Question about the old rule of thumb for concrete curing time

I was reading a trade journal from the 80s and it said the old 'one day per inch of thickness' for curing is way off for modern mixes. It said with today's additives, a 4 inch slab can be ready for light traffic in like 12 hours under good conditions. I always planned jobs around the old rule. Does anyone still follow the inch-per-day thing, or is that totally outdated now?

Finally got that stuck governor in the old bank building to release after three days of trying.

We were about to call for a full replacement, but a bit of heat and a gentle tap with the brass hammer did the trick. Has anyone else had luck with that method on a really old Otis unit?

Vent: A client in Scottsdale offered me $50 to clean their entire 4-bedroom house

They said 'it's just light dusting' when I got there and the place was a biohazard. Has anyone else had a client try to massively lowball you like that?

I was working on a Garmin G1000 system in a King Air last month and a senior tech showed me a trick for checking the ARINC 429 bus with just a multimeter.

Question about those cheap foam sleeping pads

I bought a $15 one from a store in Bend last summer for a quick trip. It was fine for one night, but on day two I woke up with a sore hip and the ground felt way colder. I used it again last week in my backyard just to test it, and the foam had gotten even thinner. Has anyone found a good cheap pad that actually lasts more than a few trips?

My wife asked me why I always sand by hand before staining

We were in my shop yesterday and she saw me working on a maple dresser. She just said, 'That looks so slow, why not use the orbital for that first pass?' I told her it's how I was taught, that hand sanding gives you a better feel for the wood. But then she asked, 'Or is it just a habit you never questioned?' I've been thinking about it all night. Has anyone else had a moment that made them drop an old, time-consuming step?

Spending $40 on a late fee clause in my contract template saved me from chasing a $2k payment for two extra weeks.

I mean, the client paid right before the extra charge kicked in, so maybe it's just me but that small upfront cost feels like it did more than any follow-up email ever has, has anyone else had a specific clause actually work like that?

Question about a new 3D modeling plugin for AutoCAD

I was totally skeptical about this plugin called 'MeshFlow' for creating complex surfaces. A guy in my office kept pushing it for about two months. I finally tried it on a curved facade project last week and the speed difference was insane, like cutting my modeling time in half. It just handles those organic shapes so much smoother than my old method. Has anyone else found a specific tool that completely changed their workflow for the better?

Just flushed $1,200 on a 'bargain' hydraulic pump rebuild kit that failed after two days on the water.

The seals blew out during a critical dig in Mobile Bay, costing me a full day's work and a tow back to the dock, so has anyone found a RELIABLE supplier for the older DredgeTech models?

Just realized after a job in a 100-year-old house in Savannah that using a flexible drill bit extension saved me two hours of crawling in a tight attic.

I was trying to run a wire down a wall that had a fire block, and the extension let me drill at an angle from the floor below without having to cut a huge access hole.
