  1. aprayinbear, I would definatly HT. What kind of resources do you have?

    Coal forge, propane forge, large vertical tank for oil?

    If you do HT it, I'd just heat up the face, about 2-3" deep, do a dull cherry red (non-magnetic), and then quench in vertically in oil. Temper immediatly to either a dark gold to a light blue. Dark gold being harder, than light blue.

    This is justmy opinion, I have never HT an anvil, but will be this summer.

    Wait for someone who really knows what they are doing to answer this. Or go look up chuch robinson anvils, and send him an e-mail on how he does it.

  2. Still making my own anvil, but have done major re-designing, figuring out what I actually need and don't need. Since I already have a normal anvil, I am going to make post anvil now. I still have to weld the face to the body, but this will be easier and will weigh between 150-200lbs. It'll be 4" square, and 32" tall. 30" mild steel body, with 2" thick face plate of 4140. I'll keep you all updated on how this goes. Sorry, if my change of course is drastic, but it makes more sense and is more in my ability range.

  3. Well, I've been doing a fair-share of reading and research for this and I'm thinking I should use 6011 for the direct contact areas of the I, and then fill the gaps on both sides with 7018. 6011 is deep penetrating, and 7018 is easy to use, fills easily, and has a higher tensile strength which betters matches the anvils face plate.

  4. Okay, well I re-read that I think i understand what you are saying.

    Make an I that is less than and inch wide and long on all sides than the anvil body. Then tack it all into place. To prevent warping, stick 1/2" bars into all the area possible under the plate where I'm not welding. Start in the middle on both sides. Then the middle of the two halves on both sides and so on. Once the direct contact areas have been welded. Move the 1/2" sticks around while filling and plugging the gap.

    Also do you I could go 1/4" or 3/8"?

    Wow, third edit now, lol. Do you think that to prevent mushrooming of the welded area done the road due to use that I should do something like this instead of just an "I"

    |--|--|--|--|--|

    I could would still be able to get 100% weld, and I would have no to barely any warpage as well. Is that a better way to go?

  5. Dodge, I'll see if they can cut it when I go there.

    Mike, I have a stick welder, but I'm going to weld it up my friend's dad who is a welder. He has a gigantic stick machine. I'll be sure to keep one handy because me and my friend really don't want to have to try HT the face after its on the anvil. :) I'll keep you all updated, but that probably won't be for another four months. I'll also take lots of pictures. Thanks for the support.

  6. This is more of a brainstorm that a problem.

    I was looking into buying a bigger shop anvil towards the end of this summer, and I did some research, and I could make one for little money compared to buying one that is the same size and model.

    This anvil is going to be a combination of a euroanvil, hofi anvil, and the german pattern.

    It will have three pritchel holes, and a 1" hardy.

    Once I have some extra money for this project (this whole project should cost around $700), I am going to buy two 12"x12"x5" A-36 plate drops from the local metal supplier. I am also going to buy a 1"x5"x36" piece of 4140.

    I will use one of the 12x12 pieces as the main part of my anvil. The other one I will cut into halves, and than rough cut to shape after that.

    The anvil will be 13-14" tall, 5" wide, and 34-36" long. Anywhere from 350-450lbs.

    I am going to HT the face plate prior to welding onto the anvil body. Do I have to worry about losing my HT when welding? The plate is 1" thick. The welding area will be preheated with a torch to 300-350 degrees. I am going to grind a 1/4" - 1/2" space between the anvil and faceplate on both sides of the body, leaving a 1" tab running down the middle of the anvil body. The first bit of welding will be to run a deep penetrating bead done both sides of the tab where there is direct contact with the face plate. After that, it will be just plugging and filling for maximum weld strengh, and obviously, to fix the gab. Will I have to worry about the plate seperating down the road? It will be heated again to 300-350 degrees after welding for stress relief.

    Is this the right way to do it, or do I not need that much welding?
    Will I have to worry about the welded area itself pushing out or the top of the anvil mushrooming?

    The heel and horn will be welded on the same way. The hardy hole will be milled out of the horn before welding it on.

    I have attached a rough picture that I just quickly drew up in paint. In the picture I have a cross section of how I want to weld it, and the blurry parts are areas that will be welded, the whole face plate will be welded, I just didn't want do the whole thing blurry. I have four sheets of paper that have detailed drawings of the whole process and anvil that I will upload once I can get them scanned.

    Also, do i want the side shelf and upsetting block on the same side or on opposing sides?

    This won't actually happen for quite a few months, but I want to learn and plan as much as possible to create the best possible anvil.

    I welcome any tips, comments, or concerns.

  7. Steve sells made that blade. And it's a pattern-welded blade as well.


    MOD correction: I did NOT make that blade, tho I have made some on steel and bronze. As I clearly stated in the gallery posting. I posted the photo because of the many statements assuming that it can not be done. Facts, and Photos speak louder than opinions.

  8. Avadon, here is a much humbler version of your's and Hofi's, but it's based off of the same design as your guys'. I made with what I had laying around, and it works great even though it's 1/4" plate. I wish I had your 2" plate. With the legs, I did the wire thing, and it wasn't quite level, the legs on the ground. So I would set a level on the anvil face, and tilt the anvil and stand until level, and then grind a little bit off of whichever foot needed it. Works great now and is perfectly flat. The anvil itself is held in place by the two U shaped pieces of metal on both sides of the anvil. Will be ordering some sika glue when I have money for it. But this is the best stand I could come up with being 15 and not really having a lot of money to dispense. :) Your's looks great.

  9. Hey all, I was looking at different peoples side draft coal forges. I noticed - seemed to have somehow never noticed this before - but some people have a side-draft where it's a "short table" & "you work straight into it" - excuse my lack of better terms. Example - Picture 1 While on the other hand people have a side-draft where it's a "long table" & you work through the side of it". Exmaple - Picture 2.

    Are there advantages to either of them, I know that in the past forges were usually built for a specific type of work, farriery, wheelwright, blades, etc...
    You can usually store more fuel on the longer table, and you support larger pieces of them as well. Why are they built that way - just felt like it, nessicty, wanted it that way, advantage??? Don't know if this is the right place or not, maybe this belongs in everything else.

  10. Lol Quenccrack, say a prayer before the sermon. :). The heat is incredible, and I can forge at a high orange color, very low yellow at 4psi in my two burner knifemaker, and weld at 6-7psi. Should be about the same for you, best of luck. After about an hour or two of running at normal forging temp, you can weld real quickly, and use little gas.

    The floor is indestructible to flux, however, I can't seem to get the flux off of the bricks now. :( & when I'm not welding it gets onto my work, so I have to grind it off when I use it next time. Make sure to use a sacrificial floor, or grind a shallow channel in the firebricks to let the flux drain out of the front or back.

  11. Hey guys, I was just skimming through the internet looking at different kinds of anvils and I came across Euroanvils. Does anyone have one or have a comment about their anvils. They seem really inexpensive, but high quality. I'm just wondering if this would be a good choice for a main shop down the road.

  12. I have never used a forgemaster, but I would highly recommend a http://www.diamondbackironworks.com forge. Worth the money, low-medium cost. Super efficient, even more if you get a idler valve. But from what I've heard about forgemasters is that they are a very good brand as well. Good Luck, hopefully someone who has used one will comment on it for you.
