Since a piano is such a heavy musical instrument, it can be hard to move. By making a dolly for it, you can put the piano on wheels, and a multiperson moving project becomes a task one person can do with relative ease. All of the materials used in making the dolly can be found at your local hardware or lumber store.
Lay out all of the 2x6's. Take one of the casters and place it centred at the end of each board. Use a pen or pencil to mark where the holes of the caster will be.
Use the electric drill to drill a hole at each mark you made with the pen.
Take one of the larger boards and one of the smaller boards and place their ends together to form an L shape so the holes you drilled line up with each other.
Take one caster and line it up with the previously lined-up boards. Make sure the small board is on top of the larger board and the caster is on the bottom side of the larger board. Insert a single bolt into one of the holes, and use the wrench to tighten the nut on the bolt. This will hold all of the pieces together while you insert the rest of the nuts and bolts. Use the wrench to tighten them as well.
Continue to secure the boards and the casters together until all four casters have been bolted tightly to the boards.
Spray the rubber coating onto the surface of the 18-inch 2x6 boards and let dry for several hours in a well-ventilated area.
Hardwood maple is the ideal wood to use because of its stability. Using a weaker wood will compromise the stability of the dolly.
Do not inhale any fumes from the rubber coat spray. Use in a well-ventilated area.
