Losing one of the externally threaded nuts/slotted insert that holds the RA worm and bearing in place has a similar impact. 🙂
3 hours into the search for it, floor, table, hall, rest of kitchen and will be searching conservatory tomorrow (in case it got stuck to soles of shoes). Even checked the rubbish bin in case it got caught up with a greasy tissue. I’m really not enjoying this activity very much so far… 🙂
