Define "trolled". What you are reading may be non-conventional but that is
how progress is made. Many of the advances in boat design and construction
that have made their way into conventional big boat commercial shops came
from the non-conventional small boat projects of amateurs.

Speaking of non-conventional..................
I have used spay paint to color epoxy to match the pieces being glued.
I just spayed into the mix and stirred it up until I got the desired color.

This was done as a cosmetic 'fix' so the repair would not be visible and it
is sandable without changing color.

Not a marine application, by the way.

Most progress is made by folks who have both an innovative idea and the
engineering skills and material resources to test it in a rigorous way.
Trolling includes asking fatuous questions like "Can i use dust bunnies instead of

fiberglass?".

I prefer the kind that start "We were stranded on an isolated island with
nothing but a box of paper clips and a forward hold full of dust bunnies" and
end "Twenty years later and it's never given us a hint of trouble."

I've been taking a bit of flack on the FreeNet for doubting the
advisability of some of the enhancements they've been adding, which have
subsequenlty lead to security problems on our home computers. My response
to "engineers", software and otherwise, is the engineer standing up to his
waist in floodwater seriously explaining how the dam could not possibly
fail.

I don't think that's trolling. Trolling is where you post a newsgroup
article for the sole purpose of seeing how many people respond.

That was no engineer, that was a research scientist ;-P

Real engineers are the ones who say "Oh, bvgger! THe dam's bust. Now, how do
we fix that?"

I eagerly await the results of the dust bunny longevity test and have marked my 2024
calendar.

'Troll" or innovator not withstanding,
'Sevin', like just about ALL plant or garden bug/disease 'preventatives' is
TOXIC. While supposedly of no great concern when applied AS it was DESIGNED
to be used, make it airborne as a very fine particulate and THAT is another
story !!

When you mix a fine powder like Talc, etc. into epoxy {etc.}some of it
becomes airborne. We've all experienced that 'little cloud' and thought
nothing of it. Some of it definitely gets inhaled . . . that's why you can
SMELL it. That's the first time.

Secondly, when you are grinding and/or sanding down those lumps, runs, &
fillets . . . you are getting a dose of a combination of particulates . . .
the epoxy, the glass {a 'benign' substance when a solid}, and whatever the
filler material is. Even if you use a mask . . . if you can smell it . . .
guess what that THAT means !?!

There's no reason why you can't 'experiment' with ANYTHING you want . . .
anybody remember how 'Silly Putty' started? Just think FIRST about beyond
the 'immediate' activity.

Regards & Good Luck,

I understand what you're saying and I realize that nearly anything
fibrous can be used as a thickner, but I think it's safe to say that
building a boat with epoxy mixed with insecticide powder goes well
beyond the definition of "non-conventional".

Maybe the next time I need to do some fillets, I'll thicken the epoxy
with Metamucil. It's got plenty of fiber and it should help to produce
fillets that are quite "smooth" and "regular". ;-)

That would only work if the fillet were to be extruded. ;-

I'm not familiar with Metamucil but suspect it may be one of those fine
clay (kaolin) powders suspended in a flavoured water solution. If you boil
off the water all you have left is clay which, like powdered talc, which
would be less expensive to buy dry in the first place. And of course,
water mustn't be mixed with epoxy or polyester resins.

I'm not suggesting insecticide powder as a thickner for fillets. Some kind
of additive for sheathing might be interesting but expoxy itself is
supposed to be impermiable to air and water so it's probably a waste of
money. If the expoxy wears off to the point air and water get at the
wood the insecticide is gone then too.

From what I've read I would use fibre for reinforicing for structural
strength and powder to simply make the resin go further, or in the case of
silica, for added abraision resistance. Both fibre and powder would make
the resin more viscous if that's needed while curing. I've also read that
that the need to sand the cured resin influences which powder to use. I
usually collect wood "flour" for free (sandable fibre) and use that. I've
used powdered talc with epoxy for non-marine repairs around the house.
Laser toner sounds interesting except for the graphite coating. I don't
know what graphite does to resins. Carbon fibre is sought after for
combining with resins, but graphite? Imagine trying to clean up after
sanding. Ugh.
