Caught a senior programmer at a shop in Toledo using a dry erase marker on his inspection sheet

I was at this job shop in Toledo last month helping a buddy with a tight tolerance run on some aluminum parts. This old guy who programs the Haas machines there wrote his offsets right on the paper with a dry erase marker. Said he's been doing it for 20 years so he can wipe mistakes off fast. It looked stupid at first but then I tried it on my own setup sheet back at my shop. Actually works better than pencil or pen when you're making quick tweaks on the fly. Has anyone else seen weird little hacks like that from the old timers?

So are you saying we should all start carrying dry erase markers now just cause some old timer in Toledo does it? You gotta admit that trick only works if you're making changes at the machine every few minutes and never need to keep a permanent record. In a real production shop with audits or second shift coming in, that wiped off information means somebody else has to re-check everything or worse, scrap parts cause they copied wrong. I've seen too many guys trust their "system" and then blame the machine when a batch goes bad. There's a reason most shops stick with pen or pencil it leaves a trail.

Didn't Mike Rowe talk about something similar on his show once?

Old timers are full of little tricks like that cause they spent decades figuring out what actually works instead of what looks professional. Dry erase on paper is kinda genius when you think about it - you're basically treating the sheet like a whiteboard without needing an actual whiteboard. I've noticed this same pattern everywhere, not just in shops. Like my grandpa always used a butter knife to open paint cans instead of a screwdriver cause he said it spread the pressure better. The best hacks usually look dumb at first glance but they stick around for a reason.
