58 degrees? That butter was still plotting its escape.

20 minute sets up on me mid-scoop every single time.

Judge Smith in Fresno denied two of my cases in under 15 minutes last month where I had similar evidence and I'd say he was totally wrong both times. Those quick denials usually mean the judge barely looked at the file, not that they found some hidden legal reason, because they often quote boilerplate language about listings without actually addressing the doctor opinions you submitted. The whole "didn't meet the listing" line is a cop out when the real test is whether the combined limitations prevent all work, not just checking boxes on one specific listing.

Working from the center out sounds like it's asking for wrinkles near the walls.

Four years is actually pretty good for a forge that's been worked hard, most cheap shells crack way sooner than that. That pop sound is never good, I've had that happen on two different forges over the years and it always means the metal finally gave out from all the heating and cooling cycles. The refractory patch is a temporary fix at best, you'll want to start looking for a proper replacement shell or a new forge entirely. If you keep welding on it patched up, that crack is just gonna spread like a spiderweb sooner or later.
