The Em4 is at last complete.

Kate and I fetched the Em4’s articulation mechanism from Sauer Machine in St. Louis yesterday. That’s Warren Sauer, the owner, with Kate, overlooking 2,100 pounds of floor dry used to test the movement. It works beautifully. The box can be moved in two axes; longitudinally (as in downvalley slope) and from side to side.

This morning Jesse and Cara had a good time trying everything out. The skill and quality in machining are unbelievable, and I think I’d agree with Jesse that it’s hard to see how it could have been better done.

No time to rest or celebrate, though. We now have to ready it for transport to Winona State next week. They’ve had a box for some time; we’ll deliver the finished articulation mechanism.
