Elon Musk recently mentioned a Thrust Puck on Twitter, "We’re stripping SN2 to bare minimum to test the thrust puck to dome weld under pressure, first with water, then at cryo."

He also mentioned this: "There’s a puck at the base that takes the engine thrust load. Don’t shuck the puck!"

What exactly is a Thrust Puck?
