Instructions
Create a template for the activity top for the train table. Many train tables have a removable top, which will make it easy for you to use to trace onto your plywood. Lay the activity top directly on the plywood and trace it. Many removable tops come in two pieces. In this case, trace each piece separately. If the top of your train table is not removable, you will need to measure the width and length of the table and then sketch a rectangle of those dimensions onto the plywood.
Cut your tabletop shape from the template you traced onto the plywood. Use a table saw to make the long, straight cuts. Then use router, jigsaw or saber saw to round the corners of the table to make them safe for children to play. If you cut your table in one piece, cut it in half after you have already rounded the corners. Cutting it in half makes it easier to fit into the train table and also makes it easier to store when not in use. Lay the pieces on the train table to ensure that they fit before moving on to the next step. If the pieces are too big, use the table saw to trim them down.
Sand the activity top. Pay careful attention to the edges and corners and also sand over the top and bottom of the table to ensure that there are no splintered areas.
Paint the tabletop. Use a different color on each side, which will essentially give you the option of two different activity tops. Remember to paint the edges as well.
Decorate the activity table. You can paint roadways for toy cars on one side and letters and numbers on the other. Or you can paint any designs that will meet the needs and interests of the children who will be using the table.
Seal the wood with two layers of polyurethane clear coat. This will protect the table from dings and dents, make it easier to clean after a day of hard play and reduce the chances of a child getting a splinter while playing.
