Had to choose between binging the new season of Demon Slayer or catching up on the 80s classic Legend of the Galactic Heroes, went with the classic and it's a slow burn.

We ran a 12-inch cutterhead dredge for a month on the Columbia, then swapped to a 10-inch with a different pump curve.

The smaller setup moved 15% more material with less fuel because the pump was matched to the head pressure. I was sure bigger was always better, but the numbers don't lie. Has anyone else seen a big jump from a smaller, better-tuned system?

Cracking the case of the wobbly hydraulic elevator ride

I've been working on this hydraulic elevator from the 80s in a small building for a few months. Each time it got to the bottom, there was a slight shake that never felt right. I checked the oil, the seals, and even the rail guides, but nothing stood out. Last Tuesday, I spotted a tiny drip from the cushion valve that was letting air sneak in. Swapped it out, and now the ride is perfectly smooth. I'm still puzzled why it took me so long to find that leak. Maybe it was too small, or I was focused on other parts. Anyway, it's a small win that makes the job feel worth it, and I'll double-check valves from now on.

Smoke from a garage on my street taught me about EV charger risks

A neighbor messed up his own charger install and it sparked a fire. This reminded me why we always follow code for high-amperage setups. Our whole block was buzzing about it for days.
