if your using liquid nails etc you dont need to wait (i have read that if you glue and then put the 2 bits of wood together then remove and allow to cure for 10 - 15 mins then put back together it will be a stronger bond) but your stand will only have about 60KG on it so it should be ok.
i just glue, drill, and screw in one hit. once you start screwing it all together the stand becomes pretty strong - ive had my biggest setup for about 4 months with no issues, and the 128L has been setup for about 9 months with no issues
