NoVa Area Machine Shop
I am looking for a local shop in or around the Woodbridge/Manassas/Tyson Corner/Alexandria area that can inspect and mill a 13b rotor if needed. I have one concern with one of my rotors. One of the corner seal-housing groves might be a little off. They are OEM 2mm and one of the groves does not allow the apex seal to move freely like the other five. I can get the seal in and out of the grove with a little effort. However, there is no way the apex seal springs would be able to move it in/out once the motor is assembled. It feels like I just need 0.008 milled off.

Have you tried manipulating it by hand, and or carefully sanding the area where it's binding?
If I recall correctly the corner seal areas of the Apex Seal slot can be bent/damaged in shipping if the rotors are poorly packaged. I really think that your first step should be getting the feeler gauge out and trying to manipulate that area by hand PRIOR to sending it off to a shop which will charge you (and likely do the same thing). You also run the danger of a non-rotary shop taking TOO MUCH away, which would then leave you sloppy and probably require you to have the whole thing milled out for 3mm seals which is far from ideal. If, in fact, that area has been slightly bent then you'll also have issues with corner seal clearance, so once you correct that you'll need to re-correct the apex seal slot...
Seriously, throw on something interesting on TV, open a coffee/beer, and break out your feeler gauges/apex seal and just work it while watching tv on a Saturday. You'll need to do that anyway when your setting your clearances and assigning individual seals to slots prior to stacking the motor.

Goopy Performance sells (sold?) a kit that has all the little bits you'll need Goopy Performance Rotor Repair Kit (Give them a call, they're super nice, when I bought my kit several years ago they also came with a little corner seal tool. See if they have anything else that isn't shown)
Have you tried sticking a corner seal in there yet to see if there is any binding on that end? Thankfully I've never had a rotor tip get damaged in shipping (sent out the rotors from my two previous build for CNC work), so that means my experience is limited to just setting clearances.
