That's brilliant Gadge!
[and Blue for the observation about the boss]

After Magic Catcher, I have learnt some valuable lessons about

Graham22 has twice left comments on my profile, trying to contact me.
I have tried PM, and have sent a message to his personal email.

In the meantime here is the sequence:
- 83 - alloy grass and hay band protector (flush against oil seal with lip downwards).
- 84 - solid taper boss
- blade holder with blade flutes facing upwards
- 85 new Belleville washer
- 86 locknut

All very interesting.
