 In my last couple of shorts I built some early forms of drills, the pump drill, the auger drill, and the brace drill. After making them I was curious which one of them was actually the most effective and best option out of the three. So I got aboard and put them each to the test. First up was the pump drill, but after several attempts I kept finding that once the bit got fully into the wood there was too much friction and it wouldn't spin anymore. So I tried a few different bit shapes that helped reduce the amount of friction, first giving it a flatter tip and then narrowing the entire bit down. However I continued to run into the same issue. So, well pretty clever design, the pump drill feels kind of finicky. Let me know if it has any suggestions on how to actually make it work a little bit better. All that's left then is the auger and the brace drill. Putting it to a time trial they both actually made it through in almost the same amount of time. However I found each required a different technique. The auger seemed to work best with a lot of force and just a few hard turns while the brace seemed to work best with just a light amount of force in spinning it a lot. The auger was a touch faster but the brace was a lot less work. So I think with a few improvements to the bit the brace drill is going to be the hands down winner.
