Jim,
The kreg flipstops work nice but aren't quite as solid as the production stop. I have two flipstops because I broke the tab off one when I first designed the fence, I made the fence 1.5 inches thick. Later when I found the production stop wouldn't fit I had to change the design. The fence is still 1.5 inches thick, but I cut a groove to match the kreg track and mounted it down the middle of the thick fence. It worked out ok but won't be as easy to match up if I make another matchig section to make it longer.
As for the norm hutch/bench, I made my top a little different than Norm. Mine is two pieces of 3/4 inch ply glued and screwed together, and that is place on an oak frame on the flat on top of the vertical frame. Then I edged in 2 1/2 inch Oak leaving room to add the 1/4 inch hardboard. Very strong... you could park a truck on it. The deep drawers on the bottom are nice but without the toe kick its not comfortable to work on the bench much. Good place to lay tools and such as I work though.
