   1.5 engines (+mirror) at NASM for a sense of scale:Better preserved than the Apollo 11 engines… 😉 I would love an injector plate, but so far, I just have flex-line couplers from the F-1

   To think that all that thrust is vectored through relatively small adjustable gimbal bearings at the base of each nozzle assembly. Apparently not that big a deal from an engineering standpoint, but still amazing…~670 gallons of LOX and RP-1 per second/engine > 1.5 million lbf of thrust/engine. Zoiks!

   "The gimbal bearing secures the thrust chamber assembly to the vehicle thrust frame and is mounted on the oxidizer dome. The gimbal is a spherical, universal joint consisting of a socket-type bearing with a bonded Teflon-fiberglass insert which provides a low-friction bearing surface. It permits a maximum pivotal movement of 6 degrees in each direction of both the X and Z axes (roughly analogous to pitch and yaw) to facilitate thrust vector control. The gimbal transmits engine thrust to the vehicle and provides capability for positioning and thrust alignment."
