  1. I'd repair it, but I would be able to do the repair myself so that changes the economics. Shouldn't be too hard to keep the face below 400 F or so by using a temple stick. With that much mass, temperatures are not going to be changing very fast. I had to laugh at the don't risk damaging it comments. As if breaking off the heel was not damage. If someone had repaired it 50 years ago, would it be worth less, or would it be part of it's history? Even if it was somewhat botched. As long as the temper wasn't drawn on the face it would be no worse off. If it was ugly enough just cut it off again and you are back to what you have now. Not mine so what ever you decide is what is right. Just posting my opinion. I've had customers hand me a broken, beat , distorted, often repaired and broken again, piece of hardware with glue all over it, and tell me not to ruin it. Hahaha. Edit; Just saw that you have another anvil. I guess if you have the room to have both anvils in the proximity of the forge there is no need for the repair, but also less need for the broken anvil.
  2. Stuck in the city. Now what?

    Check makerspaces in your area.
  3. Why cant I drill into this metal?

    Grade 60 rebar can easily get hard and brittle. Rebar does not have a specified chemical composition, only a minimal yield strength. I made my first pair of tongs from grade 60 rebar. They came out fine, but when trying to cold set the bit just a small amount one side snapped. I arc welded the bit and still use the tongs. You didn't do anything wrong, except for using rebar for tongs.. You may be able to anneal the tongs to drill the hole, or hot punch it, but that still leaves the problem that Charles pointed out with future quenching. I would recommend hot punching the hole and using them, but do not be surprised if they snap on you at some point.
  4. You may also tell him that if he did get something down a boot or shoe, stepping into the slack tub would not be a bad idea. I've heard of people who were badly burned, while trying to remove a boot, not even thinking of this. I'm not sure that I would have either.
  5. First Gas Forge Design

    I've never seen any evidence of Alec using less than both of his burners in his large forge.
  6. Damascus steel

    If you're going to be making billets and folding or cutting and stacking you will be doing a lot of drawing out. Drawing those pieces out to 1/4" thick or so to start will be a small part of the work. I would be sure that I was proficient at welding chromium alloy steel before attempting A billet with those pieces. I have no idea how those pieces will work for damascus, but my gut feeling is that there might not be strong contrast.
  7. I meant that I wish that I could hold the pieces personally for a more complete appreciation of your work. Thanks for the anvil dimension, I was guessing close to that.
  8. Very nice. I wish I could see the pieces in hand.
  9. Thin damascus project

    The modulus of elasticity (flex for a given load) is identical for hardened and unhardened steel up to the yield point of the unhardened piece. Since you don't want the spatula to ever take a set (yield), I would harden it. The hardened steel will be able to flex farther without taking a set . 3/32" to 1/8" would be a good place to stop forging IME.
  10. Coal forge trouble shooting

    Rocky Mountain Smiths. I'll shoot you a message.
  11. knife from giant rock boring bit

    Cut off a piece of the shank end and make sure that you can harden it. Assuming that it is hardenable, you may be able to untwist it and upset it to get extra thickness.
  12. Coal forge trouble shooting

    There is an open forge in Berthoud tomorrow.
  13. Forges 101

    Hmmm... I have zero secondary air coming into my forge around the burner. The refractory is sealed right against the nozzle. I did open the choke a bit from how it was adjusted for free air. This might explain why my mild steel nozzles have such a long life.
  14. Coal forge trouble shooting

    ^^This^^ Scruffy, I'm sure that I'm using the same coal as you. If you pile on green coal it will be very smoky. You can start your fire with a bit of charcoal and let the coal coke on the outside of the fireball before moving the coke into the fire. I personally don't like to ever put green coal into my fire, but some do.
  15. Where do you put your Propane tank?

    I used to have my tank on the cart under the forge. I've since moved the tank outside with rigid pipe through the wall and up to the ceiling and a drop hose to the forge. There is a shut off immediately after the pipe enters the shop. I feel much better now.
