I think a lot of the kit is designed by David Ennis, so some of that is new design, the tender is of course Acorn and we have to allow for a design that is, what, 20 years old? Anyway it is generating a lot of interest, which is good.
Andy - you have an order by E-mail from me already!
As you can see with the preceding photo, I took off that little edge at each end of the lower edge curve. I thought that would interfere with the bending. The top edge was made by using folding bars, one of which has a rounded edge. Starting at the top, it was formed a millimetre and a half at a time by gradually feeding it through the bars, and it was quite springy.
I didn't use the etched ends as a guide as I didn't think they were quite right, almost having a 'shoulder', the whole of the top curve is more rounded, comparison below. The divisions were then filed to suit.... Is it me, I never trust anything in a kit to be right!
