Quoted from Mikala:Trust us, the less than 1 hour it will take you to completely break down the machine to a bare cabinet, will greatly out weigh the many hours of hassles you will come across from trying to tape everything off. Take a lot of pictures as you tear stuff down, put all screws and parts in separate labeled bags. It will be very easy to put back together. There is a great video on YouTube on how to take the side rails off in less than 5 minutes.
Great job on the River Boat. Great game.
You have to take it all apart. There's really no other good option.
