Dowelmax
From Wikipedia, the free encyclopedia
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 millimetres (0.0010 in) 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.
Independent test
Tests by both the manufacturer,[1] and Wood magazine (in 2007),[2] claim to show that dowel joints made with the Dowelmax are stronger than most other woodworking joints tested. In addition, a 2011 review[3] by Wood magazine rated Dowelmax as a superior dowel joinery tool, describing Dowelmax as "the best dowelling jig ever made".
