Here I have prop blank glued up and clamped together.

Here it is all ready to be carved.

Here is the center mark.

Next I cut the ends to the right DIA.

Then I traced the trailing edge template from the 36-18 prop templates, I just cut them down to 30" and added two extra blades.

Now I'm tracing trailer edge to the prop.

Heres the trailing edge.

Here is the leading edge mark and the top flat area mark.

These are what I'm using to carve out the prop, I use the chain saw blade to rough it out, then I used the sanding disk to smooth that out. After that I used a palm sander to flatten everthing out.

This is what it looks like after I'm done with the chain saw carver. After doing a couple blade I got used to it more and I cut the blade out to about 1/16" before the line.
