Single Jaw Thermal Test Hardware Progress Molybdenum Shaft has order out to bid: Is long lead (6-8 weeks) and may hold up timely progress So …. Stainless Steel Shaft may be used instead (for this test only) Mandrel fabrication drawing will be completed this week And released to shop soon after Jaw fabrication drawing complete except final dimensions of I.D. Not released to shop yet LARP LHC PHASE II COLL RC1 TESTS - S. Lundgren 06 August 2006 No 6 /22
