Thanks ill suss that bradproof out and get some,got some seam or stitch sealer in a aero can from camp shop but would mind sealing the whole lot.
The drawbar just cut the old one off carefully through the old welds,if your trailers all square up front and measurements are good both sides back to front shackle mounts pretty easy,set it up so you have 1.8 out the front of course with the bars running all the way to the front of your shackle mounts,get the length sorted then make sure both are identical lengths,have the hitch ends finished except for the bottom plate,both identical and finished except for hitch plate all you need is to set them up measuring off the front of the trailer,even measurements all sides across front of trailer and if ya go to bunnings and grab a digital angle finder,even measurements and even angles across front edge of trailer drawbar should be centred,leave a gap at front (hitch area) for offroad coupling or whatever ya running,tack bars in (noticed you said u had a welder),depending on ya welder or skills maybe get a mobile welder to come around and weld it off for ya,oh yeah cut 6mm plate to join and hitch to sit on and tack it on last,then run prob 50x50 x3mm up the middle to a cross section,this one doesnt need to run to far back under trailer but back pass the front trailer crossmember a bit is better,second crossmember if it has one.
Bit of muckng about but it aint rocket science,prob about $200 in steel then a few bucks for a pro to weld it off if need be,this is what i did,built the whole trailer but got a local pro to pop over and weld off drawbar,cost $100,i suck at explaining stuff in words,see if have a pic of mine somewhere,oh and only weld along length of drawbars,never across them.
Easily done,if i can do it anyone can,only problem is looks like not an option of turning yours upside down or clamping new bars in place,cuppla car jacks either side under timber blocks would do it i think.
