From my other thread:

Here's a picture from the other day. Please excuse the hitch arms, I haven't ground down the latest welds nor repainted them (they were black):



This was welded from scrap metal and bike parts. I got the paint for free from the local dump. The fabric for the lining was purchased new.

If anyone is annoyed that there's no pictures of the hitches, that's because they're broken (again), haha. There are details in this thread, though: http://www.bikeforums.net/showthread...-as-I-go-along
