THE PLANS HERE ARE FOR A TOTALLY "MODULAR" HALFPIPE, WHICH MEANS THIS THING CAN BE TAKEN APART TO THE POINT OF STORING IT IN YOUR GARAGE OR BASEMENT. YOU MAY BE WONDERING "WHY WOULD I WANT TO DO THAT?" THREE REASONS:
 
 

1) Liability...the quickest way to put an end to backyard skating is for some one to sneak onto your property, get hurt on the ramp, and sue you..! it was a big problem in the 70’s and 80’s, and could be again this time around.

2) Weather...even pressure treated plywood will delaminate and warp if left in out the weather; painting extends ramp life but is not a cure all.

3) Neighbors..your dad, mom, whatever..halfpipes can be somewhat of an eyesore, even though they look cool to skaters. the permanence of typical halfpipes has a lot of fathers saying "no way, i’m not having that thing in my backyard" this is where it really shines..and neighbors will be less likely to call the police (halfpipes are very noisy!) if they know the thing will be in view only intermittently.

If you choose to stay with traditional design, you can do that, too..I point out areas in the plans which you can skip. You may not even want to deal with all the modular details, you can get some good ideas (for drawing the curve, for example) and build an entirely different pipe..the modular design is also more work to build, requires some extra skill, and as you might imagine, is not a lot of fun to put together or take apart on a daily (or whatever) basis...although it’s not that bad...if you have friends to help, it actually goes together pretty quick.... : )
 
 
 

"HARDASS" DISCLAIMER! THIS SITE IS FULL OF "CHECK THIS AND CHECK THAT" , LONG EXPLANATIONS, AND IN-DEPTH DIRECTIONS.. YOU NEED TO KNOW NOT ONLY HOW TO BUILD THIS, BUT WHY YOU’RE DOING WHAT YOU’RE DOING.....I’VE BUILT IT MYSELF AND IT REQUIRES A CERTAIN AMOUNT OF SKILL AND A LOT OF WORK!..DEPENDING ON RAMP SIZE AND YOUR LOCATION, PLAN TO SPEND ABOUT 600 TO 1200 DOLLARS BUILDING THIS. THESE PLANS ARE VERY DETAILED, MORE SO THAN YOU’LL FIND ON ANY OTHER SITE..AND FOR GOOD REASON. IF THE TRANSITIONS’ NOT RIGHT, IT WILL NOT BE RIDDEN... AND MAY BE DOWNRIGHT DANGEROUS..SO IF YOU CHOSE TO SKIP STEPS..THAT’S UP TO YOU, BUT AT LEAST READ (YEAH I KNOW IT’S LONG!) THE PLANS THOROUGHLY BEFORE STARTING, AND YOU’LL BE AWARE OF ALL THE "WHAT IFS". ..HALFPIPES, EVEN CORRECTLY CONSTRUCTED ONES, CAN BE DANGEROUS.AUTHOR ASSUMES NO RISK OR LIABILITY ASSOCIATED WITH THE CONSTRUCTION OR USE OF THESE RAMPS.
