I recently scavenged a broken Ryobi cheap table saw from the curb (somehow the motor had been broken off at the arbor end!) Got a much better fence than the broken plastic one on my cheap import table saw and a decent blade, for free, plus parts like the table below.
Anyway I noticed that this one had these large holes on the wings of the table, as does mine. Do these serve any actual purpose? I thought about maybe it's someplace to clamp a router to make an auxilary router table, but there's nothing under the table to make that work.
