Someone mention not being able to do a good job installing hinges so I hope this helps. I tried to make it as straight forward as I could.
Here are the hinges I used. I just picked them up at Lowes. Also in the picture are some rubber feet I used to keep it in place and from scuffing up the counter top.
I mounted the hinges 1 1/2” from each end.
Then I clamped a small piece of wood to the bottom to give me a good edge to line things up with.
What you want to do is to have the pin in the hinge centered on the edge of the bottom. Using another hinge as a spacer worked for me.
I used a sharp pencil to mark for the holes.
Then I center marked the holes with a awl.
Then drilled a hole for the screws I would be using.
When I put the screws in I leave them loose until all three are in.
Then I tighten them one at a time. If one of the screws make the hinge go crooked then loosen it and use what ever combination of screws that make it straighten up. Usually by adjusting the screws you can put the hinge on nice and straight.
If not leave them loose until you have all 6 screws in and try again using all of them.
Then I just used the package the hinges came in to set the gap for the lid.
Then mark the holes, drill and install like before.
