Yesterday, I finished adding dog clamps that did not interfere with the MC1/MC3 cookie cutter.  I also removed the install arms form MC1 in prep for use on MC3.  I started laying out the cables, but have not yet plugged any in - MC3 is being tested now and hogging the shared MC3/MC1 satellite box, so any testing of MC1 will need to wait until the twins are both installed and the cabling is finalized.  The suspension is still clamped and optic caps on.
