What happens here

The presenter introduces a pattern bit for a router, explaining that it allows for copying any shape perfectly. He shows that the bit is essentially a straight bit with a bearing on top. This bearing rides along a template, guiding the cut. He also highlights that the bit will cut an offset equal to the distance between the bearing and the cutting edge, meaning the template needs to be *smaller* than the desired final cut.

Tools and materials

  • DeWalt Plunge Router DeWalt — To hold and operate the pattern router bit
  • Pattern Router Bit — To cut the shape, guided by the template's edge
  • Plywood — To provide the guide shape for the pattern bit's bearing
