I love this design. It has elegant simplicity, people (especially engineers) tend to over design items, this is simple and effective. Do you have any specifications on it? Size of the wheel, the off set angle of the hinge point, the length of the square tube I am assuming is 1" square steel? Bolts used etc...That type of thing?
