  1. I used to drive past the place for work when I was still in school even had a after work party hosted there. Its a really nice place for seeing some of the bread baskets heritage. I hate to see that its gotten to the point people are stealing from museums/heritage sites and hope they are able to recover their anvils.
  2. From what I've read and old picked up knowledge its kind of dependent on a number of things, but it should be straight forward with a air compressor motor. If you have a volt meter you can check the terminals for a charge and if it does you can short it with a insulated wire. It just takes time as its not a instant discharge as they sometimes have limit discharge resistors so you might have to let it sit shorted for maybe 5min then check it again. Hopefully someone more experienced can come on a give a more technical and safe answer.
  3. Hello all, I have been working on my second version of a blown oil & gas burner for a furnace and wanted some opinions on the baffle/fuel nozzle mounting plate. So the burner tube is 2" pipe and I need to have the nozzle at least eyeballed centered which requires something in the tube to hold it. What I wonder is do I need to make a full plug with holes drilled like the diffusers in ribbon burners or can I just drill a hole in flat bar leaving the sides fully open. I believe the flat bar would allow more air flow but might make some fluctuating turbulence instead of
  4. Inswool HTZ is rated for 2700 but mixing "insulation" types means the 2400 standard is good enough. The 2700 wool would be good for a more consumable furnace with just a containment coating.
  5. I know there is options below 1018 just hard to find 1008 was just one I was pretty sure a real thing as I didn't want to go down the sub .18 rabbit hole at 2am. I also saw the gokunantetsu and since it really doesn't turn up anything in a western based google search I have the feeling its their version of low carbon steel since the differences in language makes some things more specific than how we think of them in English. My feeling is its either a very low carbon steel or a cleaner wrought iron since "pure" iron .02 or less is its own word I think it just might be one of those reginal spec
  6. I do know I've watched at least a part of a documentary that covered this a bit and from what I remember it is just "mild" steel. Hopefully someone has direct sources as I take most documentaries with a grain of salt when mixing historical tradition in modern times especially when there is a lot of mythical fantasy about the topic. What I mean by "mild" is that there are different standard of what mild steel are and I know US vs Europe has some differences let alone Asia. That is without each knife maker or steel maker having their own blends as mild is just a generalized category as you know.
  7. I have been happy with the Ameribrade I have as it is a definite upgrade from the Grizzly we have at least and the cost/performance so far seems to be good.
  8. If you want interesting to look at that isn't nessisarily exotic woods then I use Rocksolid Scales here in IL https://rocksolidscales.com/ He tends more towards scales and less towards blocks so if you were looking for blocks then might not be what you are looking for.
  9. There are quite a few options out there and a lot depends on if its short term or long term storage. Oils are best for short term as they are easy to remove and reapply where waxes are good for long term but might need to be removed for use depending on different preferences of the cook. What me and my coworkers do is for non-stainless is we develop the patenia and then its just making sure the only time the blade is wet is when its in use. If we need to do a preventative food grade mineral oil is our go to as its neutral and you don't have to worry about allergies really. I haven'
  10. Flame arrestors (I think that's the right term) originally at least worked by having a mesh screen too small for a flame to propagate past mainly used in lighting for mines way back when. So the size keeping it from moving is a thing but not really for forges. So i'm not going to explain the exact reason as I dont have the science only the likely aspects so take this with salt as its educated speculation on my end. There can be a couple factors keeping the flame from traveling up when in a low flow situation. One being that once the flame exists you have much less dense air so thin
  11. If its like a electric fence then more than likely it is being energized by the line.
  12. So if it was zapping you enough that you noticed it but it was just kind of a oh that zapped me a bit the most likely it was static build up. If it was energized by the plug there will be no doubt in your mind its energized when it shocks you. Either way no matter what replace the cord then try retesting with a new cord. Its possible that the ground wire has multiple breaks in it did you test the positive and negative wires as well and get null?
  13. I have found that when I get the idea to work something that isnt steel or alloy of steel I look if its used in jewelry. If yes I look at how jewelry makers work it and can give me hints on what can be forged and what is cold worked. It wont always answer my question or give me much guidance but usually points me in a good direction to start looking before dive into the forums. It can be forged at least since it is one of the materials used in Mokume-gane but like you noticed its a lower temp and can be problematic. Its really how much effort you want to put into learning how to do
  14. Thanks Alan my brain kept trying to tell me degaussing was the way to go and I had to keep reminding myself that's magnetism not static. There are like billyO a Alan said different ways to mitigate or prevent a static burst when using a belt grinder. How effective and worthwhile each one is is up to the end user. The key thing I would say other than always inspect your cords or any exposed wiring before you use them from plug to machine terminal is its worth it to keep a cheap multimeter around when you have electrical machinery especially as it ages or gets knocked around.
  15. Since most work shoes and really shoes in general have rubber soles it makes building up a charge really easy. Grinders are really just motorized rubbing a balloon across the carpet when it comes to static if you are insulated from the ground yourself.
