Because of heavy damage on the threaded brass piece, when we re-assembled 
the system up/down system, we lowered part of the assembly to take advantage of a region 
of less-damaged threads.  This, however, slightly misaligns the nylon 
belts that connect the up/down knob to the actual part that controls the 

Please turn this knob slowly when moving the stage up/down.  If you turn 
it quickly, the nylon belt will be thrown off of the drive pulleys and 
will no longer control the up/down motion of the stage.

Thanks for your continued support,


p.s. We are having 5 new brass pieces machined for us at the Physics 
Machine Shop.  Those will not be available until late next week.  Until 
they are available, we have no alternative to trying to treat this 
system gently.
