Good going Nathan. Thanks for taking the time to post all this for us.
Quick question: I've heard it said that it's a good idea to have the blower above the gas, instead of coming in from the bottom. I too would rather do it like yours, but I understand there is a higher explosive risk factor should gas settle in the blower (when it's off) and get ignited when it powers up. Whereas if the blower's above the gas line it can't do that. The problem with that though is the heat rising from the forge after shutting everything down, and having to leave the blower on for a while to keep it from getting to hot.
What are your, or any of you other good folks, thoughts on that?
