Токарный из рельс - отжиг станины. homemade lathe from rails - annealing warming up the bed

A time-consuming task. I spent almost a month and a half preparing for the annealing process due to time constraints. Current monitoring is only needed to check the integrity of the heating elements and, consequently, the heating process. Each operation must be performed in its proper sequence, otherwise the machine bed can warp. The only thing I needed to do was clean the welds before annealing, but that didn't affect the flooding. It's even cleaner this way, although I did touch the prism in one spot.
