Subject: AW: fracture due to vibration


Hi,

I welded a 4mm thick metal piece to the frame, drilled a hole in and welded
a nut behind that hole, so that the original screw fitted in. Then I
exchanged the screws to stainless steel versions and never had trouble with
this. The original holders are too thin and therefore too weak.

After three breaks of the five stars crash bars I changed to the Africa
Queens bars. We'll see, how they work, up 'til now thei're OK. ANd they're
much more stable designed.

take care - Marcello.
