  1. I have a spray bottle filled with water and a bit of dish soap. I spray my gas line from bottle to burner on a somewhat regular basis, checking for bubbles. I hate surprises.
  2. These are sometimes called "Haberman tongs" after the great Czech smith.
  3. Please be advised that if you're going to forge outdoors, the Frosty burner is a bit iffy with strong breezes. What will really kink things up is when your exhaust coming from the front of the forge gets sucked into the burner intake - you'll have a sputtering and stuttering burner then. I've largely solved this by installing a sheet metal guard that keeps the exhaust out of the burner intakes. The current shield is made from a christmas popcorn tin (lid and bottom removed). the tin is wired to the top of the frosty burner.
  4. The T-burner is particularly fussy about operating outside in the wind. I took one of the popcorn tins that are typically sold around Christmas time and made it into a wind screen to protect the air intake of my t-burner, as it's running on a forge outside, under a maple tree in my back yard,.

    Flame jumping

    I'm going to take a guess and say you don't have a flare/flame holder on the end of your t-burner. I had the same jumping - I put on a bigger flare and it went away.
  6. Regarding parts - depending on where you live, you may not have easy access to a store that will let you look at plumbing fittings - so if that's the case, McMaster-Carr or Grainger is the next alternative.
  7. A soft firebrick for the floor is not a good idea if you plan on using flux. Get a piece of kiln shelf for your floor - reasonably cheap, tough (flux resistant) and not a lot of thermal mass. As your forge is round, use some plain, non-scented kitty litter on the bottom of your forge before you put the kiln shelf down - it'll act as a leveler.
  8. You can make a one or two brick forge with a propane hand torch. It's not optimal, but it will work. You'll be using soft, insulting fire bricks - I'd recommend the ones rated for 2600 degrees F - you can buy them at Zoeller Forge or from Axner Pottery supply, or EBay. The soft brick can easily be carved out to make a small heating chamber. I'd recommend instead that you make a coffee-can forge and make a 1/2" frosty t-burner, you'll spend about as much money over the course of a year and have a lot more versatility. PM if you want to discuss further.
  9. Acklands Grainger (which appears to be the Canadian version of Grainger Industrial Supply) should suffice, or McMasterCarr, which I believe will ship to Canada. Here in the USA if I order from Grainger but pick it up at their store, I don't pay shipping - excellent source for plumbing parts and hardware not carried at the big box store.
  10. Regarding your t-burner going out and then relighting. The t-burner is a very stable design, but if the exhaust from your forge is getting sucked into the air intake of your burner, you'll get stuttering or intermittent flame. I solved that (for the most part) by taking a Christmas popcorn tin, removing the lid, removing the bottom, and wiring what's left as a kind of wind screen around the top of my burner. I forge outside, so the prevailing breeze in my area blows the exhaust out of the front of my forge up over the top of the forge, into the air intake. Installing my wind screen got ri
  11. If it's really 1018, then it really doesn't have enough carbon to harden for an edged tool. I'd try it as a stump anvil or set it into a cylinder of concrete and see how it does as a knifemaking anvil. I'll defer to the hammer makers on IFI, as I've never made one from scratch before.
  12. The steel doesn't get hot until the entire forge gets hot - so if the refractory is a heat sink, you'll spend 45 minutes to an hour getting the forge hot. After that, you're in good shape, but that's a lot of propane for the average hobbyist who forges two hours a day on the weekends (if you're lucky).
  13. To amplify on Latticino's comment - hard fire brick is a heat sink. Your steel won't get hot until until the entire forge is hot.
  14. okay, I'll bite, how do you test the hardness of a hammer? I watch some Brian Brazeal videos where he's using his 3# rounding hammer to smite his tools (eye punch) and it makes me cringe.
  15. Unless you're planning on using it as a hand torch, how it burns outside the forge at 20+ PSI is rather irrelevant. Once you get it into the forge body, you'll have some back-pressure, which will make the performance of the burner a bit different. I suspect in the forge you'll be able to go to 30 PSI.
