if anyone is secretly making pencils...

David Weaver
the height of the blank and width need to be square for an 8 sided pencil to prevent odd sized facets.

For a 6 facet pencil, the height of the blank needs to be 1.155 times greater than the width 1/(cosine 30).

You can just about see squareness. All in all, the 8 facet pencil takes about half as much time to make because you don't really need to measure anything. I'm sure someone making pencils all day every day could see the proportions that a 6 facet pencil would need to have just by eye, but I have to check them with a caliper while cleaning up the blank after sawing it out and prior to faceting.

graphite experiments next. On the fence about making a double iron V-shaped specialty plane to easily cut 6-sided blanks.
