  1. Hey guys, I'm pretty sure this is wrought iron, but I thought I should ask for your opinions too. 

    First, it came off old wagon (I think) wheels that my parents found mostly buried out behind the shop. So then I did a break test:

    The grain seems right to me, but I've never had wrought before so I'm not super sure. 

    Thanks guys!

     

  2. First off, correct me if I'm wrong, but this seemed like the best place to post this question.

    The other day I found a bunch of these rods in my basement:

    To me they feel like steel, they weigh the correct amount and my hacksaw cut it similarly to steel, but they look like they're coated in bronze or brass. My question is this: are these safe to stick in the fire? I'm concerned about there potentially being some zinc or other dangerous metals in the coating. 

  3. Well, I did what you guys suggested, and I started down at the scrap yard. Found this guy (there was like 10' of it, but I had the guy cut me 18") in about 15 minutes. I got it at 40 cents a lb, 140 lbs. This ended up way easier that I was expecting it to be (besides the digging through piles of snow at 2 degrees part).

    So would it be best to mount him with the 18" end vertical? Or would the way he's mounted now be good enough to justify the increased stability? 

  4. Thomas, you mentioned the "sweet spot" is where there is metal all the way down, this leads me to believe that the cross section directly under the work is the most important, and I can only think of one reason. Perhaps with increased depth there is more cross sectional area under the perimeter the piece, which would decrease the shear stress on the anvil steel which would decrease deformation in the anvil, allowing more on the energy from the blow to go into the work-piece (Like even though it's just elastic deformation, I feel like by the time the anvil steel releases that energy the hammer blow is already over, so it's basically useless). Does this sound sorta right, or is there another explanation? I think I'll also ask one of my professors what he thinks next week. 

  5. Here is the drawing I'm going to reference for my question:

    So I want to start making some arrowheads, and I've seen lots of people form the sockets on a hardie tool like in drawing (2). My anvil is a railroad tie plate that I found lying and collecting rust, like in drawing (1). I am thinking of making a hardie tool, made from a rail spike since they're perfectly sized for the hole in the plate. It will slide in from the bottom, and a pin (4) will hold it in place (3). I suspect this will work fine if I only do light work on this tool, what do you guys think?
