I'd love to add a dimmer to it, but considering I don't even know where or how to hook up a ground to the thing, I'm a little stumped going into wiring a switch as well. But I'm willing to learn. Latticino, good advice about the book. Do you happen to know of any resources or specific books I could take a look at to get a real novice's view of how these pieces fit together? A lot of the stuff I find online ends up being about bigger, more complex, high voltage appliances and doesn't really answer the question of how to string things together.
And JHCC, good thought about the valve. If I find that I either shouldn't or for some reason can't wire a variable controller, a valve of some kind would be great to control things with. Hopefully I won't need to, as it seems some reviews complain about the blower not being strong enough for their uses, but thankfully I have quite a small forge that I'm starting out on, so I don't think having too little will be an issue.
