Introduction: Diy 4ft. or 3ft.quarter Pipe Easy

Picture of Diy 4ft. or 3ft.quarter Pipe Easy

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

Picture of 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.

Step 2: Cutting

Picture of Cutting

cuttin time!

cut along your line.

pic 2 now go get two more ply wood pieces that have to be 4 by 8 ft. and position them under each other and screw them together. snugly!

pic 3 now cut along the line of the first one you made.

cut slots that would fit your 2/4s an the slopeing part cut a notch every 8 inches or so that should leave you with about 5 slots maybe 6 on the last one where there isn't enough room to cut it downward you need to cut it horizontal.

if you're making the 3 ft half pipe use picture 5

Step 3: 2 by 4s

Picture of 2 by 4s

ad some 2 by 4s into all the notches.

pic 3 screw them in now.

Step 4: Surfaceing

Picture of Surfaceing

to build the surface do this.

use the 1/4 inch ply wood and use two layers.

the ply wood will be too long make sure you have about 7 inches hanging off the bottom part. so you can cut it off to make it smoother.
2 cut off whatever happens to hang over the notch that you cut out for the coping and if you aren't using coping cut it off where it comes to the top

to get the ply wood to bend easier you may need to lay it on your drive way grass of patio and spray it with a hose the patio or drive way works the best because it locks the water under it and absorbs it.

Step 5: Copeing

Picture of Copeing

to but the copeing you need to drill 4 holes int o the pipe and then drive a screw through it into the board

pic 2 this is a more detailed description

Step 6: The Platform

Picture of The Platform

the platform is 2 ft long and 6 ft wide. but it can vary about an inch or so.

pic 2 get the shape

pic 3 screw it in place

If I am a beginner BMX rider and can't really grind or anything of that sort, would I still need the coping?

mrminicoop (author)jreger2017-09-06

yes you still would need coping. trust me it will be worth it. and once you get better then you will want it.

jreger (author)jreger2016-06-21

Or better put, do I even need the coping or can I just use a wooden edge?

how long did it take u to build

TheFestivemedic (author)2016-09-20

To all the people worried about price, just look up the concrete version, the filling is Just rocks and dirt covered by the metal, the thing that costs the most about would either be the concrete covering it which would be at most 30$ or the wood sides used to shape the fill

Nice and easy steps

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?

cbrown222 (author)2009-03-01

how much does this cost

$200 - $300 at the most. it might even be less.

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!

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?

brandon_fryar (author)2014-11-09

just to let you know you can build this for like 100 dollars

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.

alecdisco (author)2015-01-01

Hey I was wondering how you draw the curve for the 3ft pipe

cindymilette (author)2014-08-06

this cost 389 to build I just bought the stuff

alecdisco (author)cindymilette2015-01-01

In what world?

peopleclothingcompany (author)2014-03-16

how much does all this cost

skaterboy1499 (author)2013-10-19

What is the diameter of the coping?

2 inch.

currios-crafter (author)2013-08-20

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?

sk8ter20art (author)2011-08-16

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.  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.

pizzabloke (author)2011-03-10

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.

carsonwc (author)2011-01-10

This is a good little learner ramp.

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.

This ramp is too mellow to really be considered a quarter.

If you want a quarter, i'd go with something like this quarter i built which is a little steeper.

Your surfacing looks tricky, why not just overlap it more simply than put all those extra cuts in?

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.

huntertanner (author)2010-03-18

 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?

tjdtjd1 (author)2010-02-22

Looks awesome, maybe i will actually make this instead of sitting on my butt watching TV

That Weasel (author)2009-08-30

how wide is it?

jesus jelly (author)2009-08-01

you should put up a picture of you using it so that we know its awesome...

cbrown222 (author)2009-03-01

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.

KeepTheBrain (author)2009-02-18

nice 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.

klingonprins (author)2009-02-05

did u take pics or is it a 3d program? iof its a program, wich 1?

Program called True space.

k3y3l3e3 (author)2009-01-05

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
