What about using vinegar on quartz?

Honestly I felt the same way as @the_daniel for a long time. Then a single bad client showed me how wrong I was. They waited almost four years to claim a feature they asked for was broken, and my old contract had no time limit. It wasn't about a real problem, it was a shakedown. That's why a clear cutoff, like two years, isn't about being unfair. It's about stopping someone from holding a vague threat over your head forever.

Ever try just giving the main line a good hard yank? I found that a quick, sharp pull straight down can shock it loose when a side pull doesn't work. It's saved me from setting up a second line more than once.

The high temp resins are the real game changer. We switched to a printed box that locks onto the core with a snap fit, no more fiddling with screws. It survived a full season of production runs without any warping. Just have to make sure your printer settings are dialed in for layer adhesion.

Ever notice how some things just refuse to be rushed?
