I love cooking on these things...these pics were just after iI welded them up ....they are a lot more seasoned now.......A lot of people think they are like woks....wrong....these plow discs are many times heavier,come in a multitude of sizes and they are not as concave.....this way way once its hot ...your fully cooked stuff can be slide to the sides to keep warm without sliding back into the center....hard to do that in a wok.
