I collect and dismantle all manner of electronic stuff for wire. I used to work at an electrical factory in the early nineties and I'm still working through my collection. Fuse wire works well too. Another good source is gardening suppliers. The wire they use to 'train' bonsai plants is very good and comes in many gauges.
The twist drill is an indispensable tool on my bench. It allows total control of the bit, so if needed, one can drill holes at a half turn at a time. A motor tool keeps spinning even after you switch off the power. Just one of the beautiful jeweller's tools I inherited from my father.
