Just curious if any metal pounders have tried a rocket style forge.
My only frame of reference is in the DVD's and it seems that the depth to the heat might pose a problem for me since I couldn't easily see the heat of the metal/color. It definitely appears that it gets hot enough but for small or intricate peices is it problematic without the clear visibility offered by a conventional forge?
Most of my work is done in a ferriers forge though I do occasionaly use the gas forge or a larger brick one if larger/longer pieces are being worked.

depends on your goals. i have had smaller L shape rocket stoves ive made out of aluminum self destruct by melting. that particular day i had the small rocket stove running in the driveway with the feed/air port facing a 10-15 MPH wind... couldn't have asked for better unless i piped a blower directly to the thing..lol

i would think you could bring most metals to cherry red provided you used hard woods and had a forceful air flow into the rocket.

I've never built a rocket stove or done any smithing so I really have no idea if it's possible, but I think it would be pretty easy to build a TLUD gasifier to make charcoal cleanly and efficiently (and you can cook on it so you get more uses out of it) and then use the charcoal that you get out of that in a rocket stove set up to get a really hot fire going. I know that's an extra step, but I think getting a hot enough fire to use as a forge by just using wood would be kinda hard.

I couldn't find anything exactly like what you're looking for, but here are some videos that might help you come up with something.
http://www.youtube.com/watch?v=txSD9i0R1Hs (making charcoal indoors using a rocket stove)
http://www.youtube.com/watch?v=YYDlaBFk2L8 (Charcoal making using a TLUD)
http://www.youtube.com/watch?v=4xA9nBqxPmY&list=FLA2xPFL8p_9wO8Iuwvv_pbA&index=1 (a small, portable forge). I think if you used one of the two methods in the other videos to make charcoal and then used that along with this, you could have something good. If you adapted this into "rocket forge" you could probably get away with not having to use/make very much charcoal at all).

Best of luck, this sounds really cool!

I don't know this for sure, but I have heard that the gasses from the wood weaken to the metal. That is why you use charcoal or coal to blacksmith. In charcoal the gasses have all been cooked out already.
