Re: Request help from group

Hello,

FWIW, I have not read all the responses in this thread. Why not use
TWO linear type cylinders? Arranged like "stages" of a rocket. Let
the arm move independant of the rotating table and its base. One
cylinder goes from base to arm, the next goes from arm to table.
Since each will give almost 180° of travel, the 200° need is easily
met. "Wire" them together if it is simply an "end position required"
setup, or use sequential air logic if necessary.

Hope this helps.
