PU glue foams and fills gaps.
If you don't have suitable clamps it's very easy to make cawls. Saw a
few pieces of wood so they are slightly bow-shaped on one side and long
enough to span the boards you want to glue. Once the boards are
together put them on a flat surface and the curved side of the cawls on
the top. Clamp the ends of the cawls on to the flat surface - this
applies pressure to the central area and then, as the cawls are
tightened, the pressure spreads to the outer edge. If you don't have a
way of clamping the cawls then a simple windlass will do the job.

Foamed PU glue unfortunately has sod all strength. PVA makes a stronger
joint. There's also casein.

I am a great fan of casein. A bit more fiddly, but good.
