Quick Chips: Restoring a sine plate, part 2

In which we look at the results of the WD-40 Rust Remover Soak. We plan the next move for grinding the rolls, and then the plate. We answer a question about how to maintain precision distance between the roles. Also, a cool idea about using CA glue for temporary fixturing.

Going to really like this little series, thanks a lot for sharing.

[@KPNH]

Glad to hear it!

I got to see "Five Digits of Precision" live one time. Great show!
Thanks for bringing us along on the project.

[@KPNH]

I will show the FIVE DIGITS soon. LOL.

[@carltauber2939]

@@KPNH Didn't you play base for Five Digits of Precision?

[@KPNH]

Yes. Yes, I did. Good times. 🤪🎸

I've had Evaporust do the same thing to tool steel. Especially when soaked for a long time.

[@KPNH]

Yeah. I guess if you expect it, it's not so bad. We'll make it all shiny.

I’ve wondered why the steal get’s dark too, but never searched. Your comments inspired me to look it up. Here is what Evapo-rust states:
“The black film is carbon from the steel. Steel is composed of a combination of carbon and iron. In certain instances, steel will darken in color after rust has been removed from the surface of the metal. This is a natural phenomenon that chemists refer to as “carbon migration”. The carbon from the steel moves, or “migrates”, to the outer layer of the metal and settles into the pores. The removal of the rust (iron oxide) reduces the proportion of iron to carbon, leaving a higher concentration of carbon on the outer surface. This heavier layer of carbon could cause a darkening of the metal due to the attributes of the carbon. The darkening does not have an adverse affect on the metal. It merely represents the movement of carbon from the interior of the metal to the exterior of the metal.”

Thanks for looking that up. It's basically what I suspected. Guess it's better than the rust.

[@carltauber2939]

I think the rust removers dissolve the rust, they don't convert it back to iron metal. The rust contained the carbon content of however much steel was converted to rust. That carbon was left on the surface of the de-rusted steel since carbon is not soluble in anything.

[@carltauber2939]

Are the corners radiused, and will you form grind them? How do you dress the wheel for side wheeling?

[@KPNH]

I'll address those in future video!
