Your problem is the pivot distance of normal tilt
#106,116,118,122,= 0 [no pivot distance]
There is a conversion which i possess which give you the formulii for any given pivot distance to a zero pivot distance and zero pivot dist. to a given pivot distance .
It can get complex due to a normal radial dist. and radial distance of eccentric of Gleason m/c.
I will look further into this as Hypiods can make a big difference,due to vertical offset.
Cutting Hypiods without m/c vertical offset is very simple to convert between all machines,as long as the pinion blade angles [IB & OB] and diameter is perfect.
I tend to cut GEAR WITH OFFSET as you can use non stadard cutters.
The conversions i have apply ALL methods of cutting spiral bevels even though there maybe a vertical m/c offfset setting, this remains constant on all Gleason m/s.
