Dowel Inserts for the Veritas Maker

Each insert comes with a square socket drive and two guide bushings, the nominal size and the 1/16" undersize (except for the 1/4" insert sleeve, as the lower 16th size to this, 3/16", is too weak for this process). The inserts are made of anodized aluminum and the bushings are steel. The same square drive is used for the two sizes of dowel.
