I wonder if the best way to shim a burr with three screws is always use one burr under or just behind the three screws. That will lift the burr free of the mount and avoid the "wavy taco" problem. Then finish shimming by adding additional shims under one or more of those three shims.

Got it. I guess I should use aluminum oxide sandpaper for the steel carrier?

So update:

I got some 220 grit aluminum oxide sandpaper and went to work on the carrier. I couldn't tape the burrs together with the chamber burr screwed in, so I removed both burrs , taped them together and placed them in the chamber. I got through two rings of sandpaper and decided to do a marker test.

First, the chamber:





Next, the carrier:





I need to improve the radial alignment, but the alignment took for that is out of stock from Prima. I still plan on measuring the run off with and without the burrs, but the results look much better

For the radial adjustment, just buy a couple of blades steel feeler gauges of Amazon, works like a charm, that's what I used for the radial alignment on my EK43s.

Would they go around the outside of the rotating burrs? And which size would I use?

Inside of the burr, I use three feeler blades, the EK burrs + carrier isn't a very tight fit.

Sorry. I meant do they go in the outer or inner circle of the burr

Inner circle. The feelers are different gauges, pick the one that fits he best.

So I picked up a dial indicator and I'm not sure how to position it to work with the chamber and carrier. Attached is an attempt.



Do I need a different type?
