yeah, winter olympics. I'm from australia. it's summer here at the moment so it sort of does my head in thinking about cold cold snow. not that there is much snow in winter in austalia anyway.
Winter olympics is made up a lot of aerial movements and snow.
so this instructable adapts winter olympics to an australian back yard in Summer.
It's a........Trampoline Sprinkler .
Unfortunately I only thought about posting this once I had finished the project. However it is a pretty simple concept.
My trampoline is next to the back porch on a concrete slab. We put it there as my city sometimes gets fierce summer storms and a trampoline is ripe for being picked up and blown away. So it's tied to a sturdy post by cargo straps.
The kids love the trampoline, and because it is hot, I thought adding a sprinkler would be a good way for them to cool off.
Sure I could have just thrown a hose + sprinkler over the side of the trampoline net but that would not have involved hammering any nails.
Actually that is what I have been doing for the last 2 years but it means I have to plug in the hose and unwind it, plug in the sprinkler, tie the hose to the side of the trampoline, then there is the packing up because I don't ant to trip over the hose etc etc.
Adding a permanent solution means no more cleaning up. no more tripping over hoses, no more kids hassling me to set it up.
Now the kids just have to turn the tap on for themselves.
It's a win-win situation.
Material is pretty straight forward.-
1 tap double adapter
6 electrical cable flat wire F- clips
4 conduit clips
1 2.4meter (8ft) piece of 2" X 4" pine - cut in to 2 x 90cm (3') + 1 x 60 cm (2') lengths
1 3 (10ft) meter roof baton 1" x 2" hard wood.
Step 3: Construct the Head
attach the sprinkler to the end of the 3 meter beam. I used the flat electrical F cable holders. 6 or so of them around the sprinkler head held it firmly in place. As the beam was a little narrow I attached the sprinkler head to a piece of marine ply.
Step 4: The Body
the roof of my back porch was equal height to the top of the safety net. As my kids heads get that high when they jump I therefore didn't want them to hit their heads on the sprinkler or the beam holding it. So elevated the beam in the middle.
basic the beam has three parts. end - sprinkler head, middle - fulcrum/raising leg, end - other end.
In this photo you can see the sprinkler head and the raising leg.
the raising leg is basically an upside down T. I place a couple of brinks on it for sturdiness (I didn't want to bolt it to the roof because we might move the trampoline soon).
You can see the conduit clamps holding the hose.
the other end is also a T and flat on the roof. This gives the unit stability. as you can see I placed a couple of bricks on top for support.
I ran the hose accross the porch roof and through a gap between it and the house. the hose followed a down pipe to the tap wher I utilised the double adapter.
that's about all there is to it.
kids were pretty happy with the set up.
they usually jump on it for half an hour or more after school.
it becomes their shower and they dry off outside. - burns off energy and saves getting the bathroom messed up.
this project took about an hour to do. and because I had all the bits it cost $0.
if I move the trampoline away from the side of the house then I would probably run a vertical beam up one of the vertical pipes that holds the big ring which the net is secure to. and then run a horizontal beam from the top of that to achieve a similat result as todays project.
