Spindle gouge grinds

[Holmes Anderson]

When reshaping a spindle gouge, does anyone bother to grind a particular tip-to-flute angle before grinding a bevel angle? In other words, similar to grinding with the flutes against the platform when putting a 40/40 bowl gouge grind on a tool with a traditional grind.

I never did, the flutes are usually so shallow I don't think it would have much if any difference?

The Sharpening Handbook is a wonderful resource.

Thanks Jim. That page shows the rake angle but doesn't say what it should be. It seems to me that the rake angle can change over the life of the tool depending on bevel sharpening technique (more or less grind time on the tip than the sides, amount of back sweep, etc.). Not sure if it matters.

I grind the bevel angle to about 30 degrees then work that into the wings creating the fingernail grind
The way I sharpen I go gradually to a more convex bevel with each sharpening.
When it gets too convex I flatten it out.

I was a little off target with my previous response, sorry. I use a jig to grind all of my gouges so, for me, the rake angle is largely a function of the profile of the steel and the jig setting. I never try to make a cut with the wing of a spindle gouge so I don't worry about the rake angle / wing profile, I only want to have a nice round nose profile.
