I've wanted to make one of these since I saw the Offerman jig on the Fine Woodworking site and John Daugherty made his 3yrs ago. I put it together this past weekend and tried it out on an 20"x11" elm slab I had cut about 2yrs ago. Works like a charm! My Skil 2.24HP router seems to be holding up just fine with the 1.5" bottom cleaning bit I got from Amazon. I have another elm slab just like this one and 2 larger ones. Hope to have enough for 2 side tables eventually. Then I have 6 or so more slabs in the same size range to get to when I can. They are mix of oak, maple and walnut.
