Boring (Twisted) Video

Filed under: Drilling,Uncategorized — Stephen Shepherd @ 7:29 pm

When someone asked to see what the Cook – Gedge pattern drill looked like in operation, I thought a video, a modern archival technique.  The bit is after Mr. Phineas Cook’s New Constructed Spiral Auger from 1772.  In America it is called the Gedge pattern

The piece of wood is some fairly green pine.

Stephen, I think I got it right now!


  1. Nice.

    Was it really that noisy, or did the microphone just distort the sound?

  2. Luke,

    It is difficult to tell, there is some kind of distortion and that clicking sound, I don’t know where that came from. It does make a bit of noise when I drilled that piece of pine and this bit does makes more noise than a Jennings and less than a ________ ____ (I can’t say that here).

  3. On The WoodWright’s Shop (PBS), Curtis Buchanan uses a Gedge bit. The episode is online – 2605 Windsor Highchair With Curtis Buchanan, Part 1. The Gedge stuff starts at about 14 minutes.
