  1. Look at Holland anvils, and Jymm Hoffman anvils.  Both are members of the site and are extremely helpful. Tell them IForgeIron sent you.  Jymm also sells hammers.  

    An anvil in the 100 to 150 pound range will do a lifetime of work.  If you find an anvil of 200 pounds at a good price, consider it but it is not necessary.  Heavier anvils are generally needed for some types of blacksmithing or industrial blacksmithing, due to the nature of that work.

    There is an entire section of the site devoted to anvils.  For used anvils read  TPAAAT - Applied Anvil Acquisition Technique and the section on Improvised anvils

    Is anyone going to be selling IFI tee shirts this year?

    IForgeIron shirts are only available through the IForgeIron web site and IFI store.   All the shirts are printed in house and help support the site.

    All the IFI shirts and designs are copyrighted.  If by chance you see anyone selling the IFI shirts, please get photos and the name of the seller if possible.


    IFI has many shirt designs, and is adding new designs.  I will post information in the store shortly. 

  3. Just use a hammer to drive the anvil into the ground so the face of the anvil is the correct height for you. Start with the anvil face height about the same height as the break of your wrist.  To fine tune the anvil height even more, put a piece of wood on the top of the anvil and hit it 3 times with a hammer.  If the crescent is at 12 o'clock the anvil is too low.  If the crescent is at 6 o'clock the anvil is too high. If the crescent is at 6 or 9 o'clock, you need to adjust your grip on the hammer.

    Use a grinder and smooth up the top of the anvil.  Make a couple of U shaped brackets and drive them into the stump to hold the anvil in place.

    You will find that if you raise the forge up to a convenient working height so you can stand to work, you will not have to be getting up and down all the time.


    Meeting Info:

    When: Saturday, October 16th, 2021

    Where: Guilford Art Center
    411 Church Lane, Guilford, CT

    What: Meeting Business, Multiple Demos, Merch Delivery

    What you need to know:
    While we are optimistic we are still being cautious. As this meeting is indoors we would like to request everyone please wear their masks while attending the meeting for your safety as well as everyone else's. We are excited to be back in-person, but we are still thinking about everyone's safety.

  5. Do not have a smaller pipe? 

    If you tell us you can not do something, you are right, you have already decided that you can not do it. 

    Instead, figure out a way to use what you have to make what you need.  Your a blacksmith, heat up the end of the pipe you do have and swage it down to a smaller diameter.  Calculate the internal area and make the new opening round, square, rectangular, etc with the internal area you want.

  6. Try one change at a time and see what happens.   If you like it, keep it, if not, change it to something you like better.

    First add more fuel to the existing set up.  If the fuel burns down below the top of the sides, add more fuel.  If you need to raise the sides, add more bricks.  Forge with the new set up for a while and see how it works.  Then change one item and forge with that for a while and see how it works.  And so on.

    You seen to be trying to overcompliment simple.   No reason to try to cut and shape bricks, just use whole bricks.  No reason to angle the air pipe down because it will create a chimney when the air starts flowing back up the pipe. 

    What we are trying to accomplish is to create a fireball larger than a ping pong ball with maybe 3-4 pieces of charcoal burning blazing hot.  That can only heat the end of something and only heat a distance the size of the ping pong ball.   Create a fire large enough to heat the size metal you are using and for a length that you can forge in one heat, maybe 4-6 inches.   If the firebox needs to be deeper, simply stand the bricks on their ends.  If it needs to be longer, add another brick.

    Slow down. Add more fuel and see what happens when you apply a little gentle air.  Get back to us with the results.

  7. What size if the air pipe going into through the brick into the forge?  

    Suggestions are to add more charcoal, enough to be almost level with the top of the sides of the forge.  Fuel does not make the fire hot, air makes the fire hot.  When you have more fuel you can then control the amount and shape of the fire with the air.  Gentle air is best.  This can be done with your current set up.

    After more fuel, raise the air pipe say 2 inches above the floor of the forge.  Going to the next smaller pipe size will help as it will create more of a forward air blast, and move the fire from the end of the pipe.  

    All this should create a fire ball that would fill the gap between the side wall bricks.  The sweet spot of the fire should then be 3/4 up the side walls. The fire should be just a bunch of glowing embers, with no aggressive burning.  Fire does not make the metal hot, the heat transferred from the glowing embers make the metal hot.  

    You got a good start, you just need more fire.

  8. Offer the product or service to your customer knowing it is the best you can do.  With a years practice and experience you will be able to offer a product that is again the best you can do, and the second one should be an improved version.  

    Like S hooks, the first one will always be rough, number 10 should be better, and number 25 should be better still.   Can YOU tell the difference between the S hooks that were made free hand on the anvil and those made using a jig?  Will one hold more weight than another?  Can you tell which one you modified from a S hook into a J or C hook to please the customer or match their needs?

    The price difference should reflect the increased cost of materials, and your improved skill and expertise.

  9. When bending 1" square tubing into a 7' diameter half-circle, remember that metal likes to spring back and not hold exactly to the curve of the jig. You can bend against the jig and then heat the metal to relax it a bit and avoid some of the spring back.  Or make the jig smaller than the intended bend so it accounts for the spring back.

    That 7' diameter half circle will take some 11 feet of material, but you will need extra material to make the circle beyond half to deal with the straight sections on either end of the half circle.  Once bent you can then cut any extra material and the straight sections off.  

    Do not to forget to build a bending fork to fit that project with a proportionally longer lever arm.  It will make your life easier. (grin)

    I am going to try to remedy the horn probably this coming weekend and make it a little less blunt so its a more usable.

    May I suggest that you make a drift of the size you want and use it for a while.  This will prove that is the size you need.  Change or modify the size as needed.  When you finish you will have the exact tool for the bottle openers.  It would seem that you would have to make a lot of bottles openers before you permanently modify and dedicate the anvil for the same task.

    Look at the working end of a pick as a starting point.  There are other tools that are available that may work like a store bought drift, or a bolt that can be hammered into a drift. May be able to find a piece of pipe of the right OD and taper the rest.  Consider a two stage process, one to start, and one to finish the size you need.

    Use all this as a reason to get a second anvil with a horn the size you want for this one job.


  11. When there are fire bans, it is just too hot, or other reasons you can not build a fire and forge, what do you do instead to stay sane?

    The temperature has gone above my threshold, so I work early of the mornings, or late afternoons to avoid the heat of the day.  The AC in the house and modeling clay has added several pages to the note book of ideas.  Searching and researching the site has helped but we need more ideas.

    What do you do to stay busy when you can not work at the forge?
