    - a centre rail will add very little for structural rigidity to the box - you need triangulation!!!!! Tieing the box to the tub will help in its rigidity when static but as the draw bar IS going to flex it will actually put more load on the box and may lead to failure?

    - the issue is going to come back to the draw bar a static load of 350kg is nadda compared to a 749kg trailer flexing on three sections of 50SHS bouncing down the road. To test this flexing, remove the front box, fill the tub with a few hundred kg then get someone to tow the trailer whilst you drive alongside the trailer (somewhere safe and preferable mildly uneven road surface) You will be amazed at the amount of flex that will set itself up at the junction between drawbar and box in a dynamic situation.

    Flexing in and of itself is not a bad thing (steel can be used in its elastic range), you can make a trailer too rigid BUT in my experience for offroad trailers its best to control flex in the suspension rather than at the aframe.

    Persoanlly I would traingulate the box making it essentially a self supporting structure attach it to the draw bar with 30mm of clearance to the tub and then run the ladder frame under the SHS. Then after using it for a season and learning - Mk2 will use softer suspension

    Got a Bit more done on the weekend....not happy a the mo, my disco decided to spit its guts and Ive blow a head ....(not to self ..buy a cheaper truck to fix!!!!!... ....anyway after some advise i decided to triangulate the box with a few corner supports and a two more floor and roof supports



    ......got all the alu tread plat cut to size for cladding the box....(after cutting, a few tips, always cut this stuff with a metal aluminum circular or jig saw cutting blade, and when cleaning the edges up use a flapper disk working back wards rather than the normal forward motion on steel)......clad the box today (rivets and silicon) managed to get a hold of a jerry can holder of an old trailer, will mod it to accommodate two Jerrie's as in last few picks the front jerry box....

    Trailers looking good! Bugger about the disco...
    That box, with the cladding should do the job.

    For cutting Al sheet I run the 1mm discs on a 125mm grinder.

    Thanks for the advice mate, ....yhea the cutting was done with a alu cut off circ saw blade...cutting was no worries , it was getting used to cleaning the edges up that took a bit to work out for the first time ...

    Bit more done today...pushing it now ..only one week left to get it painted and rego'd...

    Welded the box into place .....modifyed the jerry can holder to take two in stead of three..like it better this way came up well i thought



    added a few upright stems to take the future stone guard ...the jerry box is bolted in via angel mounts along the drawbar..

    excuse the editing...


    trimmed the doors, cut out the holes for the compression locks and welded the hinges in place...have bolted the doors on the hinges with ss bolts and nilock nuts.....



    has come up well i thought .....the tow ball weight with the box, spare and Jerry's full of water (with the tub on !!) is 60kg, only leaves another 60 to be over the recommended weight for my tow gear....should fine, surprisingly well balanced ....



    removed the tub for cleaning up and painting tomorrow, will do the chassis first and the tube second , the box will be all painted the same color as the tub and chassis ...




    Cheers

    Etch primed the tub today, pics were taken half way through the first coat....





    had a big dent in the tailgate that l wouldn't have got out unless l had taken the the tail gate apart losing the original press rivets, didn't really want to do that so l trimmed a piece of checker tread plate and riited it into the gate, had to tap the bottom edge to a 45 degree angel to roll off the bottom to the edge of the panel in the gate....(thanks Bro).....came up a treat, the license plate light and plate will be attached on the left had side ...
    one down side was that ive gorn to remover the tailgate rubber pinch weld seal and the stuff just fell apart ... >, so will have to replace it.... not happy Jane!!!!,



    cheers
