The whole assembly is most likely the product of many hours of C.A.D. modelling. If Nikon went as far as defining a loading scenario i.e. what would it take to break it - then the results are only as good as the f.e. mathematical model, boundary conditions etc and the material properties used, which is very difficult with grp due to the random orientation of the fibres. So, as you say, the bottom line is - don't drop 'em.

A look inside - Click here to comment on this image. The box mounts are now built up and waiting for 1.8mm drill to drill out the screw holes - screws and F-FO unit on way from Nikon.

That looks quite spaced out for camera inners. When I changed my D70 low pass filter to IR it was like open heart surgery. I had a photography mate swabbing my brow and standing by with oxygen. Never again. Mind you it was a camera I bought new, so the pressure was on my Thrift Gland not to mess up. lol

99% of the gubbins is crammed in behind and both sides of the mirror box - thankfully it is straightforward to remove the front casing - anything more needs the back and top off and then you start pulling ribbon cables and connectors and I know from my lense fixing escapades that that can lead to issues of broken ribbons which are a sod to fix,

I had to open her up again to add to the stress. Second time it all worked fine. After a few test frames in the back garden, this was a quick trip to Castle Rising for probably my first IR photo....certainly the oldest surviving!!!  Click here to comment on this image.
