What should I do?

from my past exp with t style rails is they get wobbly after a little bit, i prefer to use an x like design when making it because the extra support it provides.

just turn it into a x frame with 2 bars down the middle for extra support, ive built 4 of them so far for friends and all of them seem to be doing well, most of us range from 150-210lbs i think, we sesh them atleast 4-5hrs a week depending if we go to the mountain since its like an hour drive + classes

If i were you and I wanted to make it 10 feet long, I would make it shorter. Anywhere from 1 to 2 feet tall. Just remember, the shorter it is, the more stable it is. It's simple geometry. I would also put some diagonal supports on the legs and feet. So the bottom looks like this:

oops i done fucked up but you get the idea dude hahaa

yea I was thinking of adding those supports a the bottom of the legs hopefully it works

yeah taht works, the x uses less wood if your short on cash :p but its like 1/2 planks :p


both are solid designs though
