More work today on the hitch.
I had some other things going on today so I didn't get as much fabrication time as I could have. I will pick things back up tomorrow.
What I ended up doing is welding in a square to the "front" of the tongue bar sleeve and cutting a matching angle to the bracket the horizontal pivot is on (130deg angle) so the horizontal pivot is perpendicular to the trailer. That part I tack welded to test fit and it needs cut apart and moved - I can't get the horizontal pivot assembled - see pictures. That is the good thing with custom fabrication - I can play with part fitment and make it work. Yea, I could design it if I was careful with measurements and drafting everything but I am not going to that length on this project. Its just rough fabrication for now. When I get to my full custom trailer design at a later date then that will be "designed" - part of the reason I am working with the stuff I am here - to try some ideas and see what I want to change or do differently next time so I can add those changes in to that new design.
Here is the hitch pivot on the bike side only turned all the way to the "right" (how the pivot would move when turning to the right). You can see there is some part interference. That is easy to change - I can cut the protruding part down without loosing much. There is a lot of weld on both sides of that T joint so it is pretty stout.
