Edge angle
A positive rake angle is recommended by many as it reduces the chance to grab.
Be sure not to have the top of the curve to project forward from the center. To help with this, rotate in one direction only. Between rotations, lift the edge from the stone surface. This prevents working the centre more than the top edges.
Grind until you feel a burr raised along the entire edge, then hone the gouge to remove the burr.

JR DUBUY on the Tormek forum recommended using the Tormek SVD-186 Gouge Jig with these settings. It works quite well.

Alan Batty recommended 45°, and this is generally recommended by many. I certainly recognize Mr. Batty's proven experience, but I've found that the 35° realized with these Tormek settings works extremely well.
Use with the Tormek SVS-50 Multi Jig with the Open Seat.

- Tormek Sharpening Classes: Part 23 - Reshaping woodturning tools on a bench grinder (YouTube video). In this episode of the Tormek sharpening classes we explain how you can quickly and with full control, re-profile your turning tools on your bench grinder. The BGM-100 Bench Grinder Mounting Kit allows you to use the same jig settings as on your water-cooled Tormek sharpening system. It is therefore easy to do the rough shaping on the bench grinder and then continue to sharpen and maintain the edge of your Tormek machine.

Web Sites
- TurnAWoodBowl.com is a pretty good reference site for sharpening bowl gouges, especially as it regards the bevel angle you might select. (But it does have a LOT of advertisements on the site -- bit on the annoying side.)
