littleblackflash Posted December 20, 2009 Report Share Posted December 20, 2009 Hi, I need a 12mm swinging arm spindle to complete my 1972 Bultaco Sherpa. Bultaco UK don't have any and don't know when they will make any? Alternativley, any one know someone who could turn down a 14mm spindle?

feetupfun Posted December 20, 2009 Report Share Posted December 20, 2009 Options 1 Buy some 12mm threaded rod from the hardware/building supply shop 2 Theres a person making stainless steel replicas of many old Bultaco screws, plugs, axles, nuts etc and advertises on eBay 3 Any machining business could thread the ends of a piece of 12mm steel rod for you Quote Link to comment Share on other sites More sharing options...
