Spindle Roughing Gouge
|
|
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.

Open Seat on SVS-50
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 Live Sharpening Class - Part 9 - Sharpen a flat bevel with Tormek MB-100 on a diamond wheel (YouTube video). In this episode we learn how to use the Tormek MB-100 Multi Base to sharpen a completely flat bevel ▼, on the side of Tormek's diamond wheels DC-250, DF-250 and DE-250. For some tools, such as 🎻 luthier knives,🔪 Kiridashi knives, v-tools, chip carving knives and Japanese plane irons, a completely flat surface on the bevel is preferred over a slightly concave, which you get when you sharpen on the rounded part of the grinding wheel. For some people this is more of a personal preference.
Regardless of what might be the reason to want a flat bevel, Sèbastian and Wolfgang show how to achieve it with your Tormek wet sharpening system, They will also touch upon the differences between the different types of bevels.

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.)
