I'm using the same picture that you are. 
I was planning on a round piece of drill rod. I'd like a tiny spring to keep it away from the cartridge, but this isn't really necessary.
I was going to drill it at a slight angle towards the rim since that seems likely to work best with my hammer. I was just going to flatten a spot on it so that I can put a cross pin that holds it in. This is how the original seems to be done, and it's how the other small rolling blocks seem to be done.
I've done it before on Jaco pistols, and the only difficulty seems to be in getting the pin to contact the rim of the cartridge.
