The Dowelmax Jig with distance gauge bar

The Dowelmax is a loose tenon dowelling jig manufactured by the O.M.S. Tool company in Canada. The manufacturer claims that the small manufacturing tolerances of 0.026 mm for the aluminium, brass and steel components of the jig ensure accuracy and repeatability, but the precision manufacturing adds to the unit's cost.

The tool allows the placement of five dowels in one pass. A distance gauge bar provided with the jig allows accurate spacing between sets of dowels.

Joint strength

Tests by both the manufacturer, and Wood magazine (in 2007), claim to show that dowel joints made with the Dowelmax are stronger than most other woodworking joints tested. In addition, a 2011 review by Wood Magazine rated Dowelmax as a superior dowel joinery tool, describing Dowelmax as "the best dowelling jig ever made".
