the drill bit set finally came in today, so was practicing on the broken box,
(sorry for the photo quality = .=, old sony doesn’t work well under low light…)
on the back it seems flush with the back of the gearbox,
but from inside it looks a bit uneven, or could be just lighting issue, i am no sure,
i free-handed it, not it’s def not gonna be perfectly flat
how crucial is it to have it perfectly flat?
and if it has to be perfect, what could i use as reference?
coz nothing seems flat on the inside of the gearbox
