Review on Precision Self Centering Doweling Jig: JoyTube Drilling Guide for Woodworking - Accurate Hole Placement and Centering Locator Tool by Stephen Johnson

Revainrating 1 out of 5

Not self-centering, therefore rather useless

Extremely annoying device due to misalignment. It's not perfectly self-centering, it's off by a few mm. This means you have to flip it when connecting two parallel boards. However, since the jigs are not centered, you cannot use the margin offset as a template. So you'd better be precise with your placement, which is tricky since you can't see if you line up. Absolutely terrible design.

Pros
  • Sturdy design
Cons
  • Discontinued model
