This is a mockup I did today of the steering knuckle. The real knuckle will be built out of welded flat steel but this aproximated the shape nicely, plus I got to play with the rod ends I got on eBay!
the journey of attempting to build a recumbent tadpole trike
I decided to do a crude mock up of the trike to get an idea of the size and where things would end up. The front has 20" wheels I "borrowed" from Jack's bike trailer, they are exactly the size and type of wheel I need. The read wheel is a 26" but the real tike would probably use a 24" wheel. Yes, I know the seat is too high ;) and yes, that is a crutch used as the rear fork.
This is the frame design I am going to use with some modifications. It is a Spitfire which is a later version of the Thunderbird, both designed by Rickey Horwitz. Rickey makes his frames from 6061-T6 aluminum, but I will build mine out of a combination of mild steel and aluminum. The all aluminum bike weights only 28-32 pounds (bare frame is 18 lbs)!!! Mine will be heavier, most home builds are around 50-60 lbs. I decided to draw on other people's experience and not re-invent the wheel for a change. I think there is a pun in there somewhere... Check out the Links section of this blog to see more detail about this and other designs.
