Time to tap the holes. I like to fasten my taps in a vice grip as illustrated in the second picture. It holds it way tighter than the other way, surprisingly. And a side note, do NOT loose your tap inside the cylinder. It is no fun at all to fish it out. I accidentally lost mine, and I had to fish it out with a magnet and some needle nose pliers.
