Little tip:
If you need to work out the dimensions of something but don't have decent measurements (or can't quite be bothered to calculate it), imaging software works a treat.
We designed a shell as a safety cover for a component earlier but I forgot to analyse it to get its volume and other properties. However, if I draw the shape to scale on Illustrator, I can inspect it and get the volume as a representation of the black pixels to the white background. Thus, I have dimensions!
I did it last year to find out the mass of a turbine blade. It works rather well.
