the minitec company has advised me to use the 90x90 S profiles. n.b. the correct way to mount the minitec posts. material stress will be 7N/mm2 and displacement 200um.
a better way to mount the chamber onto the frame is seen here, with steel taps on the bottom 360 flanges.
the viewports pointing downwards will be useless now. something for next week to think about.
the motor positioning thk company representative will come visiting next week.
