Hurr hurr. Oh hey, found a problem with one of the acrylic sheets, it seems to be unfinished. Paul, it doesn't match any of the parts drawings exactly - it's closest to "2013 - Parts 05" but doesn't have the B parts, only the T parts.
T1 and T2 are in triples rather than doubles and the T5 parts don't exist other than the 0.75mm deep "channel" cut. T3, T6 and T7 seem fine, but T4 is solid, no central hole.
Just covering all this off in case it was a file problem so you'll know which one it is - otherwise I presume it was the cutter. I'll just mark up and cut the parts myself of course, no drama.
One thing I'm a bit worried about though; I haven't yet dared take the protective film off the main upper hull panels, but quite a few of the sheets have tool marks in the plastic where the router hasn't lifted enough. I hate to say it but I think the cockpit windows might be stuffed!
