this instructable will show you how to easily make a perfect quarter pipe with:

4: sheets of 1/4 inch 4 by 8ply wood
6: sheets of 1/2 inch 4 by 8 ply wood
11: 2 by 4s each 5 ft 11 inches long
2: 2 by 4s at least 5 ft long.

if you want to build a 3 ft half pipe use 3 sheets of 1/2in ply wood. by over lapping the curves.

building supplies:

skill saw or carving saw
table saw circular saw or hand saw
200 - 300 2 inch screws.
a hammer might come in handy.

Step 1: drawing the pull in

get 6 1/2 ft of non stretchy string and a pencil

and a 6 ft board and a few screws

screw the 6 ft board into the ply wood so it looks like my picture.

make sure there is an inch of space on the ply wood between the board.

now for the string

go to the top of the board and measure one inch down from the top and but a screw in to it.

now tie your string onto the screw

and on the other end tie a pencil make sure the pencil is perfectly on the bottom of the ply wood as seen in my picture.

now keep the string pulled taught ,the pencil strait up and go up and down a couple times until you get a nice smooth line. that looks like mine.

now if you're going to use coping or not draw a little notch in the top to put your coping into if you're using a 2 inch tube make the notch 1 1/2 inches each way.
<p>The surfacing image looks like it's 4 feet wide and only needs one sheet to cover, but later you say the platform in 6 feet wide. How did you deal with the surfacing width?</p>
how much does this cost
$200 - $300 at the most. it might even be less.
<p>All the 2x4 s and stuff I got from a construction site for free and Im using roofing nails thtat are pretty strong and long. Now I just need the plywood lol Very nice work everybody. @the_burrito_master hey please email me and give some tips! calikendamateamusa@gmail.com</p>
Roughly 250 to 300. it should be on the cheep side in this economy.
how in the world does that cost anywhere near those ammounts? plywoods like $8-$15 a sheet. and that pipe would be like $10. do you live somewhere where supplies are expensive?
<p>just to let you know you can build this for like 100 dollars</p>
There is no way you can build this for $100. Maybe with lumber prices from 30 years ago. A sheet of legit plywood goes for at least $20 a pop. You need at least 6 sheets to make a small decent quarter. Plus you need about 15 2x4's, screws and tools.
Hey I was wondering how you draw the curve for the 3ft pipe
<p>this cost 389 to build I just bought the stuff</p>
In what world?
<p>how much does all this cost</p>
What is the diameter of the coping?
2 inch.
Is there any way to expand the back of the quarter pipe for more standing room? And how do you bend the wood to fit to the quarter pipe? What kind of pluwood did you use?
for a quarterpipe you should only need 2 sides for any width up to 8feet wide. if you want to build anything wider, you will want to cut all the sides at the same time so they are identical or close enough, and build 2 seperate sections. I used to own a skatepark and built many of the ramps. We also used 2 and 3 inch drywall screws to assemble the ramps, nails wiggle loose or back out over time, deck screws usually strip out before they are completely tight.&nbsp; to bend the plywood for the curve without cracking or breaking wet the plywood with water for about an hour to soften it up. if you use 1/4 plywood use 2 layers and layer them perpendicular for added strength
Well spoke, sorry my designs were pretty flawed... what I was aiming to do was add only one sheet of plywood in the center with notches cut out but that would have been too hard to explain and stuff so I decided to do the double layer.
do you really need the piece of plywood in the middle of the ramp for support? it would save tons of money.
I think u do but u could easily get by with one instead of 2 if you cut out some notches in the sheet and fit it into the rest.
This is a good little learner ramp.<br><br>If you're looking for and actual quarter pipe, as in half of a mini ramp or half pipe, I wouldn't use these instructions. <br><br>This ramp is too mellow to really be considered a quarter.<br><br>If you want a quarter, i'd go with something like this quarter i built which is a little steeper.<br>
Your surfacing looks tricky, why not just overlap it more simply than put all those extra cuts in?<br><br>But, Really, nice work.
surfacing the second layer like i did allows you too use less wood on the second layer, and because you're dispersing the bend across a larger area, you can use a thicker sheet of ply for the second layer.
Depending on if it's 8 ft wide. but it looks like I'd make it bumpy.
doesn't make it bumpy at all, i think it actually makes it smoother. This mini ramp we built in my friends backyard was plyed the same way and it's perfect.
That's pretty cool i want one :D tho i suck at skating so i really don't need one.
&nbsp;Im getting stuff at Lows later tonight, then My dad is gonna make me this tomarow
That's epic can I see some pics have you skated it yet?<br />
Looks awesome, maybe i will actually make this instead of sitting on my butt watching TV
how wide is it?
you should put up a picture of you using it so that we know its awesome...
and if you want to make it more secure on each of the planks going across you could drill holes then countersink them so its flush
yeah. you can even use roofing brackets that helps a ton.
nice one.im gonna try this one
I would really appreciate it if you could take pictures of your progress. like in my instructable hen I could add a real picture for each step.
np...but its gonna take some time to get all i need
tell me how it works for you.
did u take pics or is it a 3d program? iof its a program, wich 1?
Program called True space.
i think you should put the railing on the inside of the ramp so that if you hit it hard you dont know iot loose and fallthrough
dud it's totally supported ,and it's bolted in there.
o ok because i was just suggesting
Looks awesome, I have built one of my own a few years back. Maybe I can find some pictures of it, I'll upload them as soon as I find them (if you guys want to see them ofcourse :P )
cool sure I'd like to see them.
here they are:
nicely done!
That's freaking awesome.<br/><br/>My friend has a huge quarter pipe, it's like this, except it doesn't have that landing place, and it's much much steeper.<br/><br/>Awesome job, the images really help, I'll see if I can ever make this.<br/><br/>+5/5 stars.<br/><br/><sub>By the way, do you have any pictures of yours, if you have one?</sub><br/>
hey do u work for the i'ble community? if so can u ask ewilhelm to send out a contest about making ramps rails and more for like sk8 boarding, biking, and scooters, atvs, dirt bikes and anything else. i really want to see an i'ble on how to make a halfpipe... Thanks, Rye2121
No I don't. But you can ask him! www.Instructables.com/member/ewilhelm
no I don't have one yo can be the first to post pictures of your finished model.
