There is an inordinate amount of gluing required to put together an end grain butcher block. I’m about half way through today’s gluing exercise. In the picture are about 15% of the pieces in the top. They are all rotated 90 degrees so that it is easier to grab, glue, rotate, glue, put in place, and then repeat on the next piece. You’ve got to move quickly so that the glue doesn’t dry too much before you reach the last piece in the line. Hopefully they dry pretty straight so that I don’t have to do as much cleanup work in the morning.
