I'm shimmed .007 behind the inner race. Are you saying add to that?
Yes. it looks like you were at .010 before so I would try .012 and lets see what it looks like.

.005 added. Backlash is at .0055

Now we are getting somewhere. Now work on opening up that backlash.
Best pattern yet! Try shifting that carrier to get a couple tho more backlash and I bet you’re golden
I pulled apart the carrier to install shims inside the bearings. Suffice it to say, I discovered the shim delta problem. While I thought the bearings were seated, they were not. Without all the details of why, I'm back to starting over. This is a setback, but one that taught me enough to make it worth the lesson learned, which just happens to match my build thread title.
There is nothing bad about admitting your wrong, as my Mother always said, and this won't deter me from succeeding. At least the mystery is solved and I can now move forward with much more confidence. Stay tuned for more and keep the help coming!
On the plus side, my hands are now calibrated to detect less than. 005 backlash!
Education is expensive. I ran way too much preload on a pinion bearing once. Smoked it within 3 miles and cost me a new ring and pinion set, bearing, and most significantly, time. That lesson was expensive, but it’s that experience that is the best teacher.

Glad you figured that out. Start your pinion depth around 57 thou (includes slinger and baffle if they're thin enough...baffles are usually 10 thou).
Take some brakleen and clean your R&P up so you won't be confused by any old pattern marks.
I have done that before too. Couldn't get the pinion bearing out after. I was lucky that it was a toyota axle so I didn't loose the entire axle, just a drop out third member.
Had a little time this evening to re-baseline. Maybe a little more pressure, but the pattern is looking better.

Did you go with koyo or Timken?
My koyo set from revolution has one Korean bearing for the inner pinion which is annoying. The machining is noticeably worse than the koyos.
All Timken!
You are just a tad bit deep. I think you are within 2-3 thou.
When you install the carrier, leave the caps finger tight. Wack the ring gear both sides with a 5 lb. rubber mallet. You'll know if she's fully seated. Also, set your dial indicator on the back side of the ring gear at the lip to measure run-out. A couple thou can change pattern read. If no one has mentioned, pattern check (with some resistance) and check backlash at more than one are on the ring gear.
