During the past year or so since we lengthened the trailer chassis, it has become obvious that the join in the chassis was not straight,
and that the rear portion of the chassis sloped down slightly. At the same time, our carriage of heavier items than originally planned has
highlighted the need for additional beam stiffness in the chassis.
The easiest solution was to add a pair of side members to the top of the chassis where the suspension bolts through. In this position the
beams are not going to get in the way of anything, and have the additional advantage of stopping things sliding into the side of the tyres.
An additional plus point was the provision of extra side lashing hooks, something which we had omitted on the original and regretted!.

The beam bolts down through
the chassis at six points, including the suspension mountings.
One of the new (unpainted) beams laid in place on the edge of the trailer decking. The pattern on the ali chequer plate will be
ground off underneath the
beam to allow a flat mounting surface, with a layer of hard rubber between the beam and the plate.
The completed beams after shot-blasting and Zinc-spraying, giving a dull white sheen to the metalwork.
The shot-blasting cleans off any remaining weld flux residue
and gives an excellent surface for painting of powder coating.
One of the cats got into the picture, she thought I was going to make a fuss of her but was disappointed!

The welding marks are still just visible under the Zinc covering.
