Thanks Brian. I'm feeling slightly dejected about the new cracks.

The good news is that the Kamado held up to an intense weekend of BBQ activities (food pron later), WITHOUT showing additional crack propagation other than the ones noticed earlier.


However, some parts of the JB-welds look like they're melting, as a couple of weld pits have shown up. JB Cold Weld is "temperature resistant" only to 500F.


The maximum temperature did briefly exceed 550F (T-gauge limit) as the coals were ashing up, but I brought it back down.


TODAY'S REPAIR PLANS
  1. Clean out the Kamado. Degrease and de-soot.
  2. JB over old welds.
  3. JB new cracks.
  4. Mortar over JB.
  5. Let dry and cure several days before baking out.
