I just got my SLT 12.2 back from pc and i am running into some problems. I had them tape the bb threads after blasting and before coating. They looks fine. I took a chain saw file and scuffed the pc on the faces of the bb shell. I then got both sides threaded in and when the lock ring is fully tightened and on, the spindle is way sloppy and has far too much play in it. It wont sinch up like a typical bb should.

WTF do I do now? I dont see a way around this....and I am confused to why this problem is occurring. I really cant afford to dump any more money into this build.
