(57) A jig for making fence and other framed wooden panels has two lower portions in which
the panel components (B,T,L and S) are laid up horizontally, and a common upper portion
up against which each lower portion is brought in alternation for the components to
be firmly located and nailed. A nail gun assembly (8) is traversed over the jig for
this, and nails can be driven according to a pre-set program and/or according to the
slat edges, the overlap between slats being detected by sensing means (64). In the
lower portions of the jig, battens (B1,T1,L1) are located by lugs (27), the slats
(S) are laid across them, and then further battens (B2,T2, L2) are laid on top. These
can be automatically pinched into position as the jig portions are brought together
by engaging pivoting elements (29,43) on the upper portion of the jig.
