What i was saying was the saw that Vmanchoppy put a link to has no chanels of any kind they are just indented in table top with dimension markings to set the rip fence to , A sled on a table that small is risky to say the least and long rip cuts without the saw screwed down to a bench would be very dangerious as the saw would want to tip when the weight was all to the out take side of the saw
