The self-propel on my LB pusher quit working because the hook at the end of the cable that runs up to the handle broke off. Are there any known good ways to fix these? I'd rather not have to buy a new cable when the only thing that's wrong is it's missing that last 1/4" of pot metal at the end. BTW, the missing bit is gone so glue is out but maybe make a new one with JB?
