Status of the G0 Cryostat Shipping Fixture fabrication, 2/18/02
The pictures that follow show the status of the fabrication of the G0 shipping fixture at Dial Machine, Inc in Rockford, Illinois. The purpose of this page is to inform UIUC and JLab personnel of this status. Updates through delivery to UIUC will be forthcoming. As of today, the aluminum sheet had not been delivered. Ryerson has been contacted by Dial, and hopefully the aluminum will be delivered in a couple of days. I also did not get a picture of the hub plates. These may have been at the subcontractor's faciliity, I will check on them. One frame was almost completely welded Monday afternoon, and the second one will be done by Wednesday at the latest. All but a few small pieces are shown here.

The first "big weldment" assembly
The first frame just needs eight full penetration welds to finish the W18X71 beam attachment and then it goes on to final machining. The second picture shows the beginning of a weld prep groove for one of the W18X71 welds made by air-arcing.
The removable leg and feet assemblies
The feet and legs are welded, machined and primed. They just need a little de-burring. The picture on the right shows the angle brackets that connect the hub plates to the center beam, and those that connect the 7 X 7 beams to the big weldments.
The center and counterweight beams
These beams just need priming and they are done.
The 7 X 7 beams
The fourth beam was in the machine while I was there. It should be done by tonight.
The splice plates and aluminum bosses
From right to left on the left photo, the skid holds the removable leg flange splice plates (with the aluminum bosses in the box on top), the counterweight splice plates, the removable leg web splice plates, and the 1.25" thick plates.
The towing beam assemblies
These are ready to go.
