Hello,
There was a lot of email traffic regarding the installation of
the four main control system bearings and subsequent 'stiffening' sveeral
years ago. This is vital to good control.
The main stratagem seemed to be that one should take great care
to ensure that all four are in the same plane, accurately parallel and with
the spacing for control rods as specified. Andy was quite clear about the
precautions called for. So if anyone has questions about these bearings,
they should be cleared up before plunging into the installation.
Happy building,
Ferg
