Checking ring end gap. I measured bores with digital verniers. Quite a variance.
#1 4.0620" bore top ring 0.018" 2nd 0.025"
#2 4.0685" bore top ring 0.022 2nd 0.021
#3 4.0615" bore. Top ring 0.018" 2nd 0.025"
#4 4.0690" bore. Top ring 0.022" 2nd 0.021"
#5 4.0620" bore. Top ring 0.018" 2nd 0.025"
#6 4.0705"bore. Top ring 0.022" 2nd 0.020"
#7 4.0620"bore. Top ring 0.018" 2nd 0.025"
#8 4.0715" bore. Top ring 0.022" 2nd 0.020"
General spec sheet with rings says .004 X bore for end gap spec for both top and 2nd ring.
Looks like I'm tight?
****EDIT**** Loose actually, correct?
Perfect circle moly 5/64 top ring.
Cast 5/64 2nd ring.
Gaps were placed facing outside of cylinder. Rings were 1 1/8" deep in the hole when I measured.
Gonna remeasure bores again with telescopics.
