Building 3' indoor

[tjcezar]

I am building a 3' x 12' halfpipe for my sons (2 & 4yr old) in our barn. Wall to wall I have 23' 8" for length. I am looking for the most practical transition dimension for them. I am going to need approx. 3' platforms so what would you suggest for transition and flat bottom measurements?

any other advice is appreciated too

Hey tjcezar, sorry for the late reply! I'm not sure you have the length for a halfpipe 3' tall with 3' platforms on both sides, check out the ramp calculator at http://www.xtremeskater.com/ramp-plans/ramp-tool/, if you use the defaults ( 6' 10" transition radius, 8' flat bottom ) then input ramp-height = 41.5" ( 3' transition-height + 5.5" flatbottom ) and platform-length = 36", the ramp is 26.36 feet. I've no experience but I'd guess that with young kids you want a less steep transition, which makes the ramp even longer. I would recommend reducing the height a little and / or making one of the platforms shorter.
