Hi there, my first post on this great forum. I've not renovated a vacuum cleaner before but I acquired a Hoover Junior 350 recently and had it apart tonight. The aluminium fan is unfortunately missing 4 of its blades. I'm guessing fixing replacement blades on would be a tough job, or rather keeping them on! Would anyone happen to have a spare fan or any ideas on a suitable equivalent replacement? And how easy is it to remove the existing one? Thanks, Julian
