Parf Guide vs TrueGrid: Which Dog hole System is the best?

In this video, I compare the TrueGrid system with the well-known Parf Guide system for creating an accurate 20mm dog hole grid in a workbench top. More info about TrueGrid: [https://www.banggood.com/custlink/K3D... Or visit my site for more Hooked On Wood Products: https://hookedonwood.online/China-Too... The Parf Guide system has been the reference for many years, but with TrueGrid, we took a very different approach. Instead of using long straightedges, TrueGrid uses a fixed template, a stable drill guide, and expanding bench dogs to create a more secure and intuitive workflow.

I compare the workflow, stability, accuracy, flexibility, price, and the final result against a CNC-made reference top. Both systems can create an accurate dog hole pattern, but they use a very different method. The Parf Guide system uses straightedges and a geometric layout method, while TrueGrid uses a fixed acrylic template and a mechanically locked drill guide. This video is especially useful if you are building a new workbench, replacing a workbench top, or looking for a more flexible way to create a precise 20mm dog hole layout.
