New DBS-22 Setting Templates

[RichColvin]

Dan Heil developed a set of templates which make setting up the DBS-22 a lot easier when addressing the secondary grind.  And, he added the capability for a tertiary grind as well.

There are separate templates for each clearance angle.  Below are pictures of the one for 9° in use.

Primary facets


Secondary facets


Tertiary facets


These are based on these calculations:

• secondary facet angle = primary facet angle + 13°, and
• tertiary facet angle = secondary facet angle + 32°.

The great value to this approach is the ease in setting the secondary (and tertiary) facets in a very repeatable manner. Additionally, it is easier and faster to use this method than the approach outlined in the DBS-22 user manual (pg. 11).This really comes into play when resharpening a number of drills at one time.
