Does anyone know where I could get dimensions etc to make my own agility equipment (well OK, not me personally because I'm not that clever!).  What would you suggest for a few basics to start with?  Thanks!

If you look at the KC agility rules & regulations (scroll on to page 23) you will find sizes etc given.
