I won a Starrett 12” rule on ebay and it was pretty dirty. I gave it an evaporust bath and cleaned it up, but the etch is fairly devoid of any color. Have any of you filled in a ruler etch before? What would you suggest? Paint? India Ink? I figure I can just hit the whole thing and then lightly sand at fine grit to remove the stuff off the face, leaving only the stuff in the etch. Sound reasonable?

I assume it is metal. I have used a thin paint and then scraped GENTLY with a razor to get some fill in. Post some pics when its done.

There are probably as many ways to do this as there are people reading about it.

If it were mine I’d spray it with flat black rattle can paint.
Then immediately wipe it off the high surfaces with lacquer thinner.
May have to try several different materials for the wiping part to get something that cleans the high parts, but leaves the paint in the valleys. Maybe a piece of denim wrapped around a block of wood? Leather? Paper towel? Squeege?

Cold blue, and then face down on some 400 grit.

+1 on the blueing. Next time, if it’s a Starrett it’s probably hardened and you can skip the evaporust and go straight to rubbing with 400 or 600 grit. It will take the bad stuff off and polish the hardened metal underneath without scratching. That also works for non-Starrett rules that are hardened of course – they usually have a big H at the end of the model #.

Great idea Don—but this (from the site you’ve pointed out) may well be a better choice [scroll down to find the black version]

One machine shop I worked in an old guy told me that all they used to do was rub the rule with a crayon to fill in the marks and wipe off the excess. I can see it working but for how long. Just a story from the machine shop.

I’ve read that gunsmiths used to use crayon.

Brian,

Black shoe polish works well on my carpenter squares and it’s fairly water proof. Buff it out lightly so as not to transfer to the wood.
