Well, I am tired of waiting for the Incra Jig to show up so I followed Brian’s advice to use a mallet so I got out a dead-blow BFH and knocked the jig on the miter back and forth 6-8 times.

This is the best I could get, after breaking fingers and loose-as-a-goose trial & error on scrap. Was running low on 1/4" scrap, so you can see the first 2-3 joints on the right, where I stopped and checked/adjusted fit on the fly. The rest of the joints from that point moving left, are at least “evenly spaced” and just slightly snug.

I assume… this is as good as can be expected?… without breaking fingers off that is…

FWIW, my miter/fence connection has double-backed tape between them, plus the screws. That seems to be helping my “adjustments” stay in place, or at least that is the hope… ;-)
