My Baby Mac is driving me nuts.  Shafts 7 and 8 are sticking together.  When 7 is raised, it pulls 8 up with it.  The shaft frame appears to catch on the heddle bar.  When I got it, there were big paper clips  holding the lower heddle bar to the shaft frame.  This helps some, but they come unattached and make the problem worse.  Does anyone have a solution for this
