I certainly agree that putting a router in a table saw wing is a last resort. The table in the video could be a good set up for a lot of shops. I've considered building a table with a pair of those fold-up picnic table legs you can get at a hardware store for about $30. Totally portable and pop the router and plate out, hang the fence on a wall, and shove the foled up table against a wall or at the end of a bench.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
