Wow... I feel kinda foolish for asking this now... I didn't realize part of the face was gone, I originally saw a double table anvil (and was wondering about that). I was also wondering how I would work efficiently with it attached to the ceiling rather than the floor as my arms would tire quickly from holding everything above my head (my computer likes rotating images when I upload them... it is correct on my hard drive). Thanks for the advice

Someone on craigslist posted an anvil for sale (see pic). They say it is 146lbs and is 11" H x 4" W x 28" L. The asking price is $250... this is all I know about it. Can anyone identify the maker? Is this an anvil or an ASO? Is this a good price to pay, and if not what is?

Yes, the venturi effect is created when you reduce the diameter of a pipe a liquid (gas) is flowing through. I know I can make the burner work by reducing the pipe diameter in just about any way, but I am specifically trying to build as optimal a burner as I can. If the venturi sucks in too much air I will have a choke to fix the problem (as well as a burner flare to reduce the gas pressure at the flame). Thanks for your suggestion, I do appreciate it! ~reekanmantell

I am building a forge and came across hybridburners.com. I like the design and efficiency of those burners and have decided to play with my machining equipment and make a burner instead of buy one, however this leaves me with some questions. I have a copy of "Gas Burners for Forges, Furnaces, & Kilns", and the book has been incredibly helpful. I am milling and lathing my forge parts instead of using standard pipe fittings, and am stuck on the venturi. I read somewhere that a 20 degree angle is "optimal" for a venturi, but I want to verify this before I lathe the part. My question is this: what is the optimal angle for a venturi, and does anyone have previous experience with machining burners that they can give me advice (I see no reason to re-invent the wheel). Thanks in advance, reekanmantell

I have recently purchased a copy of "Gas Burners for Forges, Furnaces, & Kilns" and have to say it is a very informative read! I am confused with the content of the book versus the above quote, in the book the choke is always mounted to close off from the end closest to the burner flame while the above quote seems to indicate the choke performs best when closing off from the end opposite the flame. In addition the book suggests flaring the choke on the side opposite the flame to increase performance. Is there a noticeable performance gain from installing a sliding choke that closes from the side opposite the burner (as is the case with hybridburners), or does the burner perform best with a flared choke installed as in the book?
