Festool Domino Machine Instruction Manual - page 75
With the leg assemblies completed we
can now add the butterfly leaf pivot
mechanism. The photo below shows the
simple components. Two short male slid-
ing dovetail members are drilled to re-
ceive brass hinge pins. The cross mem-
ber that will screw to the underside of the
leaf is end drilled to receive those pins as
well.
In the photo below the mechanism is slid-
ing into place and in the upper right photo
it is mated firmly to the underside of the
leaf, automatically positioning everything!
Screw it down and you have just built
what is so very difficult to do by more
conventional means.
Once you also add the leaf guide
pad assembly, use screws to pin
these dovetails in place and you are
nearly done. Notice how handy the
Festool right angle attachment for
the drill is in getting into the tight re-
cesses of the frame.
