe work.
I would assume the the angle would be 20-25 degrees, and I suppose that the radius for bevelling shuld be about 0.5 to 1mm greater than the measured radius of the internal.
My intention is to work with the abrasives that I have (nothing specific will be purchased), and I figured on wrapping a drill bit of the correct diameter in abrasive paper (W&D) to bevel it.

Unless you have an in-cannel gouge the bevel is usually on the outside of a gouge, either carving or woodturning (ouside being the part that would form a section of the outside of a circle). The bevel on a tool is dependant upon the quality of the steel in the tool and the work for which it is intended and typically ranges from around 18 to 30 degrees.
Your angle of 20 to 25 should be fine though from what I hear about hard Aussie woods probably 25 is the better end of the range. On a normal gouge I just set the tool rest the same as I would for a chisel and roll the gouge on the rest. With an incannel gouge you can put a stone in the drill press, use a die grinder or wrap abasive around a stick. You can also use a narrow grinding wheel with a crown in it. If you are going to use abrasive around a stick I would clamp the stick in a vise and move the gouge, the radius of the dowel just needs to be equal to or a bit smaller than the inside radius of the gouge. You won't use an in-cannel gouge as often as an out-cannel as the tool tends to dig in. You may want to make it into an out-cannel gouge, grind the end square and put the bevel on the outside.

I think msiemsen has nailed it pretty thoroughly for you, Brett.
Your post suggests to me you are talkng about an in-cannel gouge. These are definitely a bit trickier to form the initial bevel on than the out-cannel. I wouldn't fuss about radii as such - just work the beevel & try to keep it even corner to corner. Much depends on what you intend using it for, of course, sometimes you want to ease the corners back, but mostly these gouges are sharpened straight across, i.e. keep the cutting edge straight.

Thank you chaps. At the moment it's in-cannel (and there's some kind of ding in what passes for a bevel). So, methunks it'll become out-cannel after reading what you've both had to say.
Thanks again
Brett

Hi FF.
Gouge sharpening at 18:34 ... assumes the outside bevel exists ...
Episode #6: Sharpening – Part 2 | Logan Cabinet Shoppe
For myself, I found it easier to hold the gouge across my two hands and play 'swing and away' with the stone running away from me on a table.
And the best hint I got was looking end-on to see where the cutting edge had come down to a single line, and where there was still some bit of reflection.
Cheers,
Paul

Good stuff Paul, thank you. I'll check that out, but in the mean time I've put a slightly crude ex-cannel on it, and it cuts a groove through Spotty. It may be that I'll never use it (it just turned up along with Ron's other tools).Just making some rests for them all in the drawer atm. Rasp rests are next.
Cheers

For me at least - finally experiencing the gouge-slicing-slickly-through-some-timber feeling was addictive
Ssshnick, ssshnick, ssshnick, ... etc ... "Hey, where my piece of timber go????"
Have fun.

Ha - why should I be surpised by that? You're right though, it does feel satisfying.

Brett, you have a scribing gouge. You never know you might find a use for it.
