When I originally built my out feed table behind my table saw, I (somewhat arbitrarily) set it a 1/4" lower than the table saw surface. I think I was probably concerned with catching the front edge of a board on the table if it was any taller.
Flash forward many months, and that 1/4" drop was annoying as can be.... Once my projects progress past needing the table saw for any additional cuts, I often use the table saw and out feed as an extra work surface, so it was frustrating to have two different heights.
So, yesterday, I took a roundover bit and eased the edge of the out feed table that is affixed to the table saw back rail, and re-set the height to within 1/64" lower than the table saw surface. Test cuts found no "board catching".
I think I'll like this a lot better, and was curious to know others' opinions
