For working on the spectrograph off the telescope, we constructed a tan, steel “alignment frame” which allows us to take the spectrograph off the cart and hang it as if it were on the telescope.  We investigated using the NOAO Flex Rig for this purpose (see photo archive), but decided not to use it for a number of reasons.  The MAESTRO alignment frame is modular, and can be disassembled for transport.   

When set up in the Steward Lab initially, weights were placed under the legs, and the black spacer ring was put between the spectrograph and alignment frame:



At the MMT Common building, the weights were not put under the feet, and if you put the black ring in, you will not be able to get the cart out.  So leave off the weights, and the black spacer rings.

More recent pictures show extensions which were placed to allow easier access to the spectrograph. 

We also labled all the joints with letters:
