    Two suits of Armour

    I believe Iron Woodrow is correct. All of the pieces appear to be modern; possibly 19th century. They are fun decorations but not museum pieces. If you are inspired to make some armor, I recommend to study the museum pieces rather than these. These would probably not work well if worn, but obviously they were an inspiring display to enourage you to do metalwork! Best regards, Jacob
  2. BGCM will host the 30th annual Blacksmith Days this year. Dates are May 19-20. See the website: http://www.bgcmonline.org/index.php?bsd2018 The location is in Westminster, MD. There will be demonstration tents setup outside of the school shop. Advanced registration is available until May 1st.
  3. No need to be a member. I bought mine online a couple years ago, and don't remember it even asking for a membership number for a discount. I have it built and use it all the time.
  4. I need more space to do all the things I'd like to do. I could do more with the space I have if a number of projects were finished and cleaned up. I have a 1-dump truck garage, maybe 15x30.

    FLATTER HAMMER

    Really heavy set tools need to be hit really hard to transfer the effort. Really large contact areas need to bit hit really hard to do much work. If this is both, you might not be able to do much with a hand hammer. Possible alterations if it doesn't work the way you want: Get a friend with a sledge hammer, or reduce the weight (trim the struck end where it mushrooms), or dress it to a curve or less contact area.
  6. For those in the area or are willing to travel, there is an excellent event scheduled for Labor Day weekend in Dallas. http://www.ntxba.org/events.html?task=view_event&event_id=2 http://forums.armourarchive.org/phpBB3/viewtopic.php?f=1&t=147142&sid=9004c25ea0c03e9a9411066f1a97d6b0 It looks to be an awesome event. I will be making the trip from Maryland to advance my knowledge in steel repousse and armor construction. I'm looking forward to seeing some of the Western demonstrators and vendors, too. If you didn't just blow the travel budget on ABANA, check out the links and the demonstrators. They are all making top class work.
  7. A rolling mill will do well if you're just drawing out. A power hammer will also work for other forging. A flypress works well with tooling and jigs using arm power. A treadle hammer does well with freehand tooling using leg power. People will argue the details and you will find other ways to use the tools you have. I built a treadle hammer first for use with punches, chisels and sheet metal work. I'd like to get a power hammer next, but I wouldn't turn down a good deal on a flypress for being able to set up guides to make straight chisel lines easily. It sounds like you know what you want to do. Put your energy into getting or making a tool that does that well. You can waste a lot of time and resources on some other tool and it still wont be what you want.

    Business cards

    I used overnightprints because their online design tool allowed a lot more control than Vistaprints. If you have photoshop, you can go either way. There's always a sale going, so you can get "500 free cards" or whatever, and pay $10-15 in shipping. Much easier and higher quality than printing and cutting at home. It's very cheap advertizing to hand them out. I'll even punch a hole in them and use them as price tags with the information written on the back. You just have to be careful that people don't take your price tags off the table if they're not tied to the item.

    Hello from Maryland!

    Go through Dave's links above. There are a lot of groups and smiths in the area. BGCM sells good coal and has an excellent school shop, BGOP has a forge shop, and BGWM has been touring local member shops lately. I'm north of Frederick. There is a pretty active community here. Welcome!
  10. Here's the cracked hammer. The picture does not show the crack, but it starts at the face and goes back. It's 2 lbs, based on the Mastermyr viking hammers, but now it's a doorstop. I hardened it with the intent of trying a new heat treating oven soon for the tempering. I saw the crack a couple days later, before the oven was ready. I took a risk and lost.
  11. I just had a similar failure with a hammer from a torsion bar. It looked fine until hardening. I didn't temper immediately, and saw the crack. I went to anneal it to see if I could grind the crack away and the crack expanded down the length. The forging was done outside in the sun, so temperature could have been the problem. I hate seeing hours of work turn into a doorstop. I'll see about getting pictures. What is a common torsion bar alloy? I assumed 4140 or similar, but it did get quite hard. Jacob
  12. I just got my inline hammer built and have been doing some chasing in sheet metal. I've been using a block of wood under the treadle, but that would still be as bad for the linkage as stomping it to the ground. The best stop would catch the hammer head before the hammer and anvil meet. This would work well for chisels and tooling, but would have to be removed for mounted tooling including flat dies. I have seen another inline hammer design with a heavy pin that could be inserted into one of a series of through holes. I considered drilling holes through the top section of my 3" diameter hammer, but did not. A clamped on stop could be made for inline hammers, but it would not be as secure and it would tend to vibrate loose. It would also screw up my pretty new paint. I've been holding chisels by hand under the hammer, so this is a topic I've been thinking on. The heavy overhead arm with a chain is an interesting idea.

    heater and forge chimney

    What different considerations should there be for a propane heater? I have a ceiling-mounted warehouse heater and have been meaning to put the forge under it to share a 12" chimney. The main issue I was thinking of is grit buildup in the heater. It doesn't get all that cold, here.

    How to remove railings set in lead

    180 years from now, when they go to restore it again, how will the smith remove the epoxy footings? Can they be burned out or broken down chemically?
  15. A36 is structural steel. The requirements are looser than 1018 and there's often misc. recycled content. A quick check on Online Materials Information Resource - MatWeb shows it has a bit more carbon and .2% copper in the specs. Neat test. Were you swinging all out or being more reasonable?
