I finally gave up on finding a place for a full-sized router table in the
shop, and built it into my table saw. I already had the Rousseau insert so
building the table extension-extension took about an afternoon. Underbase
is 3/4" Baltic Birch plywood with a Oak frame and hardboard top. Two bolts
through each of the saw fence rails and the RH cast extension.

I took a little more time with the fence with the thought of moving it to a
'proper' router table at some point. Again the frame structure is Baltic
Birch ply with MDF face pieces. I set it up so it could be clamped to the
table saw fence; or rotated and clamped to the outboard end of the table.
The second arrangement allows me to use an extension on the table saw miter
gage (or a sled), if needed. The fence can then be drilled or slotted to
install to the 'proper' table.

With the exception of the insert, dust collection fitting and a few pieces
of hardware most of the materials came from stuff laying around the shop. I
was surprised at the effectiveness of the shop vacuum dust collection.
After running a few test pieces I had minimal waste that got through to the
floor and very little on the table top.
