CAD drawings

I experienced it is a good idea to make a CAD drawing of a project before execution because it makes you discover flaws in your thinking process.
I started the project with making a rudimentary drawing of the complete bike and I am bit for bit making separate drawings of the different parts and see how they fit together. I will try to find a way to post these so you can download them for own use.
As an example, I'm posting a link to the front wheel bearing housing .dxf file. Right click and 'save target as'.
