two presentations with info on mechanics

a) A seminar from early 2019 I gave at Los Alamos

b) A very extensive talk by Howard from a workshop at Desy describing mechanics in 2014.

The STSG have the complete CAD model, I believe now in inventor, I have a copy in solidworks that

was the final HFT we got from LBNL, and that STGS incorporated in the STAR archives.
