About The Project:

The airplane is a home-built, scratch-built Zenith CH 750 STOL. Building from plans/blueprints is a challenging way to build an airplane, since most of the parts you use to build it are not prefabricated. I chose the Zenith CH 750 STOL for its rugged design, its STOL (Short Take-Off and Landing) characteristics and its aluminum construction. Zenith Aircraft Company has designed this airplane so that it can be built from scratch or from a kit by the average person. They provide excellent technical support for both kit and scratch builders. In addition, I'll be installing a 1965 Chevrolet Corvair 164 cid horizontally opposed, air cooled, 6-cylinder engine, with special conversion parts to make it suitable for airplane duty. This is what the airplane will look like when I'm done, although I'll have a different paint scheme:

Calculating Developed Length

In this video, I talk about calculating developed length for your parts blanks, using variables that are specific to my bending brake. I've learned the hard way, that every bending brake, whether it is a professional, industrial grade brake or a DIY brake, has its own bending characteristics. You absolutely have to experiment with those characteristics and learn exactly how a part needs to be measured and where the bend lines must be placed in order to bend the part to the correct size. In my next post, I'll talk about how I had to scrap an expensive part because I didn't take the time to verify developed length properly when using a different brake.
