Still measuring, designing, and doing the drawings as I go. Of course the reworking as I come up with new ideas as I go. So far used up three rolls of flux cored mig wire, about 6 mtrs of 25mm SHS, 3 mtrs 50x25mm RHS and 2 mtrs of 50mm SHS, and 4 stub axles ( 2 were the wrong shaft size and its too late to change them after they have been welded)
If needed, I have an idea to make an articulated hitch, the local trailer parts place has shafts and bushes that are suitable.
Any one have a 2nd hand towbar for sale to suit ST1100.
