Minor Changes For Next Time.
I finally remembered what else I wanted to mention for things I'd do differently. They are mostly regarding the polish.
I used cotton string to hang the razor while the polish dried. Not the worst thing, but I don't know if the etchant would eat that, exposing the pivot hole previously sealed by means of polish around the string. I snipped it & soaked it real good with polish to resist the acid. That worked, but I'll use a polyester string next time.
Speaking of the pivot hole... originally, I had planned to use a micro fastener to plug it, & cover that with resist as well. I figured getting the polish out of the tiny threads would be a PITA, so that was out. Getting the polish itself out of the pivot wasn't effortless, however. Next time: I will either plug it with a bit of the wife's crafting polymer clay, or an appropriately sized piece of dowel rod. (Still cover plug with resist.)
One last thing about the polish. It was quite a task to remove it in the spots that I had put two or three moderate-to-thick coats. Next time: I will use thin, but adequate coats, limit two, of non-glittery/metallic polish. Outside of that, I'll probably still use a different color to ensure there is no accidental voids in the resist.
Ah, one thing I held as a "high priority item" for resist coverage was the edge! "Yaarrh, matey! Fluid dynamics be a fickle mistress!!" Liquids act funny on acute angles, so I made sure to give that several! coats.
Always feels good to remember pertinent information that slipped my mind :idea:.
Now to continue sanding until it's time for a finishing session of etching. Any questions or comments?? Feel free to ask!

Having a Trainee is Fantastic!
Sanding update! I spent roughly 6 hours, off & on, of my shift on Saturday hand sanding the face side. Lucky for us (maybe? :shrug: ), I took progress pics :D.
Time to start...
