  1. Thanks for the kind words, everybody.



    I actually like lead. Lead is my friend.
    However, I should have added the necessary "outside voice" caveat;

    NEVER USE OR BE AROUND MELTING OR MOLTEN LEAD WITHOUT A FACE SHIELD AND RESPIRATOR!

    Or at least goggles (not safety specs), and definitely a respirator.



    Nonsense. I used to chew on lead when I was a kid, and I am.........uh............. I guess that might explain why I am as I am and not the absilute ruler of the TRI-STATE AREA!!!
  2. What Glen said.

    First: Learn to manage a blacksmith's coal fire. This is a basic skill that, when mastered, will enable you to take advantage of most of the other techniques of hot work.

    Second: How long the coal in your fire will last depends on what you are doing. If you are working with small stock, less than 3/4 inch and just drawing, punching, cutting, shaping, or upseting you will use much less coal than if you were welding billets for a pattern welded sword.

    More heat more coal.

    You cane be frugal but don't be stingy.

    My Father-in-law had a plow mule when he was young. It ate so much mule feed that he decided to wean it from the mix of corn, cane syrup, and oats. Just about the time his mule was weaned... it died. Some mules are stubborn-to-death.


  3. Better How? More definitive, yes; but not cheaper or easier! I can run the spark test and have an answer before I could even make it to town to buy acid and polishing materials.

    If you are bleeding out what is better---the sterile designed for the purpose bandage in the med kit back home; or the dirty bandana you have on site in your pocket right now!


    Thomas, there are always things that we will know, things that we will partially know, and things that we think we think we know but may not. I do not really care about the anvil in question. I thought that there were things about it that were knowable if the inquiry included objective analysis. I do not doubt that you can make an accurate identification of iron and its alloys based on a spark test, but it is an acquired skill. Simple ferrous crystalography can be taught to any trade school welding or machinist beginner such that he can make a reliable identification of any common piece of iron or steel. I got my introduction to it (and blacksmithing) as a high school kid in the Natchitoches Parish trade school in 1965. That is also where I learned the spark test.

  4. That anvil is a cast iron steel faced anvil. It is a Vulcan brand you can tell this by the round cut out on the back foot on the middle. This was a low quality make of anvil to begin with. Some one at some point really disrespected it as well The horn and face were covered with steel most of that has come off at this point. Some one also welded the horn back on you can see by the thick weld at the base of the horn. Other than the occasional light bending operation this anvil is useless for what one would consider blacksmithing. That horn is likely to come loose if it is hammered upon with any force. Its a conversation piece or a tarp weight at best. If it were a car it would be a Yogo that someone ripped the motor out of and turned into a chicken coop. Now its rusted out and full of droppings and you want to put it back on the road.

    Not a Vulcan. The waist-up part is like a Vulcan but the foot is not. This is most likely an ASO that has been repurposed. A better way than the spark test to test for cast iron vs high carbon steel is by poloshing the surface and then etching it to reveal its strucure.

  5. Liberally - is that more or less than a liter?

    No reason to use accelerates, the alcohol is better used as a disinfectant. Besides it id difficult to find 90% as most times the same size bottle at the same price now only has 70%, or only 50% alcohol.


    Glenn, I use less than a cup of alcohol. It lights wet fuel, even on a windy day, leaves no additional ash, and smells good when it burns. Walmart sells 90% in the pharmacy area. Alcohol- it's not just for lacerations any more.

  6. "In a properly managed fire the recently introduced fuel insulates the touyer and fire pot from the the burning fuel." ???????????

    How's that again? I add fuel to to the top and edges of the fire, green coal becomes coke, which burns up as it settles into the firepot, releasing radiant energy to heat the metal that I place in the burning embers. Some of that radiant energy heats other things, including the firepot. The unburnt ash and clinker settles to the bottom, but not enough to insulate the firepot. The recently added fuel serves to keep some of that radiant energy off of me, but I don't think it is helping the firepot. Claying the bottom of the pan would keep some off the heat off the twyer, and certainly keep the cast iron pan from cracking.


    John, I use a poker with a flat tip about five inches long and about two inches wide, angled at about twenty degrees. I slide it down the side of the fire pot to make an opening for the introduction of fresh coal. Move the green coal into the pot from the sides, compressing the coke and moving it into the hot spot. The fire stays concentrated and clear. Pressing the green coal in from the sided also permits you to raise or lower the hot spot, and move it around in the fire pot for focusing the heat and blast.
  7. Clean, cheap, and effective: I just dump the Kingsford charcoal into the fire pot, liberally pour 90% alcohol (both available at Walmart) over it, and light it up. I maintain a steady blast until the charcoal is alight.

  8. I don't think that a fire pot should get hotter than a black heat. A properly managed fire should have the heat focused above the touyer and fire pit. In a properly managed fire the recently introduced fuel insulates the touyer and fire pot from the the burning fuel. Using coke or charcoal requires more attention than coal because of the speed with which the fire spreads through the more pure carbon fuel. Though I am using charcoal now, I prefer coal to coke or charcoal because the smith has the most control of the fire with a good, high quality, bituminous coal.

  9. If you have no experience and no preference for a kind of hammer or a maker of hammers get the cheapest ones you can find. Modify it as you gain experience until you know what you want. Then make your own.


    I have ball peen, cross peen, straight peen, and double faced hand hammers weighing from half pound to 4 pounds in eight ounce increments. I also have some rounding hammers and sheet metal hammers. Some are slightly modified commercial hammers, some are heavily mofified commercial hammers, and some are of my own making.

    I ahve forged steel using a claw hammer, a brick hammer, a hatchet, and a rock hammer. Use what you have and see what you like.

  10. Michael, that is a great photo. It shows the smith's understanding of wrought iron's strengths and weakness and how to anticipate and use them for the project at hand. If you buy the anchor hold on to this section; it has a wealth of information on how to use wrought iron. Because of how it is made wrought iron is strong along the grain and weak across it. See how the smith reinforced and added iron to compensate for the iron's weaknesses in the small bends and stress points while maintaining a modest cross section along the long sections. It is good work by a good smith.

  11. When my days as a professional I often used a 6lb hand hammer. I never had any problem in my dominant right arm. I did get "Popyey" elbow in my left elbow. My left elbow produced a large spherical swelling that took a month to go away. I have no problem since then.


  12. In the episode where they make the pintle hinge, what's the point of thinning the part of the pintle that wraps around the upright pin? Welding the two together is sensible, but is welding necessary? Or was it simply a byproduct of forming the two to one another? I'm thinking the archeological finds are degraded and assumed welded, but I don't know that they would actually be welded. I could be wrong, and I often am, but I don't see the need to weld the pin to the spike that goes through the timber.

    Thoughts?


    The pin is welded so the pin does not twist in the socket of the spike and so that the socket is not deformed when the spike is being driven into the door frame.
