Drilling jig for do=it=yourself - consists of board with bores, and slotted apertures for displaceable stop section

The jig is used for the formation of bores, for dowelling of timber sections. It consists of a board (1) with bores, acting as guides for the drill. The board also has slotted apertures, in which stop sections (2,3) may be displaced and locked. The stop sections may be adjusted to the size of the work pieces, and the distances of the bores to the outer edges. Alternately, grooves or rails may be used to guide the angled stop sections. The board may have drill bushes to guide the drill. The bushes may be removable, and may have different IDs.
