You mentioned that Jim Lipari had given you the formula for calculating gears for a No.6 Cirkut outfit (K/T=NP to film distance) and specifically the constant (438.46") to be used for this outfit.
Do you (or any other members) by any chance have the equivalent Constants for the other Cirkuts and Cirkut outfits?
You also mentioned later in this thread that the (pitch) diameter of the gear head for this outfit is 9 1/16" - again does anyone have this information for the other cameras?
Lastly, you mentioned the gear pitches used for Cirkut gears (48 for the No.5 and No.6 cameras, 32 for all others) and said that the Pressure Angle "isn't as commonly used as it once was". Does anyone know what the correct pressure angle is for these (two sets of) gears?
