Pitch your props

This is how I pitched the props on my Boeing Clipper 314. With 4 engines 12 props I didnt want to leave it up to twisting with pliers. The 1st photo shows all the parts needed. The 3 prop blades, scaled from a photo. The 3 triangles. One is notched to make the pitch plate. On a good 120deg. pattern center the back plate. Glue the pitch plate down. Next photo shows the blades glued down in climb half up onto the pitch plate. Use the 120deg. pattern to align the blades. give it a little time to dry then add the face plate triangle. I used a HELIX angle and circle maker to layout the pattern. They run only a couple of bucks and with one you could layout a pattern for even a turbine face and it draws circles without a pinhole in the middle.

Useful info and a very useful tool. Many thanks.

I really like the model of the Boeing 314 that you are building from Gary's design. Those were beautiful flying boats. BOAC was still flying them in and out of Baltimore Harbor when I was a kid in the late 1940s.

I've given up laying out angles. Now I make a template with Google Sketch-UP, and cover it with wax paper. A blend of old and new techniques.
