Hexagonal dowels
Marcel Goulard
cross section could be found?
ie. All sides the same length and the same interior angles (120 degrees per
internal angle)?
Ideally precise enough to bundle together without gaps.

Let me know what you come up with. Us puzzle maker are always looking for
hexagonal stock and techniques for making it.

Having never tried to make a hexagonal dowel myself, my first guess would
be to use something like a milling machine with a dividing head.
Dr. Rev. Chuck, M.D., P.A.
Flyrod makers use a block plane and a steel mold to shave strips of bamboo
into perfect 60 degree triangles for assembly into hexagons. Accuracy is
at least as good as milling, if invisible glue lines are proof. Redesign
the mold to cut hexagons instead of triangles.

In Coffin's 1985 book he describes an attempt to use a vertical mill and
states that the results were unsatisfactory. The problem is the wood
flexes against the face cutter. He ended up having the puzzle made in
plastic and only a few prototypes were ever made in wood.
Mixed results have been achieved using square stock on a table saw with an
angled jig, but not working from a center of rotation makes it quite
difficult to get excellent results.
You might properly support the stock if it were first turned into round
dowel and then cut into hexagonals using the same center of rotation.
Pretty expensive method but I think it might work. For this, a milling
attachment on a lathe would be preferred over a vertical mill.

this method is that of stresses in the wood causing it to warp, but that
would be the case with any cutting method. Several methods come to mind, non
of which are particularly simple and a lot would depend on the length of
dowels to be made.

this message while fiddling with a pencil - a hexagonal pencil! Not much
good as a dowel but it might be worth trying to work out how pencil
manufacturers achieve it.

are made a dozen or so to a blank, and the grooves for the lead are machined on
one side and the top half is machined with three sides. With as large a scale
as they are made on, and the small size of the blanks, they can afford custom
tooling. There was an article in Fine Woodworking on them some years back.
