Just fitted an admittedly cheap bull horn to my beater, and a quill stem with a single bolt. It is all wrapped now but has slipped twice during riding. I've tightened it as much as I dare but not confident it won't do it again. Now I think about it the cheap bar had no markings or marks in the centre and this lack of friction is probably the problem. Now the bar is wrapped I'm loathe to unwrap it as it wasn't cheap bar tape, but I'm wondering if anyone would consel roughing up the contact area of the bar, and how this may be acheived. As I said it is wrapped but I can expose the area required. Drill? Hammer and screwdriver?
