Maybe we could go to that spammer's site, and hit him with a bunch of go kart s**t he doesn't want to hear? Nice thought.

Yeah- If you want to build a kart, you're going to need a garage full of tools. Chopsaw, welder, grinder with a selection of accessories, wrenches, sockets, pliers, screwdrivers, hex keys, hammer, bending stuff, hot wrench, files, squares, pizza, beer, calculator, chain breaker, tape measure, ruler, caliper, chalk, a selection of good CD's, a well-stocked first aid kit........
You'll keed a lot of tools available to you, and the ability to use 'em doesn't hurt, either! Good Luck! -Chris
