Yes, its longer than the opening (because the post was not in line with the opening and I didn’t want it to swing through the other way), yes, the post is not level, yes, I should probably not have used an existing fence post, no, I will not be fixing it. But look at the fit on the diagonal. MINT
I’m partial to adjusting gates like that myself but I wanted to try just doing a really tight fit with wood. I may go back and add something later. Why do it right the first time when you can do it twice later?
Ah yes, the tried and true “measure once and cut twice” approach.
