Re: flat bottom length-vs-transition radius and height

a good rule of thumb for mini ramps is twice as much flat as height. the ramps on this site are close enough to four feet high and have 8 ft of flat bottom, and they work pretty well. if you do a lot of lip tricks you want to give yourself enough time to set your feet up and also slow down enough to...

Re: flat bottom length-vs-transition radius and height

For a halfpipe I dont think most people would be happy with anything less than 8' wide. 4' is barely enough to do an axle stall on.

flat bottom length-vs-transition radius and height

Re: mini ramp space problems

go here, http://www.xtremeskater.com/ramptool.php, click on 'mini halfpipe template', to make the length smaller you can decrease the platform length, flat bottom length, ramp height, or decrease the transition radius

Mini ramp help

... we have reduced the overall length to 16' 6", the width to 7' 0" and the height to 2" 6', we have also proportioned the transition radius to suit. We are concerned that the overall length might be a little short to skate. Feedback would be appreciated

Thanks
Jack

4. it is up to you if you want to put 2x4s in the middle of the quarter ...
