I took the cutting head of my cordless hedge trimmer apart as it wasn’t cutting properly.
Couldn’t find anything wrong or anything that I could repair so went about reassembling it.
The fixing bolts wouldn’t tighten and then I sussed they must have been secured by nuts and not the aluminium body itself.
Sure enough 3 small nuts floating around in the hollow section.
A couple of hours later, using a thin stick, magnets and wood pegs I finally got it together!
I assume in the manufacturing process they must have something better, perhaps tiny Chinese fingers .
