Designed by renowned woodworker and inventor Peter Parfitt, we're pleased to provide UJK Technology's Parf Guide System Mark II. A highly accurate means of laying out a pattern of 20mm holes in a work surface, this system makes the task both quick and easy. Thanks to the high precision CNC machining used to perfectly position the registration holes along the two Parf sticks and some classic geometry (the Pythagorean theorem, to be specific), the Parf Guide System produces highly accurate hole positions at near CNC accuracy. With an accurate pattern of 20mm holes and a set of our Bench Dogs, you will be able to make the perfect right angle or 45° cuts with your guide rail and track saw.

The design of the Parf Guide System Mark II preserves and guarantees the long-term accuracy of the jig as well as improving its ease of use. It uses two "Parf Sticks" along with a drill guide and a special 3mm drill bit to create rows and columns of holes at perfect right angles.

The accuracy of the Parf Guide System is dependent on the very tight tolerance of the holes in the Parf Sticks. The drill guides locate positively into holes in the Parf Stick. These guides include oilite bushes to guide the 3mm drill bit. This design prevents any possibility of wear or elongation of these vital holes as a result of repeated use. Additional holes in the Parf Sticks offer the possibility of drilling intermediate holes at 32mm or 48mm centers or holes at predetermined angles other than 90°. The Parf Sticks have a metric scale along one edge so that they may have other uses in the workshop.

How It Works

Based on Pythagorean theorem, the Parf Guide System uses the aforementioned Parf Sticks, along with a 3mm drill guide and 3mm drill bit, to create an accurately placed series of holes with the rows at perfect right angles to the columns. Then, the guide block and a special 20mm cutter come into play to produce the final pattern of 20mm holes.

The maximum effective depth of the 20mm cutter is 22mm (7/8"), so your material should be no thicker than 22mm. The system is intended for use on 18mm MFT/3-style material or similar.

The Parf Guide System Mark II includes two Parf Sticks, each 1m long with a series of 3mm holes along the length at 96mm centers; a 3mm drill guide with 3mm drill bit, and three 3mm guide pins. Plus, a guide block and a special 20mm tungsten carbide drill bit with a 3mm center guide.
