agreed..Hey, Dave; there's two schools of thought here on that. One (mine) says it doesn't belong on the TS as it ties up both the fence and the TS. You've just set up the router for a precise operation and you discover that you need to run a ply wood panel through the saw.
The other school can speak for themselves... >
the real issue is needing the TS for cutting materials that is out of the realm of the track saw...
