Default 4 blades propellers

Hi,
Could somebody explain me how are made the 4 blades propellers (or point some dedicated site ?) : I can't imagine how are disposed the different layers ...
Sorry for my pour english,

Here's a picture from a Paragon catalog showing the construction principle of a 3 blade propeller, which they felt had a much stronger hub than a 4 blade.



Most of the 4 blades I've seen have had a similar type of arrangement, using a square step-cut instead of the tapered cut shown above. The 4 blade hub does have some inherent weakness, however.
