I just finished glueing up my 3" x 24" x 8' top (after 3 yrs. of waiting), and found that laminating the top into two halves, machine planing them, then glueing them together proved fairly accurate and efficient. I still have some "waves" in the glue-up, but not too bad. If the top still bows during glue-up, I've found wedges jammed between the pipe and glue-up to be really helpful. It was standard practice at the shop I worked in...grab a pile of clamps, a pile of wedges, glue, and go to town.
