Help with refurb/polishing of my OZ split wheels...

[JamesB]

Hello, i'm currently refurbing a set of OZ mito's and i'm having a bit of a problem, i'm polishing the lips at the minute and really struggling to remove the pitting on them. In the photos you can see one lip I have pretty much finished, I will polish it a few more times before i'm happy though. With this I took it back with 240 grit wet and dry, worked my way up 400, 600, 800, 1200 then finally polish on a die grinder with a polishing wheel, then by hand to remove any marks made by the grinder. I'm pretty happy with how it came out, you can see by the close up (kind of) that all of the pitting hasn't been removed but i'm happy with it how it is.

The second lip you can see in the pictures has been taken back with 240 grit wet and dry but this is pitted alot worse than the first one, i've used a (dark red) scotchbrite disc on a die grinder to remove some of the pitting in a small area but i'm worried about taking alot of the metal with it, which seems to be the case! Is there any better way of doing this?

Any advise from people who have done this or pictures of before/after of peoples lips would be greatly appreciated!

Oh, this is the state of that polished lip beforehand...quite impressed with how it turned out considering!

Looks like you've got the right idea! My suggestion is to do 240 & 400 grit dry. This allows you to take off a little more metal, but have more control than the disc. Then switch to wet sanding at 600. Also, be sure that every grit is done perpindicular to the last. I also go up to 2000 grit, but that's more for final shine and not pitting.

I cannot wait to see these fitted.

Just keep at it with the sandpaper, if it doesn't go you might have to just accept it. I had to settle for some on the 5 barrels but they weren't made to be polished these were.

Nice James, getting your popeye arm pumping! Like motocaddy said, dry sand up to around 600 and you could also start at a lower grit than 240. I'd go up to 2000 aswell. There's some real good tips in the polishing thread Seandub started, maybe take a look there May aswell tidy up the lip edge too
