My dad told me to always round up on car maintenance and I thought he was just being paranoid

Blew $60 on a fancy desoldering gun that clogged after two uses

Had to take it apart and clean it with a wire every time, just get a cheap solder sucker and some copper wick instead, anyone else ditch their expensive desoldering tool?

I finally understood why my grandpa insisted on cast iron pipe

Talking to a plumber last week who said modern PVC is fine but he's already seeing 20-year-old joints fail in this clay-heavy soil. Makes me wonder if the old ways really were built for the long haul or if we just got lucky back then.

Lost a $3k contract last week because of a plotter calibration I skipped

I had a big drafting job for a remodel in Portland. Owner wanted clean as-builts before they started demo. I skipped checking my plotter calibration because I was in a hurry. Prints came out 1/8 inch off on every sheet and they fired me on the spot. Has anyone else had a job blow up from something this stupid?

Unpopular opinion: password managers still freak me out a bit

I mean, I've been using one for about 8 months now after my buddy kept pushing me to try it. He showed me how many of my old passwords were reused across like 30 different sites and I honestly felt dumb. But there's still this nagging voice in my head that says what if someone cracks my master password and then they have everything. I know the encryption is supposed to be solid but idk, putting all my eggs in one basket makes me nervous. Has anyone else felt this way and gotten over it or do you still keep some passwords in your head?

The difference between adjusting a relay with an analog meter back in '92 versus using a handheld diagnostic tool today is just wild to me.

I was swapping out an old Otis controller last Tuesday in a building downtown and it hit me that 30 years ago I'd be spending an hour with a screwdriver and a multimeter, now I plug in a tablet and it tells me exactly what's wrong, has anyone else felt like our job got easier but also less satisfying to fix?

Pro tip: That $40 burr grinder I bought on sale is actually useless for espresso

Spent three weeks choking my machine and pulling 60 second shots before my neighbor told me the grind setting is just a range, not a real adjustment, so has anyone else been fooled by those cheap grinders that claim they work for espresso?

Dropped 200 bucks on a LinkedIn lead gen tool that totally flopped

I bought this tool that was supposed to auto-find ideal B2B contacts, but after a month all I got was spam replies and a bunch of wrong emails. Has anyone else had better luck with those scraping tools or are they all hype?

I finally realized how old most elevator doors actually are

Was swapping out a door operator on a 90s Otis model last week and got curious about the door panels themselves. Looked up the serial number and found out they were original from 1978. That's 46 years of people slamming them open and closed every day. The track was worn down almost a quarter inch on one side. Just kind of hit me how long we expect these things to last compared to like a garage door or something. Any of you guys ever find parts way older than you expected in a routine repair?

I finally checked the hardness of my railroad track anvil

I've been using this old railroad track anvil for about 4 years now and always assumed it was fine. Last month I got curious after a buddy kept talking about his new London pattern one, so I looked up the Rockwell hardness specs for regular rail steel. Turns out most railroad track is only around 40-45 HRC, which is actually pretty soft for blacksmithing. I tested mine with a file set and yeah, it's way softer than I thought, probably why some of my punches keep skipping. Anyone else ever bothered to test their track anvil, or am I just overthinking this?
