One of the ladies at work call me the token American and that every company should have one.
Check our Kevin Website and Mine, there's a bunch of stuff there. I think you'll find that it's neither convenent or cheap to buy supplies locally. I've been able to airfreight supplies in cheaper than buying locally (when they where even available)
Things to definatly buy locally:
Epoxy. I'm using MGS 285 because that the only MGS available. It's expensive. When I move home, I'll switch to 385 and buy directly from the distrubutor. I'd expect the price to drop in half. IF I EXPECTED to build the entire plane here, I'd probably look at a different epoxy. Raiki Seems to have some good suggestions. The 285 has spoiled me, it very nice to work with.
Peel-Ply Check my website for the source, but it's made here in Melbourne and is cheaper than spruce. Don't know why, but it is.
Spruce I did use hoop-pine instead of spruce. It was considerably cheaper (by a factor of 10) and only a fraction heavier than spruce.
We won't COMPLETELY disregard your questions for not building a canard! With so many unpaved or partially paved strips here, I can appreciate the forethought.
good luck.
