Abstract
A milling device for milling grooves into two boards to be joined together at right angles for comb-like wedge joints comprises a right-angled gauge with a supporting plate and a back plate. Both plates of the gauge are provided with slits in a comb-like way, with the slits passing in alignment into one another and being adapted to guide a guiding piece of the milling cutter. The supporting plate is provided at its free edge with projecting aligning fingers which are staggered with respect of the slits. By introducing the aligning fingers into the grooves of the first board, the second board can be exactly aligned for milling the corresponding wedges.
