I am about to start the machining of the prop hub. This is a drawing; the dimensions do not snap accurately, so they require rounding out in practice. LibreCad!
It's simple, but a bit dodgy. I have it on my hit list to learn another CAD program. I do have AutoCad installed on my other operating system, but have yet to get it to install properly.
Maybe learn FreeCad, open source, and can be used with this operating system - Linux Mint 17 - Which I love!
