Stainless

Trying to do a pair of brake rotors. The holes and slots make it so I can only go in one direction at any given spot (not 90 degrees).

Went 120/220 jitterbug, 320 greasless, then sisal and airways wheels with emery. It's all blotchy. Any recommendation? Shoud I go to white next, or to green?

Re: Stainless

I did a couple of stainless rotor covers a while back they were a pain. I ended up using blue/spiral to finish with and they turned out great. Good luck.

Re: Stainless

i have some s.s. trim pieces in the shop right now that i cant get a 90 degree cut on. i sanded the same as you from 220 to 320 with da, then hand to 600. started out with my 4"electric grinderand 6" spiral wheels with emory. same effect as yours. get good shine but with shadowy spots tried going 180 and it helped out the spots on my parts. dont know where you are working on the discs. if it on the pad surface it should be ok to reverse that way the slot edges will get a cut from both directions. its worth a try

Re: Stainless

Thanks guys - I got the shadows out with a spiral/green but then the scratches came out from the 320...I'll go wet with 600/jitterbug today, then back to the green. Except for the fine scratches, man does that stainless get bright!

Hey pickle, I read elsewhere that excessive rpm's can make those microscratches stand out. I dunno why, but it's something to consider if you can slow your motor down.

Re: Stainless

actually i speed things up and it is working better. i ordered new 10" vented wheels and double stacked them. using the extra fast cut s.s. compound. then second cut is 10" spiral with the green and it is working good. i think i was using a little to much pressure also. now with the faster speed and less pressure it looks like the scratches go away. i will add pics later today.

Re: Stainless
