Just a thought, but if you'll only be using the extractor the once, then why not call at a bike shop where they deal with vintage bikes and borrow their tool they'll most likely have? I can understand you not wanting to pay a lot for the tool, but in my experience these are nearly always sold for quite high amounts, just due to the relative rarity value. Or if there's no bike shop like that above in your neighbourhood, another idea is check through the 'loan a tool' list on the LFGSS site, and there could be someone local to you (not me, unfortunately) who I'm sure would help you out. Not sure if I should mention the other site though
