Adding a rollin

[PhisicalHazard]

Hey, do you think there is any way to add a rollin onto an already existant halfpipe? I'd like to have the channel in there, but i'm thinking there's not really any way to do that. If anybody has any sites with plans, or help, it would be apreciated.

thanks

yah, thats what we were thinking about, but we wanted the channel. But we decided to ad an width wise extension to the pipe, about 4 feet wide, and 4' tall.
