# '''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. We also need to check the press bed and level it as best as we can.
 +
# '''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.

# '''Review/Update Action Items:'''
 +
#* ''Machining Costs at Alberta:''  Gilbert went over some of the numbers.  400 hours are needed towards the construction of the second press and $1800 is needed for materials (does not include the pneumatic system).  Material cost for jog is $1475 and 90 hours of machining are needed. Just the handling of the 4m+ beams is 150 min per beam (10 handlings).  Gilbert will work on the total estimate and brief description since Elke needs this to move ahead.
 +
#* ''Drawings:'' Gilbert will send drawings of jig and press to Tim.
 +
#* ''Readiness Preparations:'' Richard and Jim reported that the spaces are largely ready with most large pieces of equipment removed and only dusting needed.  The lead 1ft-long calorimeter piece has not been machined yet for inspection by Safety.  Safety also has to inspect the space for glue fumes.  Gilbert will supply a machining schedule to JLab for entry into FastTrack.  Elke mentioned that other updates need to be entered (Construction Manager, student, etc).
 +
#* ''Manpower:'' Jim reported that the Construction Manager description is done and that Suzette is working on the advertisement for that position and this should be ready next week.  The MOU process is also converging.  Jim suggested that we hire students at $16/hour to be competitive; there is a 20% benefit cost and 15% .  Zisis will check the details of the monthly Co-Op salaries in Regina including benefits.  Industrial internships were discussed and the next cycle starts around September at both Edmonton and Regina.
 +
#* ''QA Document:''  Tim clarified that the QA should include ''what'' needs to be done but not the ''how'' (i.e. tooling does not need to be discussed).

# '''Other Business:'''  Zisis asked Jim that he confirms later in the day that February 4 is a suitable date for George and Zisis to visit Edmonton.

Action Item List Oct 15 Alberta Meeting

Minutes

Attendees: Alberta - Jim, Gilbert, Jan, Richard, JLAB - Elke, Elton, Tim, Regina - Zisis, George, Dan, Keith

  1. 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.
  2. 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.
  3. 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. We also need to check the press bed and level it as best as we can.
  4. Installation: Tim stated that the existing pockets/features on the aluminum base plates should be adequate for lifting the modules of their support beams.
  5. Latest Drawings: Dan asked Tim to check whether the holes on the base plate are symmetrical along its length, from the center line.
  6. Review/Update Action Items:
    • Machining Costs at Alberta: Gilbert went over some of the numbers. 400 hours are needed towards the construction of the second press and $1800 is needed for materials (does not include the pneumatic system). Material cost for jog is $1475 and 90 hours of machining are needed. Just the handling of the 4m+ beams is 150 min per beam (10 handlings). Gilbert will work on the total estimate and brief description since Elke needs this to move ahead.
    • Drawings: Gilbert will send drawings of jig and press to Tim.
    • Readiness Preparations: Richard and Jim reported that the spaces are largely ready with most large pieces of equipment removed and only dusting needed. The lead 1ft-long calorimeter piece has not been machined yet for inspection by Safety. Safety also has to inspect the space for glue fumes. Gilbert will supply a machining schedule to JLab for entry into FastTrack. Elke mentioned that other updates need to be entered (Construction Manager, student, etc).
    • Manpower: Jim reported that the Construction Manager description is done and that Suzette is working on the advertisement for that position and this should be ready next week. The MOU process is also converging. Jim suggested that we hire students at $16/hour to be competitive; there is a 20% benefit cost and 15% . Zisis will check the details of the monthly Co-Op salaries in Regina including benefits. Industrial internships were discussed and the next cycle starts around September at both Edmonton and Regina.
    • QA Document: Tim clarified that the QA should include what needs to be done but not the how (i.e. tooling does not need to be discussed).
