>Hi Ruth,

Have a peek at the Oneway site, they have nice videos you can watch online if you have a fast internet connection. If you want you can order for free the videos from Oneway.

The site address to see the videos is below in the link... I hope ;-)

HTH,

>Ruth, spend more time at the center of the gouge and less on the sides. That will even up the shape.

If your tool is dancing around, your wheel may not be trued up properly. Personally, I spend 5 minutes truing up each wheel PERFECTLY. Back and forth with the diamond T dresser using lighter and lighter passes using the edge of the flat rest as a guide. The result is a vibration-free grinding experience.

>Ruth, I had that problem the first time I used it. I ended up varying the amount of wheel contact time between the flutes and the tip to get the grind I wanted. If I don't want a long nose, I slow down the turn as I get to that section to take a little more off. I have to watch the profile pretty carefully or I will screw it up! Also, be sure your wheel is perfectly flat and not dished in the center!

>Ruth,

Lots of good advice above.

The "bouncing" problem is caused by an out-of-round wheel. If you have a problem truing it up leave us a post.

The pointy profile you are getting is because you are rotating the gouge through the grind at an even speed. The metal on your gouge is much thicker in the middle than on the sides, so you have to rotate it quicker on the sides and a little slower in the center. Once you achieve the profile you want, just a quick touch will resharpen the next time.

One other tip: If you have different length gouges, you can make your life a little easier by making a reference for each length. Once you get a grind angle where you want it, put a pencil mark on the arm where it slides into the base.

THANKS

>Dick Sing taught our wood turning club a little trick about the Wolverine jig. Since it is laser cut, the foot that sticks into the jig is square and difficult to spin evenly through the full arch. He suggested grinding the sharp corners of the foot into a more rounded profile to be able to smoothly rotate the jig through its full arch.

>This is a link to a handout I developed to use during my grinding instruction sessions. I explain the Wolverine set-up in there. Mainly, the nose shape is dictated by two factors:

The shape of the flute. A "V" shaped flute like a Glaser tool will give you a pointier profile, while a "U" shaped flute will be less likely to do so.

How you sweep past the nose when grinding. If you overgrind the wings, you end up with a pointier nose.

Re: Are you using the Vari-grind attachment?

>Ruth, you mentioned the Wolverine system, but you didn't mention using the Vari-grind attachment. If you are just rotating the bowl gouge in the Wolverine basket, you will get a pointy grind. The Vari-grind is necessary to grind a fingernail on a bowl gouge. Also, the jig will give you only a controllable, repeatable angle on your grind, but will not automatically give you the shape you are after. The shape comes from how much you grind off in any one particular area and is totally an eye-hand coordination thing.
