Just downloading a few pics, with a forecast of 42 deg C, its too hot to do much else.
IN the first pic I applied the glue with a caulking gun. Just went to hardware store and bought a water solluble gap filler cartridge for $1.98. Squeezed the gap filler out and washed it out. Put glue in, insert cartridge in gun and away you go.It is also a great way of applying bog for fillets and was a great help when joining the float halves together.
Clamping the tops on with flat sections of wood rather than screwing gave me a very fair top on the beams. Only downside is it took 40 clamps to do it.
