  1. On a forced air setup 1" pipe is fine. Forced air is the brute force approach, it is rather forgiving on the details. That type of burner should have no problem getting your forge up to welding heat. Wayne
  2. The big difference between plistex and ITC-100 is that plistex is a refractory mortar while ITC is an infrared reflective top coat.
  3. The fuel consumption of a burner is only dependent on how high you run it. It is easier to run a forced air burner higher, but they can be set very low also. Wayne Suhrbier
  4. I finally have both high and low temp HT salts back in stock. Hightemptools.com Wayne Suhrbier
  5. Hello. Hightemptools will be at the Alabama Forge Council conference in September. I will have supplies with me and I can also bring orders for pick up. I'm looking forward to seeing all of you there. Wayne Suhrbier
  6. The Kast-0-lites are kind of flux resistant. Mizzou will hold up much better and Bubble Alumina will hold up the best. I recommend covering the floor of a forge with either Mizzou or Bubble Alumina for forge welding. Satanite over inswool will not hold up well to flux, although it is great for the upper parts of the forge. Eric- I sell ITC at Hightemptools.com Nprovos- Great walkthrough of your process. Vaseline works great as a mold release also. Wayne Suhrbier
  7. An oxidizing flame is where there is more oxygen than fuel. In this situation there is free oxygen that can react with the metal and cause scale which doesn't weld. A reducing flame has more fuel than oxygen. In this case all the oxygen is used in burning the fuel so there isn't any left to react with the metal. A neutral flame if when the two are equal.

  8. Satanite and apg-36 are the two most popular choices. I like to coat the entire blade with a very thin coat and then put a thicker layer on the spine. Wayne Suhrbier
  9. The method I use for getting the interior welded is to weld a stub to one end and a handle to the other. When the billet is up to temp (as Richard said the core needs to be hot) the stub gets clamped in a vise and the handle is twisted using a monkey wrench. You can feel when it welds together. At this point there will only be the outside strands that need to get hammered together. Wayne Suhrbier
  10. At HT temps 1" of Inswool will hold in plenty of heat. 2" if you like overkill. Be careful if you use it loose as it sheds nasty little fibers everywhere. If you get inconel or monel wire to hage the pieces with you won't have to worry about the red strength. Wayne Suhrbier
  11. "If you don't already know, learn how to draw steel by using the back of your hammer to create grooves and then hammering them out. This also introduces a nice randomness into the layers." I prefer the edge of the anvil, but the outcome is the same. Keep that sucker hot at all times. Wayne Suhrbier
  12. If you are going to do a bunch of forge welding I recommend Bubble Alumina as it is the most resistant to flux. Mizzou comes in second. Cast the interior out of Mizzou and then put a 1/2 inch layer of Bubble Alumina over the floor. Don't bother putting your plisix (ITC-100) on the floor as it will get destroyed very quickly by flux.

  13. I carry a full range of refractory materials. Hightemptools.com Wayne Suhrbier
  14. Santiago, I am happy to ship internationally. Rigidizer on its' own isn't great, but will help keep the air born fibers down, better than nothing. I like to cast the floor on a vertical forge since that is where all the flux goes and it is the least crucial spot for insulation. Various castables insulate better than others. Generally the more durable the castable the less insulation it provides. Mizzou is tough, but a lousy insulator. Kast-0-lite 26 isn't as tough, but a much better insulator. What combination will be the best for you depends on how the forge is going to be used. Wayn
  15. My >guess< would be that with a traditional rectangle, not very well insulated forge, with the burners pointed at 90 degree angles, the use of multiple smaller burners would help to reduce hotspots. Wayne Suhrbier
