Yeah I've done this a couple of times. Use a cutting compound of some description or oil at the very least as the cast iron will melt the outer edges of your drill bit. I've also done this with a 3/8th die grinder burr.

Simple job with the right tools, so simple you'll wonder what all the fuss was about.

The top arms are cast steel, not cast iron.
tip- use a cobalt HSS drill, some cutting oil, and drill slow. :wink:

Or do what I did- see my thread in how-to forum.
