Reply To: Twisted worktop?

Roberto, I checked for twist also and planed the underside until it was free of twist. I believe the meeting faces between the apron and the side edge of the benchtop were not square. I neglected to check before glue-up and it’s too late now!

Fortunately the gap underneath wasn’t too huge. The shim was only needed on one leg frame. First, I did plane the tops of the leg frames (the bearers) and got them level with each other. They were both a bit twisty. If you do that, make sure your screws are well below the surface.

I apologize to the OP for completely hijacking your discussion thread. We had the same problem with the worktop at the same time.
