How long do emergency flares last? About half an hour?And how many would you need to make a forge big enough to be useful? 30, 40, 50? Finally, how long would you need the forge to burn in order to make, say, a machete, a hammer or a sword? About 6-8 hours. So worst case, you need 50 flares per half hour for 8 hours. 800 flares. I think they could be better used elsewhere, and you just use a standard wood/coal forge. Do you find this valuable? |

I use a wood fuled forge for all my work and it does the job fine.

Propane fired forges are WAY easier to maintain heat.

"Propane fired forges are WAY easier to maintain heat. "Yes but i cant aford to buy one or make one. Plus i get free fire wood so im fine. Do you find this valuable? |

"that wont work you need it hoter. that just burns weeds "You need to get your terms right. When considering fuels there are two terms that matter. burning temperature and Heat. Burning temperature is the temperature of the flame at a single given point its generally measured in either degrees Fahrenheit or degrees Celsius. Heat is the total amount of energy given off. The temperature of a fuel gas depends on the fuel/oxygen ratio. In the regular atmosphere, propane burns at 1900 degrees Celsius, more than enough to melt steel (1300 degrees) and way more than is needed to forge weld (1000 degrees). Propane would work, but that puny little torch just isn't burning enough, you'd be better off just whipping up a quick gas forge. Do you find this valuable? |

Don't bother forging during the outbreak; unless you're in a base. There won't be any need for things that you can forge if you're on the move or the things you forged will be shoddy or below average. I would know.

Firstly, there isn't an "i" in oxygen.secondly cutting torches are an entirely different subject. The burning temperature of the fuel gas matters less compared to the total Btu/cuft output of the gas. This is because the oxygen from the secondary stream is reacting with the base metal to form oxides, which have a substantially lower melting temperature than the base metal does, the steam also serves as a source of pressure to blow the liquefied oxides away from the base metal. 1 out of 1 found this valuable.

Hmm i thot it was spelled oxi not oxy any way i gess i should read the cutting torch book i have and learn a few things. cersid hardly ever useing the torch and not learning about it!

thats why you can't cut aluminum with an oxy/fuel cutting torch, the oxides actually have a higher melting point than the base metal.

"I'm going to school to be a welding engineering technologist, if ya'll have any questions, don't hesitate to ask"yeah, I got one. So, I can weld a bit with an Arc Welder & an Acetylene torch. When I was taking classes for basic shop we were given the tools & scraps that we needed. Here's my question, and of course it's based on the idea that it's ZedPoc: So if I wanted to weld two pieces of metal together, what's the best way to determine quality of the metal? I'm guessing obvious signs of rust are a sign, but what else? Thickness, shine, purity, etc... Do you find this valuable? |

well if it looks like cast iron but to shiny its potsteel (the crap left over from refineing) if it dents esaly its soft (like rebar) if it doesnt (like hammers) its good hard steel. thats the basics i learned in shop class.
