Two for the new version of Conker for the base plate, top armour and side armour, two for my dads machine which he is designing and 1 for any spares. It was a lot but I cant see us needing to buy anymore for a long time. Also given that when I got a quote in 2.5mm Titanium for Conker I's base it was £200 on its own I thought it cold be quite a saving... but to late now.
