 |

|
Hi people! I was at a medieval event few days ago and I let our archers shoot two arrows at my wedge riveted mail between the mail and target was only my two layered aketon. The mail was pierced. Actually, in both cases, rivets failed. Mail shirt is not Indian made and I thought it was a high quality product. But I don't think mail should be so easily pierced by an arrow shot from 45lb bow even if it wasn't placed on proper gambeson and on a giving target. What do you people think? Is anyone able to provide a high quality, authentic piece of mail, at least 20cm x 20cm for testing?

Perhaps this: link
He, Mike Loades, did some tests with Eric D Schmidt mail if I recall... but I don't know how to find the video!! I think it was shot at University College London.

Isak Krogh is specialized on making historical maille. I've seen some of his stuff and heard VERY interesting stories about its durability.

It has been a while but last time I talked to Erik about this he said that the riveted section isn't where the failures usually occur.. When the link breaks it usually happens elsewhere along the wire. A properly pierced and peened riveted overlap should result in that section being the strongest part of the link.

I really think that the mail should have held up, but more info is needed.
What type of arrow head was used? Was it a modern broad-head?
What a bout the shaft? Wood, aluminum or fiber?
I tested a wedge riveted voider with a 40# bow using Bodkin points and wood shaft, but I used an old heavy quilt and denim jacket over a straw target, and the mail stopped the arrow from penetrating and held up six out of six times. I also tried it with a 55# compound bow and Muzzy triple blades on a carbon fiber arrow... Went straight through, busted rivets and tore up the quilt. The blades on the arrowhead looked pristine.

To Dan's point, Andreas Bichler recently posted a crossbow test against mail on Facebook. The bolt pierced mail and underlying padding up to the fletching. Interestingly, the broken rings were the solid, punched ones. The badly-riveted, Indian made, round wire rings deformed.

The solid links on Indian mail are way too thin.

Intuitively this feels wrong to me. The rivets are much thinner than the main link material and although their mode of failure would be shearing whilst the ring itself would fail in elongation, I would have thought that the links would be stronger than the rivet.
Any engineers out there who can explain it?

Wooden shaft, sport bullet point.

I'm contemplating about trying it once more with proper gambeson either under or over mail, but I think rivets are simply inadequate.
