  1. Sorry, that thread is in the Beginner's place:
  2. Yeah, that sounds like an explosion waiting to happen. If they were propane burners you might get away with it (see the pinned thread about simple forges above), but Coleman fuel is WAY too volatile to be used near that kind of heat.
  3. They (the ones from the American southwest, that is) are almost always full tang with a central forge-welded bolster as well as the one at the blade, and often one at the butt as well. Like this one: Thick, too. Like up to 3/8" at the hilt. Man, I miss Chuck Burrows when stuff like this comes up. I checked the posts he made in 2012 with almost all of his pics of antique belduques, but the links are broken since they were hosted on his site.
  4. That is my understanding as well. The one potential problem is if the peening of the tang has locked the nut in place, in which case you'd have to get the bits of tang out of the slot, tighten the nut, and re-peen the tang. Maybe use a little boiled linseed oil to try and expand the shrunken leather spacers first?
  5. It occurs to me also that Hitachi White is designed for water quenching, or at any rate it is a very shallow-hardening steel. Could also be that only the exposed edge fully hardened. It (#2) has enough carbon in it (1.05 - 1.15%) that it could lose a lot to the mild and you might not even notice. The mild is going to be (depending on which alloy) between around 0.15% and 0.25% C, so even if full diffusion has occurred the overall carbon is still going to be around 0.75-0.85%. I also thought about the one-sided iron/steel knives of Japan. The steel does fully harden, but it can be bent because of the support from the iron.
  6. Stihl, Husqvarna, or Jonsered? Or something else? I learned long ago to never buy a cheap chainsaw.
  7. Sounds like whoever did the welding may have hosed it. How thick is the White Paper? Carbon can move 1/16" in five minutes at welding heat. I can't explain why it both skates a file and takes a set, though... but my san mai experience is limited. Hopefully someone with more experience on the Hitachi steels will chime in, I've never used it. I have a small piece of Blue Paper, waiting for the right project.
  8. I have seen it done, but it's certainly not common practice. It may be more efficient, but the danger of it not relighting would keep me from doing it. Not to mention the extra oxidation you get every time you turn the burner off. Not a big deal for mild steel, but a dealbreaker on blades. I have seen an idler circuit built into atmospheric forges, though. It's an extra loop of fuel line with a needle valve and ball valve that drops the fuel input greatly, acting rather like a pilot light in a furnace. http://www.hybridburners.com/new-help.html#idlefull I have heard of at least one guy who used a solenoid to operate the ball valve so his forge was only on full blast when his foot was on a pedal.
  9. I never met him, but I have several picture of his knives on my screensaver at work. Sorry to hear it.
  10. European specs: DIN 1.1231, Krupps CK75 (Germany), AFNOR XC 68 (France), SS14 1770, 1778 (Sweden). All that said, C60 makes a good blade if water or brine quenched, that's what the late Bob Engnath used for his Japanese-style swords. It takes a great hamon, too. I doubt you'll find any car parts (at least recent ones) made from 1075, most are using 5160 or 9260 for the springs. Those little e-clips used to hold down railroad track are 9260 (if made by Pandrol), one of my favorite steels. Relatively easy to forge and finish, tougher than most other steels. It has to be oil-quenched.
  11. That's what I was thinking, 1075 or something similar.
  12. That bowling ball carcass material is pretty spiffy for plastic. Looks almost like amber.
  13. Looks good! Too bad about the router base collar. I hate when an otherwise decent tool is crippled by corporate greed.
  14. Bummer. I feel much the same as Bruno about tool theft. That's just low.
