The formula for No. 14 cradle roll angle is different from formula for No. 24. Also, cradle angle can be large based on gear set ratio.
For instance, if gear set ratio is 1.25:1 or larger, then cradle angle for gear should be increased 20%. This can exceed largest Cradle roll angle in change gear table (52.8 deg).
Cradle roll angle = 800/(Pitch x Cone Distance) where formula and gear table are found in
"Temporary Operating Instructions for No. 14 Straight Bevel Generator"
I'm troubled by the wording "Temporary..." so I would like to know if there is a revised formula or table for Cradle Roll.
