Yes David, you are probably right, it may have been more economical to import a part from the UK these days with a more favourable exchange rate A$ compared to the British pound than used to prevail. Also the air freight rates seemed to have droped.
However:-
1)Sean had the battery box fabricated before we knew that he intended to replace it rather than repair.
2) He has a great deal of pride in his workmanship and I suspect that he wanted to look back on the finished unit with the satisfaction that it was built to all new standard.
3) In the scale of things, the battery box was a comparatively small additional job.
4) We are keen to see the project finished and manufacturing a new item was probably faster than searching around for a good second hand item.
Taking a cue from you David, can anyone supply a forward fin fairing?
Hopefully that is the last item we will have to source.
