I have no knowledge of what I'm doing so if you think I'm using maths that are to much that's probably true.

The end result is what matters for me. Good looking and good structure that will hold for anything kids can think of.

The slide is part of a indoor play ground, my kids call it "Tower" so when its all done we will probably name it that.

The cost for my slide was around 30 USD

And I'm sorry for some pictures that are unfocused. They looked fine in cam but on computer I now see they are not.

Step 1: Maths

Maths:

2 x wood studs by desired length. Mine is 44x195x2000 (millimetres)
2 x timber battens 22x25x2000 (millimetres)
10 x plank on my size they are 22x70x583 (millimetres)
1 x Oil Cured board 583x2400 (millimetres)

Screws of different sorts
Wood glue
Saw
Nails
Drill and drilling machine or what you fancy
Pen
Something to measure with
Sandpaper
Rasp

And any necessary tool to use to get the job done.

Back support for the slide.

Step 2: Support and Slide Design

I didn't want my slide to be a straight down slide so I added a bump.

I already have a support structure so that part you might have to figure out yourself.

If you have any questions ask. I don't think I can explain what I have done any better than the pictures do.

Step 3: Slide Board Support

I have used the timber battens as support for the planks that will support the slide board.

First I did measure how many I needed to a get a good feeling. Not to far apart so it became a "bumpy" slide because that the planks was to far away.

I decided on my tries to have a space of 140 millimetres between, its a bit bumpy for 79kg. Even if that would be to far away apart for a child I will just add one board on top of this when its worn out so that will be a fix by it self I hope.

Step 4: Cutting the Corners

I don't have any fancy tools so I make do with what I have.

As the corners was way to sharp I needed to make them round. First I found something that I could use, a bowl in my case.
Then I did measure how much I wanted to remove, I decided 80 millimetres.
I cut of the corner roughly with a saw, used the rasp and sandpaper to get it smooth. Use the rasp on the wood not the thumb.
