nhbuck1, If the BH in question is a model glued onto an adapter, just heat and loosen the glue and re-glue with it on the adapter straight. I prefer Ferrl-Tite for this instead of an epoxy. If it spin-tests crooked and it's a BH model that is built 1-piece, then check to make sure your shaft is cut straight and that the insert is glued in straight. If all that checks out good, then the BH itself would be the culprit and could be bent or out of straightness. If it's the BH itself (1 piece design, crooked ferrule), then that particular BH will end up in the metal recycle bin. If I ran across more than a couple 1-piece BH's that were manufactured out of straightness, then I'd seriously consider switching brands of BH's!
