I don't have any plans but c'mon man, the dude just wants to build a rail what the hell is wrong with that? Check articles under resources or search the forums, I know there's some shit like that in there if you look hard enough. On that note, if you happen to find good plans feel free to message me because I'm too lazy to have a good look myself.
