Rotating Socket that attaches the upper arm to the shoulder?

[NoBSSurvival]

I was wondering if anyone has a guide or information on making the rotating socket that attaches the upper arm to the shoulder in armour?

No that is not what I was talking about. I meant how there are some armours where the upper arm rotates inside of a tube like part of the spauldlers. Like in the example I showed.

We call those "turners." Essentially dividing the rerebrace into upper and lower halves. Latter sixteenth century, I believe?

Early 16th c. through the end of arm armour.
And they are constructed several different ways. The normal way is a flange on the top of the lower plate that locks into a "bump" on the upper plate.
There are other ways to do it, mostly used in the early part of the 16th c. but sometimes also done later.

What do you really want to know?

Are you interested in turning joints in general, or that one in particular? The reason I ask is that the one you link to is rather unusual. It seems to have four rivets holding the upper and lower parts together. These rivets work in long horizontal slots in the underlapped plate. I have never seen a "rivets in slots" type that had four rivets. They typically have three. With four rivets, the total rotation must be something less than 90 degrees. This is a bit restrictive. With the more usual three rivets, the rotation can be just under 120 degrees, which is all the motion you really need, provided you set it up so that the neutral position is in the right place.

The non-rivet types typically have sort of "bearing" made by a turned-out flange on the lower part engaging a circumferential "welt" in the upper part. These have full 360 degree rotation. Nobody needs that much, of course, but that's what you get.

In addition, there are less common types of turners involving internal mechanisms, but they are really varients of the basic types.

The important thing about any of these turners is that the cannons must be quite round for them to work smoothly.

Mac, I see all of the rivets, and I would have to guess that this is likely constructed the way you indicate. That is the most likely guess given the data. But there are some other weird ways to do things that involve rivets in some weird places. For example, this one:

is built really strangely.

Depending on what the actual desired result is, I would suggest going with the most normal flange in bump version of things, unless there is some particular piece that is being replicated that was done differently.
