As is (mostly) tradition on Sunday, I had a bit of a hangover.....(Too many Chaplins and Corks at a friend's BBQ last night, along with some crazy spirits from our Slovak friend!) so what better way to get over it by doing some cooking. In a bucket. With a a battery charger....yeah, you know!
Ambled out to the garage to investigate the calliper soup. I put the properly crusty calliper in yesterday afternoon, turned up the current, closed the door and then went and got drunk! This morning the current was showing as about 1 amp. Usually a good sign as it's done it's thing. Lifted the calliper out and already big chunks of rust are falling off with out me even touching them. A good scrub and it looks like this...
Needs just a little bit more. As the majority is now gone, it shouldn't take much to remove the rest.
Needed to clean up the scrap bit of steel in the bucket as it was properly crusty with rust. Did that and then chucked in a carrier. Now the carrier's again had been wire brushed with the grinder before ha d as they too had been painted silver. Underneath the silver, I think was red powdercoat. Certainly much, much harder than paint and reacted differently to the wire brush, almost melting and smearing before finally getting removed. I got most off, just a couple of corners where I couldn't get. Thought I'd try the electrolysis as it will remove paint as long as you clean back a section to bare metal. Again, some very good results. These haven't had any further work after coming out of the tank.
Again, it will probably benefit from another few hours but the general idea is that I get them as clean as I can leaving the platers very little, if any, blasting work to do before plating.
