Regardless of whether or not the machinist comest through on these, the fact that you were willing to take criticism and re-adjust is to be commended.
I think this hobby could use a heck of a lot more people like you who willing to do that.
It's the only way to push the boundaries of accurate replicas.
That said, fingers crossed.
PS, is there any chance these could be done in stainless as opposed to aluminum?
