That was pretty funny ya got to admit :)
Dom you're very aggressive when people are trying to help. I'll unlock this thread as some good may come from it. Please google angle grinder injuries and also pay attention to the road traffic act. Ive seen the photos of your welds on that trailer and I hope you're taking the piss. If you kill someone towing with that you will go to gaol. In fact someone should ring vic roads or whoever the regulatory authority is in Mexico and have that thing defected and cashed in for scrap.
