Sanding diff plates - what grade of wet / dry

[mikeyscott]

Hi,

Giving my Cat SX a bit of an overhaul in the coming week and planning on doing a full diff rebuild and wanted to know what wet and dry to use with the Schumacher Cat SX plates.

800?

start with 600 or 800 then finish with 1200 - 1600 to polish it back up

Ok cool, I will get the grades from B&Q on the way home.

Any particular tips or just follow Lee Martin's guide in the Tamiya section?

I have seen diff plate holding tools, are they worth it? Much More I think

just use a old diff half to hold the diff plate i try to use a sheet of glass to sand on as well, or a mega flat surface

Ok thanks for the tips. mmm tip to find an old diff half or check mine over.

Is it worth trying to sand / revive existing diff plates, or do you only really do the sanding on new plates?
