DIY 3ft. Halfpipe

my instructions for this half pipe will be as clear and precise as possible.

please comment if you dont have an account just make one it's awesome!

this is good to refer to.

if your planning on using this on level cement you wont need to use this step.

for on the grass select a somewhat level aria of ground.

plot out a rectangle that is 8 ft wide 20 ft long.

level it all out make some footers out of bricks the bricks should in the ground so the half pipe will also rest on the ground but the bricks help it a ton.

It's very important that it will be level when it's done. and stay level for a long time.

follow the pictures and the notes on the pictures. :) and happy building.

for an eight foot half pipe you need to cut every board 3 ft 11 inches!!

pic 1 in all you need to make 4 of these!

pic 2 do this to each frame

3 you'll end up with 2 of thees.

you build the final large piece in this step.

you can build this part as long as you want but it sa to be 8 ft from side to side.
mine is 4 ft.long ,yours can be 6 or so but I wouldn't go over that.

the cross beams have to be 7ft 9in.

arrange your built stuff like this and ,put a 3 inch screw every red dot alternating in directions.

they might be hard to get in you might want to take off the closest beam to get your drill in there.

the surfacing.


you will need 6 sheets of 1/4 inch ply wood.

and 1 sheet of 1/2 inch ply wood if you are using the 4 ft. flooring witch I think you people with small pocket books should use.

the coping is the grind rails that go in the notches I told you to cut.

Some people use big bolts that will go all the way through the wood and then use nuts and washers to hold them in place. ***recommended***

big wood screws would also work. *Works*

coming soon.... just look at my quarter pipe instructable it has a nice one but it would be wiser to fully enclose it.
