Ellsworth grind question

>Ken, the Ellsworth grind can be easily done on a Tormek. With their fingernail jig you leave it as it comes out of the box and just put 2" of gouge beyond the leading edge of the jig and 2" between the bar and the stone and then sharpen off what you don't want. Keep in mind that no jig available today gives you the fingernail profile; they only assist you in getting the profile by giving you a consistant starting angle and ending angle; all else is hand/eye co-ordination. The fingernail grind changes character quickly with just a small difference in angles and shapes. I like a round end but others like a pointed end. A steep side angle will give you control problems. Look at our "grinds library" at the top of this page for some examples.

>If you are using the Tormek jig for gouges, set the arrow to 4 and the angle at 65-70 degrees. I have tried a setting at 5, but like 4 better. I use this for my 1/2 bowl gouges. I don't change the amount I leave sticking out of the gouge, it is 2 1/2". For shallow gouges I usually have a setting from 0-2 and the angle between 30-45, depending on the application.

For my 5/8" bowl gouge I use the Ellsworth jig on my 100lb Delta dry grinder with a 100 grit wheel. That's the only gouge I sharpen on my dry grinder, all else on the Tormek.

>As others have said. Setting of 5 or more 2 1/2 inches are the settings that will duplicate the original Ellsworth shape. The major item is to get 65 degrees on the face. Other angels cause problems until you learn the characteristics. You can get the Ellsworth jig from him or from a catalog. Make certain the dimensions given are followe for the jug though. That will give a 65 degree angle and seeep the edges back a bit further than you can get on the Tormek. If you have an 8" wheel you'll also get a bit of hollow girnd with the jig.

>There's a nice table in the Tormak book that gives a general idea of the shapes you can get with different jig settings with different grind angles. I generally use a "3" or "5". But as someone else mentioned, the jig setting is not everything - most of the shape is defined by the operator.
