I have a Vigilant multi-fuel stove with the standard 7.5" legs and after looking for the now non existant short leg kit it was suggested that I cut the current legs to 3". I'm not quite sure what to use to cut the cast legs with. I don't want to break them and I don't own a plasma cutting torch, is there a type of skil or circular saw blade that i can buy that will cut cast iron? Or does someone know where i can get the short leg kits?
