Saddle
• Grind by hand due to the late awareness• Not satisfied• Our techs will buff the edges (20 min/part)
~14.0 mm vs. 15.022 mm~0.5 mm unsupported strands during w/c/r

Plan
• 6 middle pole pieces (one LHQ coil) to each vendor
• Verify the thickness• Measure the coating strength as the parts
received and after curing, reaction and thermal cycles. (no impregnation test)
• Vendor selection
