After many discouraging days in which everything I tried seemed to go wrong, I suddenly noticed that the sides of my stove (cooker) look burned and rusty at the top. So I covered the ugly areas with strips of aluminum, which are held in place with 6 x 1/2 inch sheet metal screws. I had to go to the hardware store for a new hacksaw blade and a 7/32 inch bit, but it was worth it.

How empowering it is to rip through metal by hand!
