Mr Chuck Miller,
Your ideas are very very simple but fantastic.
Topic- "Make a long thin drill bit for snaking small wires."
I wanted to drill a whole for normal size wire in 4" thick brick wall. I did not have such a long bit. I took an iron rod 12" long & a little thicker than a pencil having spiral threads on it. I made one end of it sharp with grinding stone. On the tip I made spiral lines with haksaw blade. 1st I made a thick hole in the wall with a normal bit used for making holes in wall. then i changed the bit with the rod I made I drilled. The hole came all through the wall.
