Nice! I really wanted to make one of these things awhile ago but didn't have the right materials at the time (shop-vac, wood-cutting tools etc...) And now that I do have those things, I don't have time... ah life...
I'd really like to see pictures as soon as you start building it. If it works well, maybe next time I do my next crazy project I can come over and use it? That'd be pretty cool. Hopefully you'll be able to find a good semi-local plastic dealer.
