The corrosion growing on our long-suffering cheese slicer finally ruptured its epoxy coating:
Most of the epoxy remains in good shape, but it’s obviously not the right hammer for this job.
Having recently spotted my tiny sandblaster, I think I can clear off the corrosion and epoxy well enough to try again with good old JB Weld epoxy. It’s not rated for underwater use, so I don’t expect long-term goodness, but it’ll be an interesting comparison.
Bonus: the slicer will start with a uniform gray surface!

Is there a passive oxide you can form before you slather epoxy on it? Maybe that will stop or hamper corrosion.
At my skill level, any oxide I’d create would look more like corrosion than a surface treatment. I sandblasted the thing until it looked better, the JB Weld epoxy is curing even as we speak, and if it lasts another year, that’s OK by me.
Gotta improve the roller, though: the screw threads have been chewing up the aluminum tube pretty badly.
This is going to end up in a cheese slicer milled out of a billet of 316, isn’t it? :-)
Hard anodized for the win! (Did that for a auto-stereo mount after the first stereo went walkabout. IIRC, the metal finishing shop was affordable, but it was in the mid ’80s.)
In gaudy purple, fer shure!
I’m thinking backyard drop forge …
Don’t tease. :-D
Billet Cheeseslicer would be a pretty good name for a band, but I think you should go over it with hardfacing rod just to be sure.
