Exceptional work - you should be very proud.
A quick tip before dropping the playfield in. Don't fully populate it as it will be too heavy to lift and you risk scratching the internal paintwork. Put some thin rags or newspaper down the side of the inside of the cabinet.
Better still - If you are not installing mirror blades, go to bunnings and find a roll of adhesive backed felt. These are used for the bottom of chairs and tables so they don't scratch the floor. You will find them perfect for sticking along the wood guides on the playfield. Then you will NEVER scratch the internal paint work. I place them the full length of the wooden guides. They will also protect the section near the swamp with the ball gate - this ALWAYS scratches the side wall of the cabinet.
