Wood Propeller Fabrication

Step 1: Obtain Propeller Cross Sections

First you must have full size cross sections (about 10, from root to tip) of your propeller. There are tools online for designing propellers, but you will need some CAD software to create the drawings and 2-D cross sections. I used CATIA, but any 3-D modeling software will do. (I also have a detailed instructions on design of propellers here (www.aerodyndesign.com) Of course you will have to print out the cross sections of the propeller on to paper, at full scale size. Because you will need to cut them out and glue them to thin peice of aluminum or tin.

Hi, i have a question about your cross section. How can i print out a full size copy of it? it says it should by around 48 inches in length. im thinking about printing parts of it on many sheets of paper and then gluing them onto the templates. could you tell me how to get a full size?

Well you can print it out using the tile option and then cut it out and tape it together. Or u can take it to Kinko, and they can print it on a plotter.
