You get huge forces from the leverage arm, and rigidity is always everything.

I suspect you need 4-8x the section sizes you are using and a box section spindle holder.
For the 200 mm endmills in wood at 800 mm D on blank, indicating about 400+200 == 600 mm free length (++) on the spindle ram/holder.
;D
Thats a 12mm Diameter, 200mm long from RicoCNC.com

No way am I going to carve 400mm deep in wood, foam blocks only! Either way as your saying the frame size needs to be made out of some serious section.
