Jim, Hugh

We installed two of the four fixtures Jim designed on BSC6.  The parts are shown in the first .jpg below.  The second image shows Jim doing the in-situ assembly.  The large disc plate fits over the Support Tube end and rests on the broad face of the Expansion Bellows outside the bolt circle. The last images show detail of the remaining.  The long bar bolts into the round plate and the small block bolts to the slots at the other end of the long bar.  This short bar catches the back side of the Chamber Flange, actually sitting on the bolts.  The long hose clamp holds the bar inward preventing it from slipping off the back side.  By having this assembly on each end of the Support Tube, it is prevented from shifting longitudinally although we don't really expect it to want to do this.  The original Bellows Shield remains in place and the large diameter disk and the long bars provide some additional protection during transport.

We'll finish the other side tomorrow.  Thanks to Zac for the parts clean up.
