Small progress report:
-Two rings were brought inside the tent around 4-5am and stacked on the welding jig by 10:30am.
-A ring was brought to the tent around 10am but was returned to the ringforming station a few hours later.
-One of the Florida work stands was taken out of storage and staged in front of a tent.

Test stand was moved from out back to near the front of the big tent.
New holes in the ring stack.
The test tank belt was moved.

So Elon has a few updates in response to the article, "SpaceX wants to build Starships in days with off-the-shelf water tower manufacturing tech", which was based on a SpaceX director stating that "off-the-shelf water tower machines work really well for making rockets" and could build "a Starship in a day".
This isn’t quite correct. An orbital rocket needs precision that’s 3X to 4X better than a water tower, so super precise parts, fixtures & welding are needed. Suborbital is much more forgiving. That said, although substantial capital & engineering is required to achieve extreme precision, marginal production cost of the primary structure should actually be *less* than a water tower, because it’s built inside a factory in volume.

Elon: Yes, we’re tuning weld parameters to reduce puckering & building a heavy duty planisher to flatten & cold work the weld area
https://twitter.com/elonmusk/status/1225626494627651585Q: Are the barrels in the picture above just test hardware then rather than the first pieces of SN1 coming together?
Elon: No, they’re SN1. SN2 to follow shortly. Aiming to be a little better each time.

VIDEO: SpaceX teams are working at full speed to complete the Starship SN1 prototype which will conduct a 20 kilometer hop in the coming weeks. Meanwhile, second windbreak and launch site preparations are underway.

Couldn't sleep, so I thought I'd go out and watch them move Starship pieces around.
I really need a better night camera.

Nice catch, I was just about to post something! That three-ring stack was indeed shifted to the side of the tent visible from LabPadre and (I believe) placed on the stand that was moved there yesterday. Also looks like they're getting ready to move something with one of the cranes.

Thanks for the correction and apologies for any errors, Elon! Was the SpaceX director that said "[OTS] water tower machines work really well for making rockets" wrong, in that case? Or are COTS solutions viable but only if SX tweaks them for greater precision? - @13ericralph31
https://twitter.com/elonmusk/status/1225688871158968324 Unmodified water tower machines do not work well for orbital rockets, as mass efficiency is critical for the latter, but not the former. Hopper, for example, was made of 12.5mm steel vs 4mm for SN1 orbital design. Optimized skins will be <2mm in places across a 9000mm diameter.

The ring stack that is outside at the front of the tent is the same section that was outside at the back of the tent.

A bulkhead is now on a jig/stand outside the back of the tent.
