Sorby Proedge/Ellsworth grind?

I recently got a Sorby Protege Sharpener. I am having a difficult time getting a satisfactory Ellsworth long grind with it. Has anyone else had this problem and did they figure it out?
 
You need the long grind jig. It doesn't come with the sharpener: other wise the jig won't swing far enough to grind the sides.
 
I have the long grind but am wondering about the angle adjustment setting. And how far the gouge should project out of the guide.

John, I have the ProEdge, but do not use it for gouges. They have a guide plate for the protrusion and I have it (though never used). I use the Hannes Vector Jig for all my gouges. I can sharpen down to 1/2” flute remaining. The Proedge template requires about 4 1/2” protrusion for 35 degrees and about 1 3/4” degrees for 50 degrees. So using the ProEdge for gouge sharpening you will be giving up a lot of tool life. I do really like the ProEdge for all my skew, parting tools, scrapers.

William, Thanks for the Protrusion numbers. I do like the Proedge for sharpening my scrapers and skew. i've been sharpening my gouges on a Woodcraft Mark ll belt sharpener. It's a machine that Woodcraft manufactured in the 1970's until the mid 80's. I have been using a modified Wolverine setup with an Ellsworth guide. I thought that the Proedge might be more efficient but I guess the jury is still out on that.

The proedge is a bit easier to control the grinding. I use it for all my gouges. My cbn set up rarely gets used.
 
John- do you change the angle settings on the jig holding the gouge for various gouges and grinds? And the length they protrude from the jig? I'm trying to get as much information as I can. Thanks.
 
The long jig has three holes and they each correspond to a 5* difference in the angle that will be ground on the tool. If you use the 45 setting on the guide plate with the jig you will get 45, 50 or 55 depending on which hole you use. Hope that helps
