The high school ceramics class had a pug mill that needed repair. The aluminum housing was cracked and the stainless steel mixing paddles were worn down.
Cleanup
We first had to clean out the old clay
Repair
I brought it to shop night at Rex’s. We fixed the cracked aluminum housing by brazing it with zinc/aluminum brazing rod. We stick welded the paddles and built them up with stainless steel welding rod.
