does anyone know the transition radius of the start ramp used at Sidonia? I think PC's computer was playing up so not sure if he is around and I have the money and a couple of days and wanted to knock one up....have found a software calculator to draw the plans but need the transition radius; can anyone help.....4ft quarter pipe just not the same!!!! cheers

PC's ramps:
915mm high (3ft) with surface.
800mm wide.
1200mm long platform.
1000mm radius to the top roll over section that joins at 45 degrees incline to a 2100mm radius transition lead out.

There's a shload of info about start ramps here:

nice one mate; the ramp calculator thing spewed out something that you just would never ride down...soooo with the dimensions you gave and pics 22 23 24 I'm off to see a gazeebo builder bloke we know on Monday to get him to draw it out for us. From a flippant comment from the wife this is turning into an obsessive mission I WILL BUILD THE RAMP. But then we can have slalom on the goldy too.
