Hi Charles,
Yep, thats a big blank. Considered briefly taking a similar project on, then helped my friend transfer ownership for another 40" mirror a few months back. It took 6 of us to move it into a truck by hand and it was in a welded mount with wheels.

As you appreciate first hand, its a lot easier to work massive optics when you are setup for it, we did them at the Perkin Elmer Garden Grove CA shop in the 80's-90's, we owned and worked with Boller and Chivens in Pasadena. Large machines for generating, grinding, an over head crane, large isolate test tunnels, and a roll off roof for star testing.

The Le1m is a good looking instrument!

Looks like a great project, your on the wrong coast for direct help so here is a wish for the best of luck!
