On the 25 th March we blogged that we were about to start work on a reproduction Westland Widgeon propeller, working from original DE HAVILLAND AIRCRAFT CO. LTD drawings.

We have now created the 3D CAD model from plotting co-ordinates from the original drawings.  We have used our CAM software (Computer Aided Manufacture) to create CNC tool path programs for the CNC machine to make the propeller.  Below are some images of the CAD model and the original drawing.  The tips are drawn square as they remain attached to the parent material in the machine and are shaped by hand at a later stage of manufacture.

This propeller is the next to be machined so we will post pictures as soon as there is something to see.
