Herb, I was referring to your setup, which I had planned to copy unashamedly, but then decided to go the TS + SMS route instead. I found the dust problem to be worse on crosscut than rip (where your scheme would have been the answer), but even with the vacuum attached, the rip position spewed dust everywhere.
Have only just unboxed the Bosch Glide saw (have yet to unbox the Bosch TS), but out of the box it is dead-on at 90 degrees, and has a 13-something inch cut with the 12” blade. Very smooth cut with the premium Bosch blade supplied. When it wears out will consider a Freud blade. Dust collection not wonderful, but miles better than the unmodified RAS.
Incidentally, I opted for the Bosch TS over the (locally) less expensive DeWalt, Makita and Metabo, largely because of Stick’s unreserved recommendation. Since we get the EU models here, the downside is that the arbor is 30mm, and will not take a dado stack or the Freud box joint blade set. The up side is that the outfeed extension and a sliding right cross-cut table are built-in.
I noticed that Bosch had taken some earlier criticisms to heart, e.g. the blade guard on the TS has been improved, and the Glide saw has a double laser guide.
