If you look close to the bottom of the stack there is a yellow something taped around the circumference. Wazzat?

If this is for mounting a leg/fin it's a long SOB. More likely a utility raceway, but perhaps too wide?I've been expecting full body chines ever since I saw those struts on both the tank section of Mark 2 and the fairing section of Mark 1.I'm not an engineer, but I would imagine the pluses and minuses for that could be:Plus:- Adds rigidity to the structure- Provides more drag, and more liftMinus:- Chines would suffer greater heating, so might need to be cooled or made of some other material (i.e. more complexity to the design)- SpaceX tries to have a solution provide two benefits, such as fins also acting as legs, and chines may not provide that- Are they necessary?

Zoom in on the rings. Some rings have yellow writing on them that says "scrap" so the total of usable rings may be lower.

Chine is incorrect terminology, a chine is a sharp change in the angle of a hull, cross- sectionally.The correct term is sponson, which is a purposeful bump out either in a single location or the length of a hull.

something curious can be seen on this pic, most rings have a "brushed" like, more matte finish, but at least two are polished. different suppliers maybe? perhaps different thickness?also, all of them appear to have a smoother surface and less wrinkles than the stacked rings, however maybe that's just because they haven't been welded onto each other yet.credits Farriele Mohan @FarryFaz on twitter
The metal sheet used for these new rings comes in a tightly wound roll covered in white plastic wrap. You can see some of these sitting around onsite.

This is aerospace terminology, not ship building.Aerospace has so far been looked upon as a cutting edge extension of aviation but SX is pushing in a direction that really has overlap with ship building. What is a finny thingie by any other name? It’s still a finny thingie.I’ll shut up now. Phil

The staged rings on the ground are presumably for Super Heavy and they have been created from one long strip of stainless steel and formed into the ring. If you look closely, you will see that on those rings there is a single weld joint where they connected the two ends of the sheet.
