The Scraper's cutting edge is formed by one step on the grinder. The grinding action forms the hook.

General Guidelines
(if used)
75° 40° Alan Batty recommended 70° with the under side ground back at 40° (a relief grind). (I and many others recommend you re-grind the tool to be a negative rake scraper.)

Marty Kiminsky noted that 70-80° is generally recommended for this tool. (He did not note a personal preference though.) See also, "Woodturning" magazine, issue # 352.

Some recommend the use of a belt sander (i.e., one which is bolted to the bench, not a hand-held one). I've used that and the Tormek with the Tormek SVD-110 Tool Rest. Both work, but the Tormek grinds away less metal, so that is what I prefer.

If you chose to grind a different angle, then use the following guidance when using the Tormek SVD-110 Tool Rest:

  • When grinding angles >60°, grind in the horizontal position.
  • When grinding angles <60°, grind in the vertical position.

Notes & Comments
  • If grinding this on a high speed grinder or sander, be sure to manage the temperature so that the temper is not lost due to overheating.

  • High Carbon Steel Temperature control is critical for high carbon steel. Tempering will be lost in the steel if heated until it is blue (~550°F / 300°C). Cool by dipping as needed in water.

    High Speed Steel

    Cool by dipping as needed in water.

    Steel with Carbide Insert DO NOT cool by dipping in water. This will cause the carbide to crack due to shocks.

    It is also recommended to use a high grit wheel for sharpening carbide as lower grits can cause cracks in the edge leading to it being far more crack-ridden and brittle. (Lower grits can be used for shaping the edge -- see also, Grindstones and Other Sharpening Media - Quick Selection Guide.)
