"Do not use gasoline!"

Not that I would have thought using gasoline was a good idea...but what would happen if I did? Are there some alky stove designs that would actually work with gasoline? Or white gas? I imagine it has a much higher fuel value...

I have thought about mixing up to 10% white gas in to alcohol to see if it gives any improvement to performance.

i tried whitegas in a Pepsi-G. it expoded and sprayed flaming gas oll over the concrete patio. i had backed up a long ways before it blew, cause i just didn't think that four foot high flames were any indication of a safe burn. :lol:

and; NO! i won't do it again so you guys can see pics of it. :mrgreen:

Tony, you mentioned using balsa wood for a pack frame.
I was considering the strength of balsa one day when I was thinking about DIY trekking polls. It occurred to me that balsa wrapped in carbon fiber might be able to provide a lot of strength.

Good thought and maybe even laminate some 1/6 inch thick stuff and to 1/2 inch thick and shape it to your liking. Spray or brush on some polyuretane paint and your all set. (cork grip)

Zelph, that was kind of what I had in mind.
By gluing some pieces together there's enough bulk to shape and sand it round with a nice taper.
Then wrap the carbon fiber around the balsa and apply the resin.

i recall a canoe built in Australia of balsa strips. i forget who built it and can't find the website, sorry. his concern was with impact damage to the wood and subsequent water intrusion/damage. because the wood is so soft, and epoxy/glass(or carbon), flexable to some extent, this is a very real concern.

so why not just build a hollow carbon fiber frame?
blue styrofoam insulation is impervious to epoxy, but not acetone. shape a form out of the 'foam, laminate with carbon fiber and epoxy, let it cure. once it's totally cured, start by digging out the foam at the open ends as far as you can reach in. pour in acetone to disolve the rest of the foam. flush it out with water.
