Jim uses routers for many tasks.
It would be too troublesome
and time-consuming to be changing bits and precisely adjusting
the cutting depth for each task as it arises, so Jim has
a large number of routers, each carefully set up for a
specific task. This photo shows just a few of Jim's routers, and this page
shows just of few of the special jigs and fixtures Jim
has created to guide routers for various tasks.
This jig guides a router to trim the sides
("ribs") to the correct length after bending.
A rib is mounted and clamped in the jig; then the router
is run across the aluminum plate on each end and cuts the end of
the rib to a precise length.
This fixture holds the assembled sides firmly in place and
guides a router to trim the edge.

Once the body is assembled, its edges have to be very carefully
routed to create a ledge for the binding. Jim has created
several tools to help with this exacting task.
Here you see Jim in action routing the binding ledge. An
articulating arm holds the router in a fork attached to its end.
Jim scavenged the fork from one of his kids'
old bikes! Also visible is a custom-made table for
holding the body in place during the operation.
A close-up of the clamp holding the router
in place in the fork.
One side of the fork is visible. Also visible supporting
the router from the bottom is a metal routing guide Jim made on the Fadal.
The two components of the binding ledge routing guide
are visible here.
Here the guide has been secured to the router; the router
bit is visible protruding through the plate.

bit and the tip of the guide block that sets the
thickness of the ledge.
