able to make depth-of-cut adjustments with a
simple drill press-like quill lever.
So … what exactly is Pin Routing?
It’s a simple operation that uses a shop-built
guiding fixture to make exact duplicates of
workpieces, just like they’ve done in cabinet
shops and furniture factories for years.
Here’s how the Pin Routing
process works:
• A particleboard or MDF fixture is made by
cutting grooves in one side, matching the
shape of the pieces you want to make.
• A straight bit is inserted into the router
motor (mounted in the Overarm).
• A tracing pin (same size as the groove in
your fixture – and your bit) is inserted into
the Table Plate. The pin and bit are then
aligned perfectly with one another.
• A workpiece is temporarily screwed to

(or clamped into) the opposite side of the
grooved fixture.
• The fixture is then flipped over (with the
workpiece attached) and its groove dropped
over the tracing pin.
• The router motor is turned on and the bit
lowered into the stock. The groove is traced
over the pin, creating a workpiece that
matches the size and shape of the groove
in your fixture, perfectly.
• The workpiece is removed and replaced with
a new blank ... then the process is repeated,
if desired.
• Once you’ve made a fixture, cut out as many
parts as you like, then set it aside until the
next time you want to make more of the
same item.
