hi right now i am in the process of building a 2.5' by 8' halfpipe. I have been using the ramp plans that were provided on the site but they left out one major thing that i need to know.How big of a notch am i supposed to cut out of the top to fit the coping in. The plans dont give you information on this and it just appears in the next step. If anyone has suggestions i'd appreciate it alot.
Thanks, TJ
