Has anyone done this? I have looked into it somewhat and there are kits for it but they are $700 to $2000. I am thinking about putting 3/4" stone or stone dust at the bottom and then cement pillars under the legs, then some sort of metal siding or roofing to keep the sides from caving in. What do you guys think? Any suggestions?
 
i hate how everyone on newschoolers is a fucking asshole. i obviously searched into the subject, i am now seeking more specifics on it as to what materials to use. I am looking for further insight or examples of success/failure.
 
well all you need is a hole and a trampoline. I guess you might want something to maybe support the structure of the hole. some plywood would probably work.
 
it would have to be pressure treated wood which can get pricy so i am looking into mostly metals. i guess no one has done this or has useful advice.
 
if its somewhat temporary (1-3 years) it wouldn't have to be pressure treated wood. main problem is drainage, you're going to want a a few feet of sand as a base
 
my neighbors have one. so fun but make sure you put pads around the corners where the tramp and because landing through that shit blows
 
You need a way to drain the rain water than will inevitably get in the hole. Unless you want to jump above a mosquito infested disease pool.

As for the supports. I would personally line the thing with retaining wall blocks if this is going to be a long term structure. If not... just use some treated plywood and cross braces.
 
The brick idea is really good for the sides to help support it and keep it in place unless the hole is the perfect size for the tramp
 
BRILLIANT!

your way overthinking it. my friend did it.

all you do is dig a (w)hole the the proper depth

you can support the sides with wood if you really need it

then buy some bags of stones at your local hardware store

fill pit with stones

drop in tramp

proceed to bounce
 
Just dig a big ass hole and put the tramp in it. We put bricks under the legs so it doesn't sink in. I guess it depends on your yard but we haven't had any problems with drainage or the walls crumpling. I do feel it doesn't bounce quite as high though (especially with pads over the springs) as the air can't flow freely out under it. It's hard to say for sure though as each tramp has a different bounce anyway.
 
i wasnt getting any advice.. but thanks guys i think im gonna put 2x4s under the legs with gravel/sand at the bottom and ply wood or pallets to hold the walls up. and i'm gonna have a 3" or so gap between the ground and the top of the tramp to help with the air flow. hopefully it'll be done by next week
