DeWalt’s TrackSaw system makes performing long straight cuts easier on-site, but their router adapter really caught our eye. Just mount your router and it slides right into the 59″ or 102″ tracks from the TrackSaw set — perfect for routing long channels for rails in built-in bookcases.
There’s just one downside: While the adapter’ll set you back just $60, you’ll have to pony up a cool $500 for the least expensive TrackSaw kit (read: the saw with the 59″ track). So if you already have a TrackSaw rig, this would be a cheap way to add some additional (and handy) functionality. If you’re just utilizing your circ saw as a poor man’s table saw — because you’re a cheap-ass like us — you might want to look for a less expensive alternative.
