READ, READ, READ.... and read some more. Google your topic with iforgeiron at the end. This is actually my first post here. Recently signed up, but a LONG time lurker. I have been toying with burner building, trying to set up a midsized working forge. I've been hesitant to post and ask - simply because the more I look - the more answers I can find. That and the fact that I'm one of the stubborn people who are looking to find "my way" to build. I can't bear to ask people to answer questions on designs they have no idea what I'm doing when there ARE functional designs out there. Any odd issues or ideas I have, I bounce through the forums and topics, and try to determine the principles, and scrap ideas obviously NOT working elsewhere. So far, things have been proceeding nicely, I think. A test burn for the first time the other day seemed to go pretty well. Things need to get worked out - and using the TONS of knowledge here, I have been able to piece together what is seeming to be a functional and flexible arrangement. Keep reading, ask Google - not pester guys for the same answers that are all over. Oh, and YES I highly agree - watch out for YouTube "experts". If you like the idea, check it out in full with the appropriate questions and responses already posted here. The sheer base of experiential knowledge you can glean from these folk is remarkable. IF my ideas become fruitful, I will begin posting and sharing. If I'm completely stumped, or looking for advice on some options or techniques, I will certainly ask, but for the most part - learning the whys and wherefores before the doing is going to save you and others a whole lot of time, thought, and chatter.
