Summary of Results

Tom Brown presented the review material and the analysis was presented by Fred Dahlgren.  The analysis indicated the design was conservative with a factor of safety well over 2.  The assembly analysis performed and presented indicated that 4 of the "cans" would interfere with modular coils during assembly.  This was addressed in the design by leaving these four cans off the spool until after machine assembly.  The most controversial part of the design was the Tolerancing of the spool and cans to keep the cost down.  After a long discussion on this topic it was decided that the vendor would be consulted on what was easily achievable and to suggest areas of relaxation of tolerances to keep fabrication costs down.  Four chits were generated on the some details of the drawings and they were dispositioned after the meeting.  This review was considered successful pending resolution of the chits.
