I’ve installed A LOT of Euro hinges but, to be honest, I still get a little squeamish about punching that big 35-mm hole in the back of a finished door. If the cup distance, the distance from the edge of the hole to the edge of the door, isn’t right, the hinge won’t offer all of its available adjustment. Or, if you didn’t get your door dimensions just right, the cup distance could be a make or break on being able to use the door. Here’s a very inexpensive insurance policy that’ll give you the confidence to drill your doors.
Step 1: Cut a piece of scrap that is exactly the same dimension as the width of your door.
Set up a fence on your drill press and drill a cup hole in your test piece. The distance from the edge of the hole to the edge of the door is typically 1/8” to 1/4″. Use 3/16” as a starting point.
Turn the left-to-right adjustment screw until it’s at the center of its travel. Do this by turning it clockwise until it stops, then turning it counter clockwise until it stops, counting turns while going counter clockwise. If it spins two turns, dial it back in clockwise one turn.
Hold the test piece in place on your cabinet. Whether it’s an overlay or inset door, this’ll tell the story. Be sure that you’re holding the case mounting bracket flat against the inside of the case. This can be awkward to handle, so it pays to keep your test piece small.
Check the overlay or inset reveal. If the hinge side is too close to the case (inset door) or has too much overlay, decrease the cup distance. And, of course, vice versa.
If you need to change the cup distance, drill and check another test piece before you drill the door.
Once you’re confident in the cup distance you can breathe a sigh of relief, drill your doors, and mount your hinges.
