The printing press saves the day

I should’ve drawn the press closer to the crack.

But, wait!—the Pilgrims had brought a printing press with them, one of those Gutenberg presses with the big screw used to put big-time pressure on a platen. They dragged the press out of the hold and used the press’ screw to push the beam back into position. They unscrewed the press (lefty-loosey) so it pushed out against the keel and the beam. The Mayflower stayed sea-worthy enough to make a landing off Plymouth Rock. Now when you look at those paintings of Pilgrims setting foot on land you see why they look like they’d just cheated Death.

Inspired by a Currier & Ives print

So the printing press came to America. Happy Thanksgiving!

Here’s a conversation between some engineers/sailors discussing what the actual problem with the Mayflower may have been. The most plausible scenario (to me) is that the main beam cracked, which compromised the standing rigging that held the mast in place (the mast doesn’t rest on the beam, it’s seated—stepped—into a socket down on the keelson at the bottom of the ship. The beam’s job is to keep the rigging taut. The beam is under hundreds of pounds of pressure). Once they got the beam lifted with a screw, they could put timbers under the beam to hold it there. https://www.practicalmachinist.com/vb/antique-machinery-and-history/0t-saving-mayflower-1620-a-382121/
