Thread: Gouge Reshape

Check out the various Tormek Videos on You Tube. I'm sure there is something there about reshaping.

Also look at videos on the new Robert Sorby system. I know that there is a great video by them on reshaping.

Jim Carroll's website is worth checking for the Sorby system and related videos.

This just looks like it was ground on a standard adjustable grinding wheel platform . Just keeping the gouge in the one position and rolling it from side to side.

The grind appears very similar to the Tormek standard profile for a bowl gouge, although thier angle is 45 degrees.
Have you used it yet, if so how did it feel? If you are happy with it, it is very easy to manually set the Tormek jig to duplicate the angle. You will find plenty of videos on the internet showing how to do this.
Carrolls Woodcraft Supplies stock the Tormek system. I found them most helpful when i needed assistance with my Tormek system.

Geoff, if you are going to use it for cleaning the bottom of bowl, grind it like a Spindle Roughing Gouge.

Hi guys,
Pat, I think it has already been ground like a SRG
It kinder looks like that grind to me
Geoff , I would try It first and see what it, s like
maybe It, s supposed to be like that...

Hello Smife, my Transition bowl gouge, has a shorter bevel, upon a closer look.270.jpg269.jpg

Geoff's chisel looks like it has a factory grind, time to experiment and find a pleasing grind.

Geoff,

You actually have the latest trend in bowl gouge profiles with that grind. Have a look at Henry Taylor Mike Mahoney Signature Bottom Feeder | Hand Tools | Craft Supplies USA which shows Mike Mahoney's signature bowl grinds. Both Mike & Glenn Lucas are very good production bowl turners & demonstrators & both have very good instructional DVD's. Glen has some YouTube clips on bowl gouge sharpening & use.

As you progress you will find that various profiles work well in certain applications and not so well in others so it pays to cover a few at least so you can play to find whch works best in a particular profile & with a particular wood.

The Kiwis use even steeper angles like 55 degrees for ancient kauri and difficult woods.

Hi everyone.
Many thanks for your input.
My gut feeling was that if I re shaped it, I would regret it. And your input confirms this to be true. If I had re ground it, I would have lost a particularly good profile.

After studying the various links and videos you provided, it appears I have something close to a Glen Lucas signature grind for fine finishing the bottom of bowls. Particularly suited to getting a smooth finish in difficult grain. The profile appears to be a modified traditional grind.

I played more with my Tormek settings to reproduce it and finally found I get an excellent reproduction with a JS setting at '-1' and P set at 65mm.
Till now I had not thought to go to a negative JS.. But there you go, just got to think outside the box.... Or if you permit me ..the bowl.
Once again many thanks. Cheers Geoff.

Way too pointy for a BOB (bottom of bowl) gouge. Most of them are in the 60 to 70 degree range. It would do well rolled over on its side with flutes at 45 degrees or so. Great on the outside. Good for the inside wall, but wouldn't go through the transition and across the bottom of any but the most shallow bowls.
