how does this pattern work

YOU ARE CLOSE... :)

You could run it like that and it might be alright.

To me it looks a bit shallow on the pinion depth-
WHY- Look at the sharp line and the heavy depression and dry area where the marking compound was rubbed away on the drive side (concave side) it is a bit higher on the gear face.
Drive side seems that way also in the last 2 photos. The first photo seems better...Is this the start and then you did more turn later and took some more?? Jim

Like I said the first 2 pictures is more where you want the pattern to be and look like the second to are deteriorating to the high side of the gear SO you need to move the pinion up and in the with about .002. YES it seem anal BUT I have to do this and people PAY.

All in All you can run this and you will probably be ok. :) JIm

P.S. Try to load the pinion or vise verse have a rag wedged against the ring gear outer edge pushing down creating resistance and twist the pinion around making more pressure between the teeth when it spins that will get you a more true reading of what the car weight is going to do to the pattern after 3000+ pounds and 300-500 foot lbs of torque hits. lol. Really this will help make make the pattern show better for you.

Wishing you the best on your set-up. Jim
