ya i think its the more plasticy kind but im not really sure cause there werent any other types. it cost $15 for all that you see on my setup. slides real well when wet, no need for dish soap or snow gel as long as the drop in is legit.
No, I think he drilled through the bottom because in the pic you can't see any holes and he drilled at the ends and that's the only place where you can really tighten the screws on the inside of the pipe.
most of the dropin is made out of my old picnic table so that didnt cost too much. also the rail and jump are built with wood from around my house. i spent $30 on the metal pipes, $15 on the astroturf, $10 on the little wood that i didnt already have and $15 on the green plastic fence, which really isnt necessary but i just used it cause i bought it last summer. so total price $70.
^yo my bad that was completely wrong. those were the measurements for my previous setup. i just went out and checked the whole thing is 27feet. it includes a 10ft rail, 9ft from the back off the drop in to the end of the ramp, and an 8ft transfer from the end of the ramp to the top of the jump.
