I removed the TS extension from my saw. I then cut a couple pieces of 3/4 plywood and laminated them together. Then I cut them to fit between my TS fence rails. You will see that the rails on your saw are held away from the saw top by about a half inch or so...correct? Well, cut your router table to fit in the same way. After you have it cut to size clamp or hot glue a couple boards across the router table and rest the ends of the boards on the fence rails. Now you router top is suspended between the fence rails. Now, mark where the mounting holes go through the rails and where they attach to the side of the TS top. Now drill out those holes and attach the router table to the saw table. I used washers and even a large nut as chims between the fence rails and the router table. Install bolts and tighten it up. Use a straight edge and rubber mallet or a board and hammer to align the router table with the TS table.
I actually drilled new holes in my fence rails, farther out from the saw so that the router table would be supported farther out.
It seems complicated the first time you do it but it really is not.
1) laminate your 2 pices of ply.
2) cut to fit between rails and extend as far out as you want them.
3) suspend top between rails.
4) mark holes.
5) drill holes.
6) attach top between rails using long bolts and washers or nuts.
