Heres the Mark I version, i used clamps in the end, held by M8 bolts, with wing nuts spun on and then trapped in place so they can't shake off by hitch pins. Foolproof...the holes through the tube where the M8 bolts go are lined with 10mm x 1mm steel tube to prevent the square frame...
its virtually the same design as the VW A frame thumbnail i posted. The detail we are discussing is how to attach the frame to the bike. I wondered if i could insert U bolts into the lower front wishbone arm, so there was two towing lugs, in the same way a car has a towing lug on the front...
Ah yes.
Fortunately, i don't need to tow it far, just locally.
its a cheap chinese quad, i use it to go to work on, but it had to be taken to the garage a couple of time, and each time its cost me £25 to get a tow there with it (they take it in a specially adapted short wheelbase transit van)...
Well, i rang the police station to ask, and some female said that as long as the quad can't wander about laterally behind the car, they she can't see a problem. Mind you, i don't think she was the font of all knowledge on the subject.
When you tow with a single bar, you have to have someone...
im just pondering ways to clamp the A frame to the wishbones, and the relative merits of several ways i can think of doing it.
One way i thought of requires a 15mm radius U bolt made of 6mm steel being inserted into the front leg of the wishbone on each side (theres 4 legs each side...
Im making an A frame to tow a quad bike behind a car, i need to know something because it affects the design.
Imagine a steel tube of an arbitrary length of 1 inch diameter, and 2mm thick walls.. It will have a specific inherent strength before load causes it to buckle or deform.
now drill a...
