The table is currently occupied by a large holding jig I don't want to move without first installing some keys on the ends of it to re-align it with the table when I put it back on later. I wouldn't trust the jigs top plane for absolute square and flat as its been a year since I made it. It was machined flat, to that toy mills version of flat then, but that 2" thick block of white ash has now had another year to dry since. It was 10+ years out of the weather seasoned then & should be fairly stable. I should reflatten the area where the boards get clamped to it, with a fresh 2 flute upspiral SC mill, taking off perhaps 10 thou. But this error looks like 5 thou or so just in the 0.760" thickness of the board, so a jig level error would have to be truly huge to make that big a difference. That, OTOH, would be easily detected later this week when those point cutting roundover bits get here. Thanks Ken.
