I am using the True-Grind Jig and trying to learn how to grind the fingernail and Ellsworth grind on my gouges. No matter how you set the jig you can get the nose radius whatever you want from a sharp point to a rounded end. My question is, when looking down on the gouge, is there a recommended nose radius for various diameter (widths) of gouges, say in relation to the tool width like radius = 1/4" of tool width. I think I am getting the point too small a radius, making it look like an arrow head rather than a bullet. I would like to know a recommended radius for a spindle as well as a bowl gouge. I have looked at a lot of photos and drawings, and there is really not much that specifically discusses the radius. Most talk is about the bevel angles.

Lift the handle, I would say. That will effectively slow the rate of change and blunt the nose. Either that, or if the jig permits, sweep before you roll.
Pointed gouges come in real handy for hollowing with the grain, but a point on a bowl gouge is a catch waiting to happen. I have a cylindrical shallow-ground gouge that I use for hogging, and it comes to an abrupt, non-skating point for plunging.

You don't say if you're using the Vari-Grind attachment as well and adjustments on that will also allow altering the grind. Here is a link to Oneway's instructional video.

Ellsworth's grind can be brought right down to the measurements. It is very much about stick out (how much gouge pokes out the front of the jig) and angles. Cruise over to the woodcraft site and download the instructions for setting up his jig. Take those measurements and apply them to your own. You may have to increase the height of the jig by putting a block of wood in the normal pocket to raise it up.
The Oneway videos were a great help. Thanks.
