glazing of tormek stone

[DuncanvdH]

I have the tormek nearly a year, and one thing I noticed when changing the bevel on plane blades (A2 Veritas) the stone cuts very effective for a short while, but tends to glaze, requiring often use of the reactivating stone or even using the diamond cutting tool to expose a fresh stone surface.

The reactivating stone itself seems to loose its edge aswell, getting pretty smooth.

When grinding chisels, the problem does not occur, or is less dramatic.

Am I doing something wrong or is this normal?

Sincerely, Duncan

I can't answer re the A2 blades but I have noticed the same with my grading stone - it seems to have lost it's bite and the diamond tool is needed (I upgraded to the new version of this recently and its SO much easier to get a good surface)

This may relate to technique. You need to be quite aggressive with the Stone grader for 15 seconds. Secondly using the corner of the rough side will bring the surface up quickly.

Overall it needs to cut for a short while, rather than just using the flat surface.

If you need a video clip to help let me know.

Hard A2 is very tough and larger areas of metal, such as a thick plane blade, do glaze the surface quite quickly.

I experience the same thing and find it best to redress with the diamond quite frequently, but taking as little as possible with the diamond.

It is easy to set a depth of cut which is too deep and this is not necessary.

The difficulty with the stone grader or devil stone, is that you may not keep the surface of the stone parallel to the bar.
