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(https://sharpeninghandbook.info/Images/DBS-22-Setting-Template-9deg.png)
Secondary facets(https://sharpeninghandbook.info/Images/DBS-22-Setting-Template-22deg.png)
Tertiary facets(https://sharpeninghandbook.info/Images/DBS-22-Setting-Template-54deg.png)
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.
