Hi there.

The handle of my bevel gauge restoration came out a treat but I can’t get past the pitting in the steel arm.

I’ve tried grinding away with my 250 water stone but this will thin the metal too much, ditto with 120 paper.

So I’m trying to polish out the surface with wire wool. The surface is lovely and smooth to the touch but marred by the potholes.

The picture is after a while of buffing with plumbers grade wire wool and wd40.

Would a rust removal solution take away the discolouration? If so I can protect with wax so it doesn’t come back.

Any tips??

Many Thanks.

Try a medium wire wheel, even a small one on a drill should get it.

The wire wheel will do it for sure, and you could try a brass wire wheel if you want to remove the least metal possible and reduce the chance of a brushed finish. Evapo-rust also does tend to take out the oxidation like that, even if it’s not red rust. I’m not sure about citric acid or the other methods. Personally I like to have old tools look old, but you have to make sure you get the rust out or you’ll have to do it all over again.

Have your say...
