I cut and welded, and it is better now..

It is now just about ridable right off. I went down the alley for a few 
seconds, then ran out of maneuvering room. I really need a parking lot for 
practice of the feel. The turning radius is so large, relative to an upright, 
that you need react quickly at low speed when the frame/body starts to lean 
over.
The handlebars may not turn out to be useful, we'll see. In any case I intend 
to move them under the seat for mounting the brakes and shifters.

is a closeup of the pivot; I thought that it would make mounting handlebars, 
and maybe a damper, easier. It also gives the minimum trail possible.
It might be worth making the angle more like 70 degrees, but my grinder died 
and I ran out of welding wire, both within five minutes.

BTW; it seems tieflieger.net is unavailable (?)
