    Default How do I improve contrast on a taper scale?

    This is the taper scale from my KO Lee tool and cutter grinder.

    As you can see it is hard to read. What would you do to improve its visibility?

    Perhaps rub over it with a lacquer stick and then wipe off excess on a single sheet of newsprint damp rather than wet with lacquer thinner. The newsprint needs to be stretched on a flat surface so it only wipes the top surface, not the recessed markings. you turn the scale face down onto the newsprint while wiping.

    Yep, got to it first, I think it would work pretty good. Or you could use the little paint bottle that has a needle on the end.

    Black oxide it, then paint the markings white?

    These days?

    Look for an electronic replacement I could adapt.

    Stuff has gone cheaper than time wasted or errors made, long since, can improve USEFUL accuracy and improve throughput of even some rather tired platforms it gets hung onto.

    Last one of that ilk I just laser printed and laminated. If it wears out I'll call up the file and do another one. Life is too short for the level of detailed futzing around needed to do a good refurb job.

    Which I have done back in the day when there was no alternative. But takes ages to get it right-right. Staring at a crap or "well sort of OK" job puts my temper in the danger UXB red zone too fast for comfort!

    One before that couldn't accept a lamination job so I made it from scratch. Rotary table and engraving cutter on the Bridgeport. Do not disturb notice on the door. Got 'er done surprisingly fast. Getting my eye in on the number stamps was possibly slowest part.

    walmart sells kids paint. florescent green mixed 1/2 and 1/2 with glow in the dark paint works wonders. even after using flashlight it glows by itself for quite some time. they sell black paint too

    Sandblast it, then nickel or chrome plate. Blacken the engraved lines with lacquer or carbon black or marker

    Use a white grease pencil to fill in the engraved marks.
