After throwing away the extremely wonky and crappy looking core support crossmember, it was time to make a new one. I got the frame back off its side, put the cab brackets on and dropped the cab in place. With that done, I levelled up the front of the chassis and hung the wings supported on wooden blocks. I then jacked the core support into position and moved it around till it all sat in the right place.
That gave me a position for the bottom of the core support so after lotsof measurements from different points on the frame I took it back out and got some scrap bits to make a guide. After hours of little adjustments followed by re-checking it all over again I was happy with the position. I tacked it all together so I had a reference to work off and had a cup of tea and a think. The ends of the frame were angled outwards (at different angles too), so after even more measurements I set about the 2×4 box section I’d bought to do this. Unfortunately the drop was too steep to do in one piece (I would have had to box the tops and bottoms of the angle) so that one went in the scrap box and plan B was formed. This was to notch out the end for a piece of straight box section to drop down. With it tacked in place, it was time to call it a day. Pretty pleased with it all.
