[моё] What I did today (though who cares)

I was taking apart a high-pressure fuel pump!
And then I spent a long time trying to put it back together, because the cylinders are assembled in such an interesting way that it remains a mystery how they originally managed to build it and fit it inside the block.
And I cut my hand, yep )

I don’t know how interesting this will be, but I’m constantly taking photos of the things I’m fixing so I don’t miss anything during assembly; I can post them here too )

Well, while there isn’t a pool of experts gathered here yet, only enthusiastic folks! Go for it! You can even embellish it a bit—hardly anyone will know.

Of course it will be interesting. And even more so if it's embellished with pleasant wording!
