Installing piano hinge question

    Hi. I need to install a piano hinge to the top sheet/ lid of a box I've made. I've used a hand router to make a rebate for the hinge on the underside of the lid and mounted one leaf of the hinge in that.

    Only problem is, when I put the top sheet on the box and line it up so the front edge of the lid is flush with the front face/ side of the box, the back edge of the lid is sitting a bit less than 1mm in from the back side/ of the box. This is how I'd like the lid to sit once fixed with the hinge, ideally, as I'd like the front of the lid to actually line up with the front of the box and look fairly seamless.

    Any idea on how I go could about marking out the hinge on the back side a little in from where it should be to allow this?

    I was thinking of masking up the back edge of the box that the other hinge leaf will be fixed into, folding the hinge backwards over the back edge (after unscrewing the other leaf from the lid obviously) and drawing around the shape of the hinge onto the masking tape to get a general placement. Then just edging the edge of the hinge leaf over that line a little to get the hinge sitting further in a little. OR just drill the pilot holes a little off centre from the centre of the holes on the hinge leaf e.g. slightly towards the inside of the box, in order to have the hinge sitting in a little more. All a bit trial and error that though, not exactly hugely accurate...

    Any better ideas? Thanks

    I would fit the hinge to the box and close it flat. Then lay the lid on to the box and, if I've understood you correctly, there will now be a small amount of the hinge sticking out from the back edge of the lid. If you mark the hinge where the back edge meets it (score the hinge with a utility knife) and where the ends of the hinge are, this should give you a perfect reference to fit the hinge to the lid.

    Hi thanks for the reply. Yeah I get what you mean, only thing is it's the box itself I want the hinge to fit slightly forward on... I would't mind doing it this way but I've already cut the rebate into the lid and drilled holes, don't think I'd be able to drill any more holes in the lid close to the original holes, or glue/ plug them with something small like toothpicks are the screws themselves are so small I don't think even a toothpick will fit in the screw holes.

    I like your idea about scoring the hinge with a knife to get the position right though. I think if I do that while the hinge is fitted to the lid and front face/ side of lid is flush with the front of the box, I could then remove the hinge from the lid and fit it that way, then reattach the lid to the other leaf?

    Yeah, that should work. Good luck.

    You will also find that cheaper quality continuous (piano) hinges don't always line up exactly and there can be a lot of play in them
