Most rural football pitches visited simply use pieces of wood sunk into the ground to act as posts, sometimes with a piece of string as a crossbar. This causes the following problems:
* The lack of crossbar means you never really know when the ball goes in. This doesn't help when you are playing an important game and there are 200 people arguing on the pitch about how high a crossbar should be
* The wooden posts are rarely secured in the dirt so they are a danger to the younger kids who use them unsupervised
* Termites are widespread in Kenya and they love to eat wood. Consequently the posts don't last long
* You don't get that resounding "ping" when the ball hits the frame of the goal.
So this is how Ben makes some good quality, fairly cheap goalposts.
* Purchase some long lengths of 3" diameter steel water pipe. Water pipe is used because it resists corrosion much better than mild steel pipe. It costs more but should last years longer
* Also purchase some 90o connectors
* Cut the pipe to length. Tap threads on the ends. Paint the posts white.
* Take them to a village. Dig some big holes. 50cm x 50cm squares and 80 cm deep. The square shape of the holes stops the posts twisting
* Screw the posts together and drop them in the holes
* Wedge the posts in place with big stones and make sure they are straight and level
* Make LOADS of concrete
* Pile in about 30 kg per upright. Pack it down and cover the last few inches of the holes with dirt so there's no concrete sticking out to hurt little feet
* Try and stop the kids swinging on the new uprights for at least 8 hours
* Job done. Go and get some chai and chapati
