Tormek?Ellsworth grind?

[Atwerz]

Will the Tormek sharpen the Ellsworth grind? I dont have the Ellsworth tool yet but do have the Tormek. Thanks

It should, and there should be some info in your book about it.

Jeff Farris has stated "Use a 2 inch extension (protrusion) at a number 5 index to obtain an Ellsworth Grind on a bowl gouge."

Another user states: "The Tormek does a very good job getting that frind. 2" and a tad above the #5 will do it. It is not exactly the "Ellsworth" typr grind but is almost as good as Divid Ellsworth's jig. The Tormak does not continue the 65 degree bevel all the way to the end of the wings. But if you use the "Ellsworth" tool as he teaches it you do not use that part of the wing anyway. So for the majority of your cutting using David's technique the Tomek is bette than any other system (except David of course)..:>)"

Lastly, another user states: "I have an Ellsworth jig that I've rigged up to work on a Wolverine
jig (need a block to get the geometry correct). I've also rigged up
the Ellsworth jig to work on a Tormek and have been able to get the
correct grind. However, I haven't been able to exactly reproduce
the geometry of the Elsworth jig with the Tormek gouge jig in such
as way as to make it easily repeatable. I can easily get a very
similar grind, but not an exact reproduction. In the long run it
really doesn't matter. The Ellsworth jig is cheap and it's fairly
easy to rig up to a Tormek so I use my Tormek jig to give me a side
grind that I like and let the Ellsworth jig produce an Ellsworth
grind on an Ellsworth gouge."

Hope this helps.

i find that variances on the the ellsworth grind don't matter as much as consistency of the grind you get. If you can get a consistent fingernail grind and it works for you the ellsworth techniques will work for you. They may not be his exact technique but in the end you will never reproduce his exact technique it will be the technique you are comfortable with.

Tormek and Ellsworth Grind

Use a projection of 21/2 and about one mark beyond the last one on the jig. As stated above it will not give the exact Ellsworth grind but it is so close it won't matter. I had an Ellsworth gouge from him and set the Tormek as above. Using the Ellsworth jig for sharpening I find the wings are a bit longer than on the Tormek. Advantages of the Tormek is that it does not take as much metal as off as some of the other methods..

I get an essentially perfect replication of the Ellsworth grind using my TORMEK by setting the protrusion at 2 13/16" and the jig setting at 4.5. I set the grind angle to 65 degrees. Just as with the Ellsworth jig, the results that you get are highly dependent upon how you grind the wings. With these settings, I am able to maintain the large edge angle along the entire length of the wings. These settings allow me to have wings that go back a bit less than 3/4 inch from the tip. The one shortcoming is that the jig hits the bar on both sides so that there is a tiny bit at the very back edge that I can't grind on the TORMEK using this method. It's hardly enough to even notice (about 2 mm), but I have decided to build a fixture to hold the Ellsworth jig for the TORMEK. It's not any bigger deal than building a fixture for any other grinder. The only requirements are that the pivot point for the Ellsworth jig needs to be 4" below the center of the grinding stone axis and 7" in front of the stone. With a protrusion of 2", this setting will actually result in a bevel angle of 55 degrees, but with slight adjustment of the nominal 7" dimension to about 7 1/4", the bevel angle will be 60 degrees.

I have an Ellsworth gouge and shapen it on a Tormek using the same settings as CTutor, and have been pleased with the results.

Here is an article I wrote some time ago about doing this using the Oneway wolverine.
