    Matte vs. Shiny Titanium

    If you buy wire instead of rings then shining it up is pretty easy, just pull the wire through some fine grit sand papers. Loose rings also tumble up sort of okay with steel shot in a rotary tumbler, they'll stay dull on the interior half. Run it with citric acid and detergent afterwards to remove iron contaminating the titanium surface. Alternatively you could also make titanium pin shot from wire. It works pretty well. Once the rings are woven they just won't move freely against each other due to the rough surfaces and tight weaves so tumbling is a no go at that point.

    Platicoat

    I've found heat shrink tubing to be a better solution than any other coating option. For myself I just smooth out the plier faces with some sandpaper and don't grip too tightly.

    German Silver

    Hey Jamison, since nickel silver was originally developed to counterfeit Sterling silver it has a very similar appearance even when tarnished. If Sterling is out of your price range you might also consider silver filled or plated wire which is widely available.

    Matte vs. Shiny Titanium

    Unfortunately titanium is normally acid etched at the mill after being drawn, this leaves it with a dull grey surface. The etching is very deep and can't be easily removed once the wire is made into rings. My best advice is to consider doing a subtle inlay or just randomize the new and old rings.

    Wire

    My preference would be for the 1.25mm unless the wire is very soft, in which case the 1.6mm would hold up better at the cost of extra weight. I scanned the Merriway listings but didn't see the temper of the wire anywhere. It would be prudent to call them looking for more info or just get a small coil of each for testing first. I wouldn't recommend the 8-2 weave with butted galvy rings in any case, 4-1 will get you better results for less work IMO.

    Right, I won't waste any more time replying to you then.

    Chinese Mountain Armor

    Seriously? I mean it's a decent looking bit of lamellar, but are you really so egotistical as to believe that you've solved this mystery? Your results barely even resemble the historical records and you have no archaeological evidence. This is nothing more than another guess and not a very good one at that.

    Stitching two pieces of scalemail together

    I see, well TRL and I disagree about the correct ring size for scales. Those scales were designed to work best with approx. 9/32" ID. Using 1/4" rings makes the weave slightly stronger but also much heavier, less flexible, etc. The basic form of the seam should still work but you will need to substitute larger rings in places to keep it from bunching up.

    Are you using rings from TRL? What's the actual ID of them?

    Making armour from steel washers?

    I just put the numbers into my ring strength calculator, but the basic idea is cross sectional area of the wire multiplied by UTS of the wire. Edit; Actually, it looks like I was wrong too. My calculator was set for square wire, for round wire it's about 215lbs. So just to double check that would be (((0.048i/2)^2)pi)120,000lb/i^2= ~217lb

    You only have to break one, but your math is still off. You're using yield strength of annealed stainless bar stock, you should be using UTS and 120Ksi is typical for commercially available rings and wire. Annealed stainless wire is still usually about 100Ksi. The finer the wire is drawn the higher the baseline numbers will be due to grain refinement of the metal. Typically you'll get a mechanical advantage of about 2:1 for most blades that can penetrate maille armor without breaking, but the majority of modern carry knives or improvised blades will just break or blunt immediately. A good dedicated stabbing weapon would get you about 3:1, say a spear or a dagger. Weapons optimized for armor piercing can push 4:1 but you will never likely see one of those. These mechanical advantages apply against butted rings as well, so it's still going to be about two orders of magnitude or roughly 100x stronger, no matter what. You're also wrong about crack propagation, that doesn't occur unless the wire is very hard, especially with stainless alloys. Also keep in mind that any padding or give to the armor will bleed off a large amount of force. Historical maille armor averaged about 18g to give good protection vs spears and daggers but with modern alloys and welding 20g can be just as strong. In practice 22g is enough to defeat most attacks with a modern knife and most stab resistant armor in use today runs from 21g-24g wire depending on the application.

    I hear you, I have moderately protanomalus vision myself and it can be a real pain. If you're still having issues I can grab those pieces and mark them up with more vivid colors then reupload for you.

    Yeah, there are scales added in, they have a silver colored backside rather than the bronze color of the rest of the scales. Similarly the rings used in the seam are brass rather than stainless. Have you downloaded the image so that you can really zoom in on the details? I find the forum gallery software to be substandard for viewing images, which is ironic since that is its only purpose.

    You should probably just stick with the pattern that I posted. To the best of my knowledge nobody outside of my factory has ever done these seams before. There might be some minor differences since I'm using welded rings with an aspect ratio of ~9 but it should still work I think.

    Making armour from steel washers?

    I just did the math really quick, it should take 275lbs of force to break open a welded 18g stainless ring. That's probably closer to two orders of magnitude more.

    It's safe to say that the welded piece would be an order of magnitude more stab resistant, all other things being equal. As a rule butted mail has very little stab resistance although it's pretty good against slashes.

    I've tested a lot of armor and I have to agree that anything that isn't welded won't be very stab resistant. As far as cost goes, how much is your life worth? I would suggest that you at least call my company and get a quote on a stab resistant shirt. It'll be far better than anything you can make yourself and probably not as expensive as you think. If you do be sure to mention to whoever you speak to that I offered you the highest discount rate.

    Getting back into it, a few questions about scales.

    Well there wasn't really a lot I could do in that case, the costume designers thought that they knew what they wanted and were very insistent on their "vision". Being able to have the actress in for some test fittings would possibly have helped some but the whole idea of a scale armor gown is just not practical.

    Those ones are small, it isn't built to scale. Best to just ignore the sizes and build the pieces to an appropriate measurement.

    Three is a pretty close approximation for most peoples shoulders, you could go up to four for better freedom of movement in some situations. The way these seams are constructed there shouldn't be any issues with scales sticking up, you can definitely make more flexible expansions but these are the smoothest looking that I know of.

    You're welcome. For larp you'll definitely want to fill the armpits in with maille or just leave them open. Scale armpits don't move so well. I never recommend sleeves going past the elbow either. The dress was a costume for a movie and it turned out to be cumbersome enough that the actress wouldn't wear it.

    Getting back into it, a few questions about scales.

    The top and bottom pieces are the torso, neckline to the right, sleeve on the left. The longest seam runs from the neck down the trapezius muscle to the acromion and transitions from an expansion seam to a straight seam just past there. The shorter seams run from the neck down into the armpits on the front and back. Here's a link to some pictures of a dress we made so you can see the technique in situ. https://www.facebook.com/media/set/?set=a.760886937333833.1073741827.133364950086038&type=1

    Here are couple examples of my most basic shoulder pattern. This technique can also be used for more advanced styles. Spaced out for smooth curves, combined with contractions for form fitted tailoring, etc. Let me know if you guys have any more questions about it.
