These are the additional bases required for my Salute game (luckily, my Numidians are already based). There are (I think) 124 of them, each of which needed the edges to be chamfered and fitted with 6-12 magnets. They took me something like 5 weeks of evenings to do, I went through around 60 Xacto blades and a couple of fingers.
The bases at the back are from my FK&P14 range- two of them fit in a 20cm square. The bases at the front are from various other ranges and three fit in a 20cm square. Laid edge to edge, there are 10 metres worth of bases here; the reason for having so many is that both armies will be formed up four units deep across the whole width of the battlefield.
Now I just need to fill them with minis!
