im sure that the sca require 14 g. i personaly would use it and nothing less. depending on type of arrow head and poundage of bow, most will penertrate even 14g.

ive wondered the same thing for a while, although i would go as thick as i could while still trying to save weight. how does aluminum do in a strength comparison to steel of the same gauge? thats what ive been wondering. will aluminum of the same gauge of steel do good in a destructive test? ( bash it with a massive axe) better or worse than steel? anyone know?

im not a expert but i do know that you would have to up the gague in the aluminum to compare to steel. it dose not have the same strength

As we say in (in my case biomedical) engineering: "Nothing ruins a good hypothesis like an experiment." Two years ago, as part of teaching an honors physics course, but more than anything to address my own curiosity, I ran a test. 16-ga. knee cops struck dead center by bolts from a 225-lb compound crossbow with hardened steel field points, range of five yards. (Yes, read that again, FIVE yards. "Blast screen" construction was the time-consuming part of the whole procedure.) 50 attempts. Zero penetrations. "When in doubt, suck it and try it."

i think 14 gauge aluminum would do very well against most swords,axes,machetes, and most other hand weapons.

I'm looking for an answer to a common question. What gauge of steel plate can take what punishment ? We got in thinnest to thickest you can get commerically: 19g, 18g, 16g and 14g. So what one is best for say what application: Re-enactment: SCA Rattan Steel Blunts (Half Force) Steel Blunts (Full Force) Historically Real Attack: Blade: Blunt: Arrow/Bolt: I'd just like some imput, cheers I can't answer the others, but for SCA Rattan... 16Gg Steel for the helm is the minimum requirement. My helm is 12 Gg, but it was spun rather than hammered, so the strength is reduced. It has held up quite well. Most people run around in 14 or 16 Gg helms and need a replacement about every 7 years in my current and my previous groups. Less often for the better fighters, of course... As for body armour, to my knowledge, there's no minimum requirement for thickness of the metal or leather. Plastic has a minimum thickness, but then, it's plastic. I know a guy with 22Gg aluminum chain. I'm planning 20 Gg steel scale. I would imagine that plate would want to be thicker.

Oh, in RL. I'd be happy with my helm, happier if it was hammered rather than spun. And I'd probably up my scales to 16 Gg, though I might stick with 18.

just out of curiosity how functional would brass be?

Brass could be functional, but I seem to remember that the Panoply of a greek hopelite weighed in at like, 50 lbs. I'd say functional, but it'd be heavy to get function out of it.

Not sure about brass. Has a reputation for brittleness...but again, don't just go on rep. Brass is fairly available and not prohibitively expensive, so .... if you want to know how it'll hold up for your purposes test it under the conditions of your purposes.

Then you have to take into account, what sort of steel it is. I hear that 'spring steel' can be made of the same gauge but actually be lighter than the 'usual' steel that is used. Also, was it hot-rolled or cold-rolled, that makes a difference in tensile strength as well, but you'd have to take that up with an armorer I believe.
For the aforementioned applications, rattan would require at the very least 18 gauge, 16 for the helm; I've seen 14ga and 12ga and in a few rare cases, 10g for helms. I imagine those would be a bit heavier of course.
For my kit, I went with 16ga chainmail and plate accents (shoulders, arms). But I only wear mine, I don't fight in it.

What gg steel you use depends on what Type of steel (stainless, carbon, spring, cold-rolled, hot-rolled, etc, etc, etc) and what Type of armour. Plate wants heavier Gg. Chain probably can get by with the lightest Gg of all the armours.

We used 16 g steel for half speed blunts in re-enactment, that does tend to end up pretty heavy, we weren't using aluminum though, real steel for period accuracy.

im sure that the sca require 14 g. i personaly would use it and nothing less. depending on type of arrow head and poundage of bow, most will penertrate even 14g. Actually the requirement of the helmet is only 16 gage, but that is very prone to getting dented up easy. Some Kingdoms hit harder then others. In the East we hit pretty hard. 14 gage is preferable. Some people go as thick as 13 or 14, but I think that is a bit too heavy. The gage used on the elbows or knees tends to be 16 or 18 gage. Anything thicker and the weight starts to add up. The rest of the body is even lighter. I do not believe that most arrows or bolts will penetrate 14 gage. Good chance of penetrating 18 gage if they get a good shot. Historical plate was only 18 or 20 gage and sometimes 22 gage. It was hardened and tempered to add strength, but it was also disposable and replaceable. Historically, men lived in their armor, marched in it for days and stood hours of guard duty... they were willing to accept a higher level of risk. Today we only wear armor for a few hours at a time. When we practice we expect to get 20 or 30 times and we expect it to last at least a few years. For this reason we favor more durable armor. We wear much more armor on on heads then was the historical average and probably less on our bodies. I don't want to any traumatic head injuries. The weapons are not sharp, so I can take a hit to the chest, leg, upper arm without serious risk. On those areas I wear lighter armor.

Rule of thumb for strength to weight ratio between aluminum and steel, 2 X thickness for same strength at 1/2 the weight

Experience is everything...when in doubt, try it out! Besides, what works for you may not work for others, and vice versa. Let us know what you decide to go with.

I have been thinking about making a chainmail hauberk from 14 gauge steel. I want to make it with long sleeves that go down to my wrists, and the bottom of the hauberk going down to my knees, or close. The front of the hauberk below my waist would be split, making it easier to ride horses and move in an agile manner while on foot. Does anybody have an estimate of how many rings it would take, and how much it would weigh?

That's going to be a LOT of weight. Seriously, go with a lighter gauge. Somebody else said in another thread that you'd be looking at 20,000 (20k) rings.

I might go with 16 gauge, in that case. 20k rings, seriously? How many feet of wire would I need?
