Hello ihavenofish,
Wow, that is an awesome machine!. I wonder if I could do something similar in a scaled down size. I actually was thinking of doing something mounted from above the ground, and being able to reposition the gantry for larger work. The worktable would need a method of indexing it to the upper assembly and perhaps a system to reposition it accurately in relation to the top. Maybe just an opened side machine similar to the one you posted would allow unlimited access to 3 sides and that would basically double the actual travel lengths? It is definitely something to think about. Thanks for posting the picture and information!
Regards,
