Problem: I've got to retrofit a new type of valve in a stainless steel sink in a jail. The old buttons that operate the valves will have to be replaced by new ones which require a bigger hole. So, I'll have to make the hole bigger.
The only tool I can think of to do this is a knockout punch & die. However, the info says it's only useful on mild steel and aluminum. So, do I try it anyway? Is there a better way or better tool to use?
