My solution was quick and dirty. I literally have a router box, which
is to say I took an appropriately sized cardboard box, reinforced an
area with duct tape to accept the dust port (2.5"), and duct taped the
ugly thing under the wing. I then cut a "door" in the side for access
to the router and made a small hole for the power cord. A $15 router
switch from Rockler completes the picture.
Red Green would be proud, but this works extremely well. I also have
the split hose arrangement for the fence.
My table extension is almost as low-brow. Cutting the T-Slots and miter
slot in the table surface were the first time I'd ever used a router,
so I wanted to gain some experience before designing and building a
more permanent (and more elegant) setup. Every time I use it I refine
the design of the "future" table.
