For those interested, the values I used to calculate the deflection are as follows:
.75 length of unsupported shaft
26.5 angle of pinon pitch cone
20 degree pressure angle
3/8" 4140 hex shaft
47 lbs radial pinon load under stall
145 in-lbs at pinon under stall
25 and 50 mm pitch diameters (from AM site)

Don't forget mechanical slop, harder to model.
The slip fit in the being multiplied times that length is more appreciable.
Its probably fine, AndyMark knows their stuff... but it looks scary at first glance.
