The work on the trio of Super Barns has got to the stage where there's a lot happening but not necessarily a huge amount of progress visible at the first glance.
Take the underframes, for example.
In the last few days all three of them have had their bogie mounting points fixed and drilled, the strip to represent the main frame added around the edge, the truss rods bent and fixed in position and a pair of basic battery boxes glued on.
The advantage of batch building is that although there is three times as much work to do it doesn't necessarily take three times as long because you do tend to get into the swing of it and you don't waste as much time hunting through a bundle of packs of styrene strip to find the right size for the bit you're doing.
I will concede, however, that it is probably three times as tedious.
