Drilling into the steel (13mm holes) was a lot easier than I expected. Especially with one of those cheap 1/2 horse power drill presses from kmart. Admittedly 2hp would have been better. I drilled a 4mm pilot hole and then the 13mm. I kept lubricating with wd40 to keep it cool. It took around 1 minute to drill. I set the drill to its lowest speed. The steel came off in nice little sharp spirals.

Here is the end result (kind of). Coach screws to go in, steel to be painted and of course so is the concrete. The holes down the bottom are for rebar.
