X & Y BUTOTN Tools you need: 1- Step Drill Bit 2- Hot Glue Gun 3- Scalpel There are two holes in the board to guide you how to drill X & Y holes. Drill the holes using the Step Drill Bit FROM INSIDE. The holes should have a slight bend shape and this will be made by the drill step bit. Trim these parts in the buttons . Place a little glue on the buttons. No need for RUBBER PADS. Finally! It should work just as well as the original buttons :D .
