Every time I go to Japan, I go to the local home improvement store and pick up a set or two of micro drill bits....$15-20 for 20 or so bits going from .2mm to 1.6mm in 1mm and .5mm increments. The little ones break easily. Last time my normal store closed, so I'll have to find a new source....
I won a tool at a contest auction, tucked in with a few other items. It's a spring loaded pen looking device, but it has an ultra sharp point instead of a ball pen tip. I used this to make a small pin prick and this helps give the drill bit a starting point.
I use .010" and .020" brass rod most times, bent at close to the right angle before I insert it. You'd be surprised how much strength this gives. Once rigged (if you use a functional rigging method, like monofiliment), the models are surprisingly strong. You don't have to go too deep at all, less than 1/8"
Not to change the direction of the thread.....
