I have a brand new set of Zimmerman rotors for a 951 S that are solid. I want to get them slotted. Who can do this and roughly how much would it run to do all four?

Try Paragon, I think they slot them themselves.

edit: shipping costs would be high though. I agree (below) try a local machine shop. I know someone who does his own, but not sure how he does it.

Any machine shop would be able to do it, I would think.

You would think but I kinda want to make sure they slots are even and cut correctly so I would rather have someone who has done it or is doing it as a service complete the job.
I have two machinist that I work with and they are good kids but did not have any idea how to line up the rotors for acurate repetability.

Hey;

Anyone with a mill can do it. A rotary table makes it a lot easier. Make sure they use a ball-end tool. I do my own. Three .125x.040 deep cuts 120 degrees opposed to eachother. Works like a charm.

Do you radiate them straight out from the center or do you run them across the rotor forming a triangle? Or does it matter so long as they are straight? I saw a rotor this weekend that simply had two paralel slots run across the face which struck me as interesting.

That's how Paragon does theirs. Two parallel slots, offset 90 degrees for the flip side.

I've seen others in the shape of a triangle, eliptical, and straight out from the center. Not sure which is best or if it matters.
