It's easy to build a floating platform or walkway with k12 ... 

Provided all materials are at hand you should be able to finish any of the platforms listed below platforms within a day with some help. All the timber, nuts and bolts needed for these projects are listed in assembly drawings. Please note that due to the technology  used in manufacturing the pontoons the dimensions as indicated in the drawings may vary by up to +10mm, so it is advisable to buy timber a little longer than shown in assembly drawings.

The assembly drawings are provided to assist you, however there are many more ways of putting K12 to use. Please also note that the available timber may also vary in dimensions from market to market, so please use common sense if some adjustments are called for.

You will need the following tools:
power screwdriver
4mm and 10mm drill
measuring tape
