[Regia-NA] Circles and dots

[list-regia-na@lig.net]

Dunno what the handle of your screwdriver is like, but maybe you could drill
a hole through it and then insert a dowel perpendicular to the handle to
give you more turning leverage?

My husband did some work with ring-dot drills while making an antler comb.
His notes are on the following web page at the bottom of the page.

The basic conclusion was that the ring-dot pattern is made from the
beginning of a drill hole--
you just don't drill as far.  Modern spade bits will produce the same
pattern.
