"Modern" Propellers
This 6 foot Sensenich propeller demonstrates typical features of a propeller manufactured since the 1930's.  Notice the symmetrical edges of the blade, the light wood, the length of the metal sheathing and the 6 bolt hole pattern.
Some of the most common manufacturers were Sensenich, Hartzell, Flottorp, Fahlin, Lewis, S&S and many others.
Identification Help:
Sensenich also has a website listing current propellers as well as serial numbers and dates of manufacture.  You will need to look through the aircraft listings and find the drawing number that matches your propeller.  Ignore the "W".  A newer,  more convenient way of looking up a specific design number is available on Lamar Bevil's site,   Modern Wooden Propellers.

August, 2004 -  I am pleased to announce that Lamar Bevil has taken on the task of developing a second propeller web site that will deal with modern propellers.  He plans to organize the many lists of drawing numbers from different manufacturers into a usable comprehensive listing that should help in identification of many common propellers.  Please visit his site at www.modernwoodenpropellers.com , which is currently under construction but will grow as we add new information.  As I've mentioned previously, my personal interest is in the early wooden propellers, so it will be helpful to have a site dedicated to props like the one shown above.
December, 2005- Monte Chase has recently published a site about variable pitch wooden propellers.  Go here to visit his web site.
January, 2006 - NEW FEATURE - We now have a Wooden Propeller Forum in which to post questions about specific propellers or propellers in general.  Please register and join in the discussions!  It includes instructions in how to add pictures to your post.
