This is a simple Ellsworth style grinding jig I made to fit a Hurricane 5/8" bowl gouge. Just add a threaded rod/cut bolt and a thumb screw. I have a bunch of them. I was so glad to print since that allows you to make a round hole with a flat top that keeps the gouge from rotating. If you make this by hand with wood or aluminum, the gouge can rotate in the hole, which makes you grind more metal each time if the angle isn't perfectly matched each time you go to sharpen. this jig has helped me stretch my gouges out a lot longer!

I had a problem where my print service made it too small when scaling it into their printer. so I just redrew it with a larger hole. Ill post that as a separate item.
Unfortunately I had this printed by a free local service so I had no control over it. It was printed with a MakerBot, but thats all I know. I had to make a second version enlarging the hole. Ill post that as a separate item. It printed infilled but I would have preferred solid. I drilled a hole and filled with some spare epoxy actually so I could thread it.
tap both small holes with a 1/4-20 tap. cut the head off a long 1/4-20 bolt or thread rod and cut to length for your gridning jig. Mine is about 4.5 inches total. the long rod goes in the 45 degree face.
the other small hole you tap for 1/4-20 is perpendicular to the main whole. Put a 1/4-20 thumb screw in that hole to tighten your gouge up against the flat surface.
This keeps the gouge from rotating when you re-insert it.
