grind a spindle gouge to about 70 degrees

Steven Antonucci

using just the arm of the grinder jig, the way you would sharpen a roughing gouge.

If the wings are swept back, you need to remove A LOT of metal before you'll get there (to the back edge of the wing)

This method of grinding can be dangerous to person and grinding wheel, particularly if you are going for a large bevel angle. Depending on the bevel angle, the characteristics of the wheel, the applied pressure and other factors, the tool can self-feed into the grinding wheel, at which point one of the following may happen: The V-arm will kick back or the tang of the tool will bend, slamming the tool and your hand down against the V-arm, The grinding wheel will fracture, or if you are lucky, the motor will simply stall. A friend of mine hurt his hand rather badly sharpening a spindle roughing gouge this way. A better procedure is to use a platform set to achieve the desired bevel angle.

My Robo Rest makes this grind easy. I will round back the outer corners to reduce the chance of the corner catching. This may not be possible if the grind is used correctly, but I feel safer with them rounded back ever so slightly.

This is what I made

I don't know for sure if this is what everyone is calling a traditional grind. It's what I thought it is. The nose angle can be ground to different angles. I'm still learning the advantages and dissadvantages. Unfortunately my machining skills suck so the flute is kind of rough but still it works.

Using it in a push cut like you would with an Ellsworth grind I don't think it cuts any different. What I like to do with it is use it flute up in the 12 oclock position and then cut on the lower third of the wing using the wing as my bevel. This lets the wood pass the cutting edge at a very steep angle and gives a very clean cut. Also in this position you aren't putting much pressure against the bevel so when cutting really thin bowls there's very little chatter. This was a U shape flute and I'm guessing a lot of traditional bowl gouges may be parabolic flutes but I don't have a way to make one of those myself.

....John, but the original bevel was more blunt and there was no secondary bevel. I still have 2 old "bull nose" original gouges with original grind that I bought "in the beginning" 30 yrs. ago. The bevel angle is probably about 75 degrees but I haven't measured them, and haven't had them out of the storage box in many yrs. either!

Jamie it depends on whether it was ground to turn steep sided bowls. I have this one ground fairly sharp because I wanted to compare it to the Stewart Batty grind and see what is different. I will take a photo of another gouge that I used to use for bottom cutting. I now use the Hunter #4 or #5 almost exclusively for those cuts because it cuts cleaner.

I'm not a world traveler and haven't seen old turners who used that shape tool. It would be fascinating to see the cuts they make and how they like to use it.

I'll be up your way in September doing a demo for the Southern Indiana Group.

Let me know your travel schedule ....

....when you're making the final plans for that trip. We should get together!

Thanks for the responses and especially those who either sent or led me to photos.
