32 mm Shelf Pin Drilling Jig
A 148 mm self-registering drilling jig for the European 32 mm shelf-pin system: five 5.4 mm guide bores on exact 32 mm centres, 13 mm deep for bit alignment, held 37 mm from the panel edge by an 8 mm deep hook fence. Leapfrog it down a cabinet side by dropping a 5 mm shelf pin through the end bore into the last hole you drilled; two 4.5 mm M4 holes let you screw it to a backer board or wooden fence extension.
