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

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.
