Hatfields and the Teutul's?

TMZ is reporting that Paul Teutul Jr. is starting a competing shop to go head-to-head with his dad's Orange County Choppers shop.

But here's the catch -- Junior has recruited a bunch of disgruntled employees who left his dad's place ... including his brother Mikey Teutul and friends Vinnie DiMartino, Robert "Nub" Collard and Joe Puliafico.
