Wow......
Wow......I know you'll never do it, cause you can't.
If I were you I would put a wanted ad on here for one. I am sure one of the members could make you one that is cheaper but more importantly, safer. Esecially if are just getting one to test.The design looks efficient and practical. I have the ability to build one (especially with JS's tutorial) but, by the time I drive around to collect the material (fuel cost) and build it I would have at least that amount of money invested. So, I decided to purchase a W and if it does what I want, I will innovate a clone later.
