  1. Sloss furnace is in Birmingham, and Tannehill Ironworks is nearby.
  2. That makes more sense. I was thinking that one would have to know the guessing "rules" of the others to guess correctly, but I hadn't considered guessing into the aether "fishing" for one random person accepting of the "guess" out of many hearers.
  3. I saw a bald eagle steal a fish from an osprey this afternoon. It seems that I see this behavior occur at least every couple of months or so. In fact, I don't know that I have personally witnessed a bald eagle obtain food in any other way. If I didn't have other sources, I would say that our national bird is exclusively a fish thief! How much of this type of comparison is based on the biases of the observer? I was unfamiliar with this sort of framing, but I suppose that I could talk myself into seeing "guess culture" in some people I know. It seems to me that anyone working purely in tha
  4. Some of them were repairs of broken ships. On the ship my step-granddad crossed the Atlantic in, one of the other soldiers on the ship started looking closely at the hull. The guy went to examine a few places, and then realized that HE had welded it back together after it broke in half in the Great Lakes (I don't remember which one). The welder spent the rest of the trip telling others, or just saying to himself, "my welds will hold... my welds will hold!"
  5. "You load sixteen tons, what do you get? Another day older and deeper in debt Saint Peter don't you call me 'cause I can't go I owe my soul to the company store" In the US, it is the employer's responsibility to provide PPE when it is required for the job. Any business that handles it differently is treating YOU as the consumable, and likely breaking the law! OSHA FACTSHEET PPE https://www.osha.gov/OshDoc/data_General_Facts/ppe-factsheet.pdf
  6. I hope you are not proposing that HR departments are qualified to establish skills tests that accurately determine worker capabilities. I don't know how many times I've heard "an engineer is an engineer" with respect to highly specialized positions.
  7. "One good test is worth a thousand expert opinions." -- Werner von Braun You want an expert that recognizes the (limited) value of their opinion, and that can and will recommend the right test for a given problem.
  8. You'll want to remove any forging scale and then passivate.
  9. A sheet or two of hardiboard or equivalent cement board wouldn't cost that much (~$35 for a 4'x8' sheet). You can replace just where you want the chimney to be, or a full wall. Make sure to use a wet process to cut it, as the dust is a real hazard. I haven't bought them before, but I just priced steel studs, and they aren't much more than wood. Check out the hardiboard installation guides before committing to this combo though.
  10. https://www.sciencedirect.com/science/article/abs/pii/S2352409X20303692 Found it. "Firing up the furnace: New insights on metallurgical practices in the Chalcolithic Southern Levant from a recently discovered copper-smelting workshop at Horvat Beter (Israel)." Unfortunately, this article is not open access.
  11. Thomas, I am not. How would I go about having placement on the list?
  12. Thomas, The only copper oxide reduction I've performed personally was with hydrogen gas in a TGA. I didn't smell a thing, honest! (Even had there not been an exhaust connected to the fume hood exhaust, I would not have noticed a few grams of H2O vapor in the lab.) SLAG, I am glad that you find the information to be of value. I must admit that "open access" was not particularly common during my academic years, and I hadn't thought to look for such a resource before. Stash and Frosty, You're welcome for the links. I remember while growing up that although I could find
  13. "Play sand" is crushed, at least whenever I buy it. In fact, I don't know of any local place where I could get bagged riverine sand readily. Your sources may vary. Find a bag with a tear and inspect a little bit of it. You'll be able to feel if it is sharp or not.
  14. The video only showed the nozzle, which looked modern; it wasn't obvious just what they were using. As the article has been edited in place (again!), I don't know the paper name to look up the details. I have found that whatever the name, it is (will be?) published in the Journal of Archaeological Science, which is open access! I haven't found it yet searching their articles for "copper" or "copper smelting." I did serendipitously stumble upon "Towards better reconstruction of smelting temperatures: Methodological review and the case of historical K-rich Cu-slags from the Old Copper Basin, Po
  15. Plus, I'm standing on it going up, and having to use my hands while kneeling or bent down to try to let it down slowly. I like the hydraulic idea. I've got two bottle jacks that I picked up cheap that I can probably rig to push up on a lever that would push two (different style, replacement) casters mounted on the other side of a pivot down. It would be more convenient in a self contained form factor, though. I don't know if this idea helps anyone or not, but the fact that I'm raising / lowering a jointer with it is just details. The corner posts are already in my curren
