Originally designed by Gary Helfrich over twenty years ago, the Arctos Jig has been refined and improved and is now one of the best jigs on the market. Whether you’re a hobbyist or a professional builder, the Arctos Jig will suit your needs.

A t-slot aluminum extrusion provides an easy way to make jigs usable for different size workpieces as well as adding an adjustable clamping point for jig accessories such as stop blocks and toggle clamps.

Routing T-slots in your jigs lets you make use of track clamps instead. They are designed for today’s assembly tables and guide rails. A model made by Bessey sells for $20 at Home Depot. Also called guide-rail clamps, these have a number of critical advantages over toggles. The four spring loaded ball bearings do a very nice job of fitting the bar to the slot with out any grabbing. It is a very consistent glide for the entire run of the miter slot. Having the threaded holes as well as the through holes will make it easy to mount the bars to my jig. 80/20 provides T-slot aluminum profiles, or bars, that have channels used to connect other bars and parts — for instance, panels, linear bearings or casters. It is a building system anyone can use to create.

Arctos Jigs are dead simple, rock solid jigs designed to be easy to use and built to last.
