Ugh. Hand sanding :rolleyes:. And with a first draft, less ergonomic version of the w&d paper dispensing sanding gun thingy linked to in the workshop sticky :banghead:.

While my trainee tried to...

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...

When I first read this about dental picks, the two-ended picks "for small parts" that I frequently see in the hardware section in sets of about four popped into my head. Upon research of dental...

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...

I will now try to detail my mistakes, and what I'd do differently.

First & foremost: I left it to etch for too long. Most of the sources I read on this particular method & mix for etching...

So here is the rough recipe of what I did.

3 parts hydrogen peroxide poured into milk jug, followed by 1 part muriatic acid.

The razor was allowed to hang in the etchant for 45 minutes.

I forgot to post pics of my efforts to contain possible hazards... (i.e.: to at least slow down leakage of corrosive gas.)

There was some "undercutting" of the resist. Something I was aware of being a possibility. Again, more on that tomorrow...

Busy day. Pics now, breakdown tomorrow (later today) when I've got a trainee doing all my work :y:y:y.

Junk metal swept up off the floor at work. "Testing..."

Next up: the rig I've cobbled together to do my etching in! Its features include automated agitation of the mixture, containment of the fumes, and means to carry away & exhaust the fumes out of the...

So, by this point in the project, the blade is more or less prepped to begin the etching process. This seems like a good opportunity to share where I sourced some of my info from.

These are not my...

The 60x I was referring to is the one I inspect my edges with. The 5x "eye socket" type I used for this task was basically the first thing I saw under $10 and at least 5x. I spent less than a day of...

Having already completed it, but needing to fix a spot or three, I applied a thin coat of another color of polish. I didn't have the first one with me at the time, but the different color helped to...

Time to show what was, thus far, the most arduous & tedious part of this restore. I coated the blade with nail polish to use as a resist against the acid, and allowed it to dry for at least a day. I...

Up till this point, most of everything that I've done to the razor is fairly common here at SRP. Even the Evaporust has some first hand users here. The next stage of this restore, AFAIK, is virtually...

As I type this, I am in the middle of a 12hr shift at work in the bakery. I get easy stuff on Saturdays :y! Since I have some spare time, but not the ability to work on my ERN at its current stage...

After many, many, MANY hours of hand sanding, mostly during idle time at work. I kept stepping down in grit until it seemed like there was even somewhat noticeable progress.

220 cheapo w&d from...

Light cleaning, and high grit sanding off some rust didn't produce much progress. I also wanted to at least attempt to neutralize the rust/corrosion of pitting. So next, I played with Evaporust quite...

This thread is to chronicle the journey I have embarked upon to restore an ERN, the very first vintage razor I picked up. Trying to resist my usually long winded posts (forum published...
