more forge tuning; steeling the iron; rpg stuff [Mar. 28th, 2006|03:08 pm]
Doug Ayen
Well, I've been fooling with the blown burner for the new forge. It's clearly a step up or two in power, and with the right nozzle (still working on optimization of that) is clearly able to get more heat energy into the work than a venturi. The venturi-style burners are, I believe, more efficient, and should be sufficient for most work, but I think I will like having the extra power available for when I need it.

A problem that's happening more and more is that as I'm drawing propane out of the tank faster, the tanks are freezing down faster. I need either a larger tank, or to make up a manifold system for some of the existing 20 pounders.

I made up a new batch of bone charcoal, and steeled up some more iron via the blister method: pack thin wrought iron strips in bone charcoal in a sealed container (I use an iron pipe, one end welded shut, one with a removable pipe cap, with a weep hole left open to keep it from exploding) and heat for a long time. So far, my best outcomes are being left in a wood burning stove for a couple of days, so I'll need the temperature to drop a bit more so I can continue the process, having only let it soak at temperature for about 8 hours over the weekend.

Also, if any are interested in such things, I'm documenting the adventures of my character in an ongoing RPG over at http://braake.livejournal.com . Nothing serious, blacksmithing-related, or even particularly well written over there, just some character background and an in-character take on the game.

doug, I was talking to folks about the holly (we think) bushes/trees we have in our backyard that are the bane of my existance. Someone said that you might be interested in the wood if we chop them down. (They're about 6.5 feet high, with trunks about 6-8 inches in diameter, and about 7 or 8 of them altogether.)

If this *would* interest you, let me know either on IRC or LJ. (or however else you want to reach me.)
