Found a crazy stat about coolant concentrate in an old shop manual

I was cleaning out our shop's back room and found a binder from the 90s with mixing guides. One page said using just 1% more coolant concentrate than needed can cut tool life by up to 15% over a year. I always just eyeballed it before. Started measuring with a refractometer last week and my inserts are already lasting longer. How many of you guys actually check your mix ratio every time?

My old laptop finally gave up last Tuesday. It had all my writing prompts saved in a folder called 'sparks'.

Had to choose between covering for my manager's mistake or letting a client find out, and I picked the first option which led to a whole new mess.

I covered for her by telling the client the project delay was due to 'unforeseen data issues' instead of her missing the deadline, but now they want a full technical report on those fake issues by Friday.

Rant: That one shutter curtain ribbon on a Pentax 67 that just would not cooperate

Had a Pentax 6x7 come in with a shutter capping issue. Figured it was a simple ribbon replacement, maybe an hour. Wrong. The old ribbon adhesive was basically fossilized. Spent three hours just cleaning the channel with solvent and a dental pick. Got the new ribbon in, but the tension was impossible. Too tight and it jammed, too loose and it dragged. My mentor always said to set it by feel, but I must have redone it fifteen times. The whole job took two full days. Is it better to just replace the entire curtain assembly on these when the glue gets that bad, or is the meticulous clean-out still the right call? What's your breaking point?

Pro tip: a cheap thermal camera can find a short in under a minute

Was working on a laptop with a dead short. Spent an hour checking caps. Borrowed a coworker's FLIR One phone attachment. Plugged it in, powered the board for 5 seconds. One tiny capacitor near the RAM slot lit up bright orange. Replaced it, fixed. Has anyone else used one of these for board repair? Worth the $200?

I thought those new composite shims were just a gimmick until a job in Bend

I was working on a big deck rebuild in Bend, Oregon last fall and the lead guy insisted we use these plastic composite shims instead of cedar. I rolled my eyes, thinking they'd crush or slip. We had to level a 16-foot beam that was over an inch out, and after driving in maybe 30 of them with my nail gun, I was shocked. They didn't split, they held the weight without compressing, and the pack said they were weatherproof, which mattered with the rain we get. It totally changed my mind on using old materials just because they're familiar. Has anyone else made the switch and noticed a difference on exterior work?

I was sure my friend's 'freeze your credit card in a block of ice' trick was just silly, but it actually stopped my impulse buys for a full month.

I spent $400 less than usual because the 20-minute thaw time made me rethink every online cart. Anyone else try something they doubted that actually worked?

A lady in my old shop told me she kept her 1987 washer running with a bent paperclip

Honestly, this was back in 2010 when I was just starting out in a small repair shop in Akron. She brought in a Kenmore direct drive for a new lid switch, but the old one was completely gone. While I was getting the part, she told me she'd kept it going for 3 months by jamming a paperclip into the actuator to trick it. Ngl, it was a janky fix but it showed real grit. Makes you think about how people used to just make things work with whatever they had. Anyone else run into a wild customer fix that actually kind of worked?
