Attach the coping and the masonite
For this step, all you need to do is repeat everything you just did. If you read the instructions carefully, you would have been building the second half and the first half at the same time. If you want to use lag bolts again to attach the two halves you can, but it is not necessary. A few screws should be enough because the overlapping plywood will be enough to keep the two halves together.
Finish adding the masonite
Before you begin this step, you will need to attach the coping (metal pipe). Since we have a tutorial on how to do that already, I will not be explaining it again. Click on our How to apply coping Section for full detailed instructions.
The plywood you will be using for this is 3/8" thick which will be held down by ~1 1/2" deck screws. From now on I will be highlighting where the seems are for each sheet in red. When attaching the plywood, make sure to screw into each and every stud along the ramp. And be sure to start screwing from the top and work your way down one stud at a time (this will ensure the plywood fits snugly against the coping).
IMPORTANT: Be sure that your plywood always ends on a stud. The edges of the plywood are the weakest so doing this will prevent sagging. You can either cut your plywood so that it ends on a stud, or you can add another stud where your plywood ends. Also, make sure you only cover half of the stud because you will need to share that stud with the next piece you put on.
*tip: use chalk line to mark on the plywood where your studs are.
*tip: if you find the plywood isn't bending very easily don't worry. If you start at the top then as you go down, the screws will do the bending for you. Just be sure that you started the plywood off straight because you might not notice it right away.
Continue with the first layer
Next, attach the next sheets directly below the ones you just put on. Again, make sure your plywood always begins and ends on a stud.
Sheet the flat bottom
Just like the previous 2 steps, screw plywood onto the flat bottom following the highlighted seems below.
Apply the second layer
Now it is time to apply the second layer. This layer will not be applied to the deck; just the curve, and flat bottom. The seems of this layer should NOT be in the same spot as the seems from the first layer. Also, you should try to have the sheets of this layer also end on a stud (although it is not as important as it was on the first layer). Now, simply continue applying this layer until you meet in the middle.
Apply the masonite
This part is very simple. Just remember that the spacing of the 2x4's should be 8" in order to achieve maximum strength. Next, just attach the two deck supports (3/4 screws in each).
Finish the masonite layer
Now just finish putting your masonite on the flat bottom, as well as on the decks.
Attach the railing (optional)
This is a simple step. Just screw on two 2x6's on the top, and two 2x4's 1' 6" from the deck. If you want, you can use plywood instead to make a wall.
*Tip: If you want, you can use the railing posts as supports for a wall, or funbox/grindbox, etc. since they are very sturdy.

sweet im starting this ramp today!
@Sk8master53: Nice! You should take lots of pictures and send them in! :)
I love this site. How could I make this an 8 ft instead of a 4 ft ramp
nevermind I see the six foot version, my bad
@skaterdad: Ah, ya! Glad you found that. If you have any questions don't hesitate to ask!

whats the height, length and width of this ramp, and thanks for all the plans! :)
it's approx 30'x16'x4'
do you have halfpipe plans that arent as long as 30 feet??
or do you know where i can find some
Well it really depends what you're looking for. If you made the decks on this ramp shorter it would take off a lot of length. Your only other option would be to build a shorter ramp (example 3 feet high instead of 4 feet).
what would i have to take off the supply list to make it shorter?
would it realy cost $1000 for just:
•Three 4'x8' sheet of 3/4" plywood
•Four 4'x8' sheets of 3/8" plywood
•Thirty 8' 2x4's
•two 16" black steel pipes
•A bunch of screws
cause that seems pretty overpriced
or could i change it from 16' wide to 8' and cut the supply list in half? Please login(right side) or Register to leave a comment.
