Dad used the drill to make 3 holes in the top of the can. 2 holes were for the bridge and 1 was for the neck. I put two screws in the can to hold the bridge in place. I had to go from the inside of the can. Dad and I put the neck board into the 2 holes we made in the coffee can. I screwed down through the top of the coffee can to the neck to hold it together.
