Drill Guide

This is a task specific tool.
The ones from the hardware store couldn't handle this.

I needed to drill perfectly centered 12mm holes through 12 by 12 centimeter Douglas beams, both perpendicular and at a 30 degrees angle.

All this to build a prism shaped Hammock Pergola for our stay-at-home vacation.

It has
- one 12mm drill guide for the hammock eye-bolts
- two 10mm drill guides for the horizontal cross-beams
- two 10mm drill guides for the beam heads
