I would presume at this point that the top would be completely flat. I did not check it with a straight edge though. The plan is to have waterfalls on either side - so it into 3rds (not quite but you get the idea). I noticed that after doing this, the top is very bowed. Very confused at this point as I ran it through the thicknesser. I also noticed that the middle 3rd is more bowed compared to either side.
I just read through all replies quickly and don't think any one mentioned this qwerty.

If you have a made up top that is bowed / cupped ( another name for it )or a wide board that is bowed, its got to be checked that its flat on its bottom before it goes through a thicknesser. Then made flat if it is bowed on its bottom side. The thicknesser has infeed and out feed rollers that makes all flat as it goes in and comes out. A thicknesser takes off some wood and out comes the wood on the other side thinner but still with a bow or cup in it .

What are waterfalls on either side ? Is this the moulding each side of the top , or is the top stepping down in thickness as it gets towards the edge ? Never heard of that . Ive seen waterfall fronts on cabinets .
