[quote="doggman"]I noticed in a thread that suggested that the rotor could be resurfaced. My D6-9U MJK mag is giving me a fit and I thought I’d try to salvage what I have before I order new parts.
What’s the recommended procedure for resurfacing that rotor? Thanks, Craig [/quote]
I been wondering too, hate breaking brushes! urs is alot worst than mine.
I've never tried this, but I would make an arbor and grind on the surface grinder in a spin jig.
I have cleaned up Eisemann G and GV rotors on my lathe. I have used very light cuts, and have not been able to take very much off as the metal is not overly thick. Also with the Bakelite being softer than the brass or what ever Bosch used the metal will be a little proud of the bakelite. I have taken care of this with a light sanding with a fine sandpaper on a flat surface. With all of that being said your rotor looks sad.
Thanks
Ken
It is fortunate that Cat parts are readily available, in cases where they are not, a rotor like this could be duplicated from Delrin (Acetal). It may not be cheap but it can be done and should last a lifetime.

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
