I have seen the router tables you can attach to your table saw to save space in the shop and I like the cast iron ones but they are $300 more than what I want to spend. I have a Unisaw with 52" fence. It has the wooden table extension on the side. Has anyone ever built their router table into this section on their saw? I was thinking about doing this and using an attachment for my unifence to make a router fence.

If anyone has done this, can you show me a picture and tell me if there were any problems you ran into?

The only thing I can think of is to make sure I build it facing the right side so I can stand in front of the table instead of reaching across with the workpiece.
