How we gonna hold all these together?

The plan was to hold the lozenges together between 10ft long sides as 10ft is the maximum length allowed in the raft race rules.
Unfortunately, the longest scrap ply we had for the sides of the pontoons was only a couple of inches shy of  7 feet long, so we made a start with what we had (always a problem when you’re trying to build out of scrap…especially when you havn’t actually got all your materials yet!!)

We cut our longest bits of plywood down to 200mm wide strips (to allow for 2 rows of bottles)  and marked the all important holes for the bottle caps to go through.  Then using what seemed to be my bluntest 32mm drill we drilled all the holes.
Then simply putting the ends of the lozenges through one of the sides and quite literally ‘thumping’ the other side on we had the basics of our pontoon. We held it together with some offcuts of batten and repeated the whole thing again.
