Rout Single Pass Half-blind Dovetails

Single pass half-blind joints share the same characteristics as variably spaced half-blind joints with one notable exception, the pins and tails can be routed in a single pass with both boards mounted in the jig at the same time. Single pass dovetails are generally used when production time is critical. Although not as aesthetically pleasing as a variably spaced joint, the joint is equally as strong and jig set up minimal.

1 Make sure the finger assembly is in the Half-blind Tail mode. The pins and tails are routed at the same time in this mode.
2 If the drawer side is 1/2” or less, insert the nylon stop rod in the tail end of the fingers. The rod acts as a limit stop as the pins are routed. Thicker drawer sides do not require the rod.
3 Insert the spacer in the front side stop in the #1 position. The spacer provides the correct offset for the tail board.
4 Clamp the tail board (drawer side) in the front clamp and the pin board (drawer front) in the top clamp.
5 Set the scale to the thickness of the drawer side (tail board). That’s it — There is only one scale setting and only one finger assembly mode for single pass half-blind dovetails.
6 Use the included Leigh e-Bush template guidebush and the included #80-8 dovetail bit. Or, depending on the drawer front thickness, use one of the five Half-blind bits available.
7 Rout in and around all tail sockets to form the pins and tails in one pass.
