[Metalcrafters]

We have a gerneral rule of thumb that we machine as many operations in one setup. Anytime you flip a part you will induce error. Fixtures and tooling are great when you take the time to build it but that is a completely different design process.

You should no trouble machining those pockets in one setup with the same advice as the posts above stated.

My biggest piece of advice, square up the vice and the head. We do this multiple times during build season.
