This one from Rod gives us a great extension table for the BT3000. The grooves aid in dust removal. Here's what Rod had to say, "When sawing the grooves (round all the edges first), start by making the first cut dead
center of the table. Move the table to the left and place a ¾” (say) wood strip between
the table and the rip fence. Holding the table steady, remove the strip and carefully slide
the rip fence up to the table. (I found this easiest with the table on the far side of the saw
blade). Make a cut and then swing the table around, end-for-end, and make the second
cut. Repeat this process until you get close to each edge. Equally spaced groves – no
sweat!".
