This is quick video if building DIY playground with slide, two swings, climbing wall, spider wall and rope.
Material and others:First how many pieces and length and thickness of everything you need to get is depending on your own personal project. So this video and notes here is NOT an exact list of material because everybody has different needs, different size of playground etc.Best way is to draw your own idea on paper and go step by step and create a list of material for everything you need to make your project. This way you should be able to build it.
Please Think about that and create something what will fit to your garden and something what you will like.
For example if you want to build a platform on the 4 legs, you know what thickness of wood you can get from your local supplier and according to this you will know how long and thick screws you will need + how many for each connection and so on.
Some of my materials used in my playground:
4 legs posts are 10x10cm = 4x4 inch 4meter long cutted to 3meters long pieces so this will be the final height of the playground.
1meter pieces from cutted legs was used for platform so final size is 120x120cm = 47x47inch
Upper structure reinforcement wood 6x4cm = 2,36x1,57inch
Stair wood 4x12cm = 1,6x4,7inch wooden
Wooden boards for platform and climbing wall and sandbox 1,5cm = 0,59inch of thickness basically something what you can get locally.
(Ashape) support for main beam for swings is from 8x8cm = 3,14x3,14inch
Main beam for swings 12x12cm = 4,7x4,7inch
Handrail for stairs 6x4cm = 2,36x1,57inch
Spider climbing wall main structure 8x8cm = 3,14x3,14inch
Swings are holding 10mm screws = 0,4 inch
50mm = 2inch fixing belts which you can buy in your local hardware shop
Climbing rope 10mm = 0,39inch this could be thicker or totally different type.
Sandbox structure/ bottom structure8x8cm = 3,14x3,14inch + 6x4cm = 2,36x1,57inch
Wood protection: oil for wood which should deeply penetrate wood surface and dry after a few days.
Big wood screws for main structure M8x160mm = 0,3x6,2inch
Smaller screws for M5x100mm = 0,19x3,3inch
Smaller screws for M4x80mm = 0,16x3,14 inch
+ Some small screws what I found in my pile of screws from other projects.
