Cargo Trike - when it's all said and done...
This project was a team effort, and I wish to thank the people involved.
First and foremost is Juergen Weichert, who said to me "I have the welding tools, you need a trike, so let's get together and build one!'. Juergen only wanted to have his costs covered, and looked at this project as a way of honing his welding skills. He was also extemely patient, and helped me sort out design issues (of which there were many, since we were not using plans, but working from photos, and had to modify things to suit my needs). He also gave me full run of his basement workshop, and that made a huge difference. Thanks also to his partner Julie and their two kids for putting up with me sawing away in their basement, or just in my coming and going up and down the stairs with various tubes of metal in various stages of joinery. They even fed me on some evenings when it got too late, and I am forever grateful for their kindness and generosity.
Secondly is Richard Guy Briggs, who offered to put together the electrical system. I knew I wanted the trike to have running lights and turn signals, etc. but I am not well versed in matters electrical. And believe it or not, you are out of luck if you want to buy an off the shelf system for your HPV. But Richard wanted to make someting universal, but of course there has to be a ptorotype. He designed the circuit board and switching, and also helped me sort out what lights to use. The resulting LED-based system draw only 4 watts of power! We worked well into the night to get the trike ready for its debut at our local St. Patricks Day Parade, where it performed without a hitch.Thanks also to Jody McIntyre for finding me a place to paint the frame, and he also recently did a rebuild of the switching circuit due to some teething issues (he and Richard will hopefully have a write-up about this circuit soon). Lastly, thanks to Dan Kavanaugh of Organic Engines, who let us "steal" his design. Dan was not able to provide plans, but did give us some tips via email and phone, and we worked from there with the photos on his webpages.
