Re: wood flour tip
Fillets are structural components, at least in a stitch-n-glue boat,
and I'd be concerned with wheat flour's tensile strength in an epoxy
matrix. Also, it contains starch, not a good thing near water.
Also, the length of the fiber is less with wheat flour than in the
wood flour made for plastics use. Length of fiber affects tensile
strength. All in all, I'd say use wheat flour, considering the cost
of the epoxy you are mixing it with versus the slight additional cost
of buying wood flour is inconsequential. You remind me of a boss I
used to have. He'd step over a dollar bill to pick up a
nickel. ;) Dan

I've used it too, seems to work fine.
Haven't done any testing, but I imagine wood flour is more fiberous, and
stronger in tension. Not that it matters for most applications we are
talking about.
Wonder how whole wheat flour would compair?

I've used flour itself as an epoxy thickener. I don't know what are the
pros and cons of using flour from the kitchen vs. wood flour, but the
kitchen stuff is cheap. I've only used it in filets, not in a gluing or

I've used a VitaMix for the same thing, works OK.
The dust from the collector on my belt sander works better though, much
finer, and doesn't need processing.
Plus, it has a certain symmetry. Sand wood off one part of the boat and put
it back on somewhere else...
