???Automag rail milling???

[GriMachine]

Im tring to think up a of way to make a mag rail. Im not really sure as to how its done. I need some help figuring it out. lol what I really need is formula plans. Any good drafters out there or mechanical engineers. How would I mill the part of the rail that the body lays on? Something really helpful would be like a paper drafting picture with mesurements. If you have any ideas let me know. Post me an idea.

Heres a picture of the kind of a rail im thinking of.

P.S. You can skip the part where you tell me I need a milling machine. I already got one.

You're really going to want to start with an AGD rail for tolerance reasons. Otherwise your marker probably won't work when you put it together. There's a reason no one but AGD makes rails.
