THE PLATFORM IS THE PIECE THAT DISTINGUISHES TODAYS RAMPS FROM THE 70’S AND 80’S..THE PLATFORM PROVIDES A FEW SECONDS FOR YOU TO GET YOUR BEARINGS BEFORE YOU CRUISE UP THE OPPOSITE SIDE OF THE HALFPIPE:

OK..THE PLATFORM FOLLOWS THE GRAIN OF THE REST OF THE RAMP, AND THE 2 BY 4’S ARE SCREWED TO IT AGAINST THE GRAIN..LIGHT GREY IS PLYWOOD,  DARK GREY IS 2 BY 4’S WHITE (KINDA)  IS 2 BY 4 FRAMEWORK:

DISREGARD ABOVE MEASUREMENT..THE PLATFORM IS 46 1/2" WIDE..NOT 4 FEET..NOTICE THAT THE RIBS ARE LESS THAN 4 FEET LONG, THEY’RE 43 1/2 INCHES ..YOU NEED A 2 BY 4 FRAME WORK WITHIN THE PLYWOOD FOR EASE OF CONNECTION TO THE TRANSITION SECTIONS . CONNECT THE PLATFORM TO THE LONGBOARDS, THEN SCREW THE PLYWOOD WITH THE #10 2 INCH SCREWS INTO THE PLATFORM FRAME
..THIS NEEDS TO BE 46 1/2" BY 8 FEET WHEN DONE.THE PLYWOOD WILL OVER HANG THE PLATFORM BY 3/4" ON EACH SIDE..THIS WORKS OUT GREAT, AS THE NEXT PLATFORM SECTION HAS A 3/4" INCH OVERHANG, AND THEY BOTH MAKE UP FOR THE 1 1/2" WIDTH OF THE LONGBOARD....YOU MAKE 3 OF THESE..

THOSE 12 FOOT 2 BY 6’S ARE USED TO CONNECT THE FRAMES TOGETHER..MAKE SURE THE FRAMES ARE EXACTLY 4 FEET WIDE (SQUARE) BEFORE ATTACHING THE 2 BY 6’S... IF YOUR’E MAKING THIS PERMANENT, JUST USE LAG BOLTS AND SCREW THE 2 BY 6’S TO THE FRAMES..NOTICE THE NOTCH FOR THE UPPER 2 BY 6. THIS IS NOT NECESSARY, BUT DOES ADD STRENGTH, AND LOOKS MORE PROFESSIONAL. IF YOR’E MAKING THIS MODULAR, YOU
WOULD PLACE THE 2 BY 6’S THE SAME, BUT INSTEAD OF USING LAG BOLTS, USE BRACKETS , BOLTS, AND NUTS.

DRILL 1/2" HOLES IN ALL THE "X" MARKS. THE BOLDED X’S ARE WHERE YOU CONNECT THE PLATFORMS WITH EACH OTHER...KEEP THEM ALLIGNED WITH EACH OTHER, AND BOLT THEM TOGETHER WITH 4 INCH BY 1/2" BOLTS.

THE WHOLE THING IS CONNECTED TOGETHER BY A LONG BOARD ON EACH SIDE OF THE HALFPIPE, AND TWO INSIDE BETWEEN SECTIONS.I WAS ABLE TO FIND 3 24 FOOTERS (12 FOOT WIDE NEEDS 4), SO YOU CAN BOLT IT RIGHT TO THE ENDS OK THIS IS HOW THIS IS DONE:

REMEMBER, YOU HAVE A 2 BY 6 ATTACHED TO THE FRAME..THIS IS WHAT WE CONNECT THE PLATFORM TO, FOR BOTH SECTIONS. CHECK IT IT OUT:

NOTICE THE OVERLAP BETWEEN THE FRAME AND THE LONGBOARD.IT IS 2 1/2".YOU MAY WISH TO USE 2 BY 8'S FOR THE BOTTOM OF THE FRAMES IF YOU WANT MORE OVERLAP..THIS WORKED FINE FOR ME THOUGH. NOTICE THE PLYWOOD DOESN'T TOUCH THE GROUND..EVEN PRESSURE TREATED PLYWOOD WILL DELAMINATE IF CONSTANTLY WET.
