I have a formula for wire size and for a # 40 (1/2 CP) roller chain sprocket 11T it works out to be
Wire: 0.3125
MOW: 1.800 +0/-.0057
My experience tells me that, with variations in cutters (esp. shaper) it's best to use a short length of new chain to confirm the actual chain fit. Wrap should be completely around, with only a few thousands play at mid wrap.
