Hi Michael,
I didn't mean to imply that the tool makes the turner. What I did mean to imply is that, with poorly sharpened tools (which is pretty much any of us new to turning and sharpening freehand, no isult intended), the learning curve is stretched out pretty far and there are many things you just can't do well.
As to "name" grinds, calling it an "Ellsworth Grind" is simply the easiest way for me to categorize it. It can also be called a modified Irish grind, a fingernail grind (with rollover), and several other things. The key part is that it is a very useful grind on a bowl gouge, and can drastically change cutting style, opening up a whole range of skills and cuts that cannot be pursued with a standard grind on the gouge. This grind in particular is just about unsustainable on a grinder, freehand, unless you are REALLY good.

Sorry if I gored your ox. I didn't quote you, nor respond by point. Must have hit the wrong "reply" button. Happens sometimes.
However, you're barking up the wrong tree. To sharpen properly you need grit, not grinding aids. To sharpen your non-fingernailed gouge versus your fingernailed gouge, versus your rougher, and even bowl gouge(s) may call for entirely different angles than others use. The best template is the one that's already on the tool. If it's doing the job for you, reproduce it, if not modify it.
I don't put the same grind on my 3/8 bowl gouge that I put on my 5/8. My 5/8 is big enough and stiff enough to hog with. The other isn't, and so is ground to a gentler purpose. The 1" is ground stubby, because if I hogged with an elongated edge, it'd take the entire Packer offensive line to hold it down even with a 4:1 mechanical advantage.
I recently changed lathes, which meant I changed toolrest styles, and the angles on my gouges had to be revised for the new angles, so I could keep my elbow where I wanted it and still get support from the different rest. I suppose I could have clung to some formula grind and sacrificed my tendons or some control, but I chose not to. The reason I was able to take that road was because I was familiar with the operation of the tools, and the basics of turning, including anchoring securely to the rest. It's a road worth travelling. Learn the cuts, then modify the tools to make them your way.The grind on the gouge can force you into angles, overhangs, and body positions you might not want to take, so I follow the order of:
1) Turner safe. Out of the throw zone.
2) Tool control. Close rest and great mechanical advantage. Geometry safe.
3) Quality control. Sever the fibers across their supported length.
4) The wood is my teacher. When it's properly cut, there's almost no pressure, and the shavings fall, not fly. If not so, I try to make it so, even if it takes a bit of a regrind.
It's my opinion, and was flagged as such.
