The Soft Serve Enigma
You can straighten legs, general rule is 10 degrees out is fixable. That said, it is no longer allowed in Canada, any shop caught doing so can have their license revoked. Think about it...bend metal one way, then bend it back, you are severely weakening the strength of the metal. Like said, it can be done, and has been done for a long time, but personally, I wouldn't do it.
