The Soviet Union always went in for the big stuff, and more than
likely there is a giant hexapod cnc machine setting in a Russian
shop looking for a buyer or a job. One Russian/Soviet firm that
I remember was LAPIK. [Lukhovitsy Aviaton Production and Testing
Complex] which [I think] is now part of the RSK MIG company.

No guarantees but try here

Thanks, George, I'll give them a shot.

Looks like an interesting project. Need any help?

Maybe. The team can do the inverse kinematics with their eyes closed,
but might farm out some of the heavy mechanical work as it's a
distraction.
