Wisby Type 1 Riveting question.

Wisby Type 1 Riveting question.

I am helping a new fighter in our group upgrade armor. We are building him a (slightly modified) canvas covered Wisby type 1 coat of plates. The COP is the one with 3 vertical plates on the upper chest, 4-6 horizontal plates on the belly and assorted vertical plates around the sides. We will be adding spine protection as the original does not include this.

I was looking at the rivet holes in the drawings of the extant pieces. I understand the intended direction of overlap for the belly and the sides since it is obvious from which side the plates are riveted on. The upper chest has me confused.

The central chest plate in the extant piece only has 2 rivets in a vertical line. This would imply that the side chest plates fit between the canvas and the center plate. This means that a thrust that hits the center plate and penetrates the outer layer will slide sideways until it hits the edge of the next plate and then MAY push the plates aside and penetrate the upper chest. A more logical approach would be to layer the plates like roof shingles so a thrust to the center plate would slide all the way to the edge and enter the shoulder at a non vital location. The lower torso is set up on this principal so the technique is obviously understood.

The questions:

Am I interpreting the drawings wrong?

Is there a functional reason why deflecting a sword tip outward is not desired in the chest region?

Is there a mobility reason for the overlap to occur in this direction?

Does anyone have any experience with their COP-1 that they wish to share that may be relevant?

Thank you,
Sean

I believe you are interpreting the drawings correctly. The mobility issue comes from forward movement of the arms, which pushes the chest plates together. As to the issue of protection, I am reminded of a lesson taught long ago by David Counts: Remember these are the armors worn by the dead guys.

Check out the how to build the COP on the GAA website, shows it in detail with great pics.

Cheers,

You are right, the plates are arranged so that they don't entalge the movements of the arms, is better a (ipotetical) fault in the defence that allow a greater mobility than viceversa. And Wisby CoP don't show great battle damage, so we can assume that they were quite effective, and probably for this reason "the dead guy" have usually severed limbs and head broken in pieces.
