    minimizing the weight of the scale vest

    Lol, it's industry standard for lifting chains, more a rule of thumb than the actual engineering specs and it's based on UTS rather than YS so it's not an apples to apples comparison. As for the chainmail industry most operate under ISO 9001 to the best of my knowledge. However, the safety products they make will generally be certified to various standards for international markets. In America it's generally NIJ-0115.00 for body armor, for gloves ANSI/ISEA 105.

    8x is a good margin, industry standard for chain is only 3x so you should be good.

    Newby question about chainmail suit

    Generally speaking that's correct, some galvanized is quite strong but it also has issues with discoloration and smell of the zinc coating.

    Newby question about chainmail suit

    That should be a good ring size for your purposes. What kind of steel are you using? It sounds like you want this thing to last and not require a lot of maintenance, if that's the case I'd stay away from galvanized or annealed steel.

    minimizing the weight of the scale vest

    Well, it doesn't hurt to ask TRL and see what they're willing to do. Another option would be to use a welder if you have one, regular stainless is plenty strong even with a tack weld.

    You have to make a custom order for the spring stainless ones, not sure how it works right now with the change in ownership. When I worked at TRL I would just coil and cut them myself. They will be more expensive though, that's the real trade off for lightweight armor. Making your own rings would be the least expensive option there.

    Torch Troubles

    There should be fuel flow and pressure adjustments on the torch, maybe play with that to make sure your air to fuel ratio is good. Cheap butane torches do tend to break a lot, I've had some success with the Bernz-o-matic ones in the past. Based on this testing video the blazer brand seems pretty durable, might be worth a try.

    minimizing the weight of the scale vest

    The best way to minimize weight is to use stronger rings and a larger ring diameter combined with smaller wire gauge. This minimizes the amount of scales per area which makes up the bulk of the weight. For example if you use 18g 5/16 spring stainless instead of 16g 5/16 aluminum the rings will have a similar weight and strength but because of the springback in the steel rings the finished piece will have about 25% less weight of scales. Another option is to use split rings, the #7F ones from worthco.com work well with large scales. I haven't used TRL's split rings in a long time but last I did they were pretty terrible.
  9. Yes, thanks. I just assumed that sanding or grinding the steel in prep for weld/solder was being done. If it wasn't, then it definitely should be.
  10. I would suggest brazing the copper wire on with a bit of brass or silver solder and use borax as flux, that should make it stick. You'd need to use a torch as your heat source instead of a soldering iron. You could also try to use your jewelry welder to weld a small bolt onto the pliers. It would probably take multiple welds to get a decent electrical connection though. Brazing is likely a better method.

    Just a note regarding your ring size, you didn't specify SWG or AWG but it could be pretty tight for functional sleeves. Most historical pieces would have thicker rings covering the chest and thinner ones for the sleeves and skirts.

    Sterling Silver

    That ring size is going to be pretty strong, as long as it's loose fitting and non-supportive I don't foresee any issues. On the other hand, it's going to be much heavier than the 8-9 oz you originally posted.

    Sterling Silver

    As long as it's soldered it won't deform under it's own weight. However it may deform as a result of strain from movement. Please post the ring sizes, the design, the temper of the wire and the relevant measurements for your wife if you want a more specific answer.

    Sparkle Pulse Welder Connector?

    Hi Lunitari, sorry about the late reply I don't check this forum often. The connector you're looking for should be a GX12-2. https://www.amazon.com/Aviation-GX12-2-Female-panel-Connector/dp/B06ZZ5NJ65 As far as the welds go you do need argon for this type of welding with titanium and you're on the right track with a solenoid valve. It will also be helpful to have a laminar flow device and a cup to hold the argon around the weld area. Those will allow you to get good welds with a low flow rate and keep your gas usage to a minimum. I find it convenient to adapt TIG welding accessories for this type of setup. Be sure to set your gas nozzle pointing upwards, this will keep the argon from draining out under gravity between welds and you won't need to use as much gas to purge the lines each time.
  15. Hi Fenris, putting together the resistance welder kits was a lot of work for me and once we started MailleTec I just didn't have the time anymore. As far as I know there isn't anything comparable being sold anywhere but if you get in touch with me at MailleTec I can help you to build something similar.
