Truculent Teenager's model 'nitro' car is in bits on his bedroom floor again and we've found that the pivot pins for the suspension wishbones are bent. They're about 30mm long 3mm dia screws with a horrid little self-tapping thread at the head end and the rest is plain shaft. Option 1 is to keep on paying silly money for replacements from Apex Models (no doubt the replacements will suffer the same fate ...). Option 2 is to get a bit of 3mm dia steel, silver steel or even brass, cut it to length and fix it in place. Options for fixing it seem to be (a) threading the ends and loctite-ing or lock-nutting nuts on (presumably a 3mm rod will take an M3 thread?) or (b) finding a source of those fasteners that look like crinkly washers and push onto a shaft with tangs so they won't pull off (anyone know what they're called?)
I can get rod and dies from e.g. Folkstone Engineering Supplies
