Here ya go Rock_Ten,
This is what I got a mat to weld up for me the other week. It still needs to be tested out but I haven't gotten round to it as iv'e been busy constructing my new BIG trailer plus adding a wooden box etc to a trailer I bought the other week.
Hitch (rose/heim joints) on bike to recieve trailer. One on each side of wheel.
The trailer hitch part I had my mate weld up - (still have to attach frame to it).
Frame will be clamped (until welded) to the white stem that revolves.
Keep yer fingers crossed that itall works this time
Tom
