In an attempt to make my single burner 500 "waffle ready" I welded up a grate today. It's removable but since the original grate is tweaked a bit and welding pulled the small rod, the 2 aren't as compatible as they could be. I will need to install 2 small bolts with fender washers to sandwich the 2 together. Not fine tuned yet. I have a tall based waffle iron. It also accepts a 12 inch skillet. Not as nice as one person who favors blue equipment is building however. Doug
