  1. Yes, annealing is what is meant by normalizing. You hold the steel maybe 50C above critical temp for long enough for the grain structure to refine. How long and at what temp depends upon the type and thickness of the metal. For something like 16 guage rings I wouldn't imagine that would be very long.
  2. Curious: Should not the welded armour be normalized first so that you're dealing with as uniform a structure as possible, prior to tempering? Or is that superfluous, given that you're water quenching everything up to that same weld level of brittleness?
  3. A kit is a good idea, because you know that you're getting a tried and true size and number of the rings for the project. In addition to this TRL has a couple of calculators designed to help you figure out how many rings you would need, based on project and ring size. You could start with a kit and then, once you have gained basic proficiency with chainmailing, use the calculator to help in future projects.
  4. In the days I worked in computer manufacture there were a few times that we had to send out old style CRT monitors to have every inch of the interior copper coated, because they were to be used in security installations. Apparent CRTs could be "read" remotely by detecting the emitted frequencies, or so I was told.
  5. I've remade my first scale piece twice already and will be doing so for a third time, sometime soon to reprofile it and replace the aluminum rings with mild steel, by sections. It's not done until it's done. Doesn't help that I've dropped 40 pounds since I first made it. I can't give better advice than Paladin already has.
  6. Depends upon what sort of 'radiation' you're talking about. Microwaves are referred to as radiation and are blocked by a Faraday Cage. Want to block something else? Make your walls out of foot-thick lead.
  7. What you're talking about is called a Faraday Cage. Aluminum rings would not provide a positive enough contact. You want to use something like fine copper mesh, soldered at the seams, well grounded, and protected from damage at floor level.
  8. In that design the back should be somewhat wider than the front, in order to allow proper mobility for the arms. It does look like the side panels could stand to be a little wider too, which would open the neck up a bit.
  9. If you drop the middle row of scales at the front of the neck hole, for about 4 scales, you could stabilize the edges of that with rings and then add lacing. This would allow the neck hole to open slightly wider to make it easier to get on and off.
  10. @Konstantin the Red - In my case it's costume, not functional.
  11. I wouldn't want to use it even for training with blunt weapons, because you need padding for that, but you could certainly use it to make an under-vest of some sort. That's assuming it's actually properly tanned. You might want to think about using it for something else though. Cutting into strips for ties, making medieval style boots, or the like. As for a gambeson, I've been trying to think of a reasonable pattern with which to turn a moving blanket into one.
  12. It's a bit slow but people still come around. Right now I'd bet that holidays and family are keeping people away.
  13. My first attempt at a cabochon using 3/16", 18 gauge stainless and a Moonstone. I ultimately had to make a spacer out of clear Worbla to take up the slack because one less ring wouldn't go around it and one more ring was too loose.
  14. I've only ever had this happen once, when I was tumbling some stainless with very small stainless pins. It has never happened again, even with the same combination. At the time I checked the sludge with a magnet and found that it was mildly magnetic, indicating that it had at least an element of the stainless in it. Unclear if it's the same with you. As to removing the "gunmetal" look I tumble in corn cob media afterward, to clean the surface of the rings.
  15. You're going to want all of that zinc gone and a nice, clean surface on those rings for welding.
