Action Item List
Tim will supply updated drawings and post on DocDB by this friday
Swager reactivation and rolling spacing check (Zisis/George)

Attendees: Alberta - Jim, Gilbert, Jan, Richard, JLAB - Elke, Elton, Tim, Regina - Zisis, George, Dan, Keith
- Announcements: Tim informed us that three lead vendors have replied and all provide B29-spec lead cut to width in sheets or rolls (~20m length). Vulcan, that supplied lead for the prototype modules is one of the vendors. Elton and George have completed and signed the lead spec document. First article may include lead for the 49th module or at least enough for a 5-10cm build. Turn around time is 20 days.
- Swager Reactivation: It was decided that Regina proceeds with sample builds (of short length) using lead sheets with different spacing of the swager's roller spacing.
- Beam Leveling: Dan's idea and drawing (see above) was discussed. The design seems ok, although there were concerns about the material chosen for the standoffs, their distance along the length, and the fact that loosening the steel beam from the base plate could be a problem.
- Installation: Tim stated that the existing pockets/features on the aluminum base plates should be adequate for lifting the modules of their support beams.
- Latest Drawings: Dan asked Tim to check whether the holes on the base plate are symmetrical along its length, from the center line.
