Glue or screw?

So the fourth one is up. Brian is now being critical over a couple of small gaps where two shelf sections fit together.

What that did was help us with our decision to screw each section to the one next to it. We had always planned to do that, but Brian had thought for a while about just glueing them. Décision made, he was soon on the task.

Job done, now he just needs to work out how he is going to do the fifth and final piece, which extends beyond the cabinet.
