1 girdle Shutter body

2 girdle (new In 2002) bottom lip (new in 2002) shutter interference is about ? * 0.12 = 3.61 vs OD =

3 0.50 (photo) (photo / difference) Need to check this) 0.06 (photo + difference) (photo) girdle (new In 2002) bottom lip (new in 2002) shutter (guess / photo) (difference) OD = (difference) ID = *0.12 = 3.61 vs ID=3.63. So nominal clearance between button and shutter is 0.010”. Dimensions Blue: directly from E-MIT-46 + E-MIT052 green: inferred from difference and/or photo red: uncertain. Need to verify with more photos clearance = 0.13 (difference) 0.10 – 0.12 (photo) snout for L1 lens holder sticks out maybe  interference Proposal: position shutter off-center with respect to turret (using Vespel bushing) to provide additional clearance at L1 ‘snout’

5 turret Vespel SP-3 “L”-bushing shutter girdle L-1 lens to plasma ‘elbow’ Is there value in adding a vertical ‘lip’ to ensure that shutter can’t be pulled away from the turret?
