I really don't relish the thought of drilling 180 holes in the sheets to begin with, let alone having to make a punch and die set and do it all over again. Not for this project anyway.... I'm just too lazy.
I wouldn't mind sacrificing a masonry drill though to do it in one step though.
How do you go about grinding one for metal use Tony?
I think I have some cobalt drill point end mills somewhere, but would hate to destroy one of those in the process.
