Nicely done. I might go with a bit of a longer nail when reinstalling the slates, as it didn’t seem to have much depth on the wood there. But great technical skills fella. Nice to see someone actually take the time to remove the tiles and properly fit the valley rather than try to shiny some junk in from the exposed portion.
Rubbish work,strip out in a pyramid so you only got one slate strapped,also get rid of that toffee hammer you will brake slates,also don’t nail the lead both sides only one side or it will rip eventually! It can’t move,it’s good practice to number slates when stripping👊
