In reply to Siward: Go onto ebay, buy a cheap tap & die set, use it, then re-ebay it. overall it'll probably cost you a few quid. Or Phone optimus, see them the sob story - I find it hard to believe that a nut and bolt cost £40! Failing that, take the hole thing to somewhere like machine mart or HSS Hire, and explain that you want to use it for 5 mins, they'll probably let you use it for free.
