COMPONENTS I've tried to make making mallets as easy as possible, with the most common materials. You probably have these materials lying around:
Disc A piece of plywood which is at least 13cm x 13 cm and is about 2 cm thick.
Handle A PVC tube with an outer diameter of about 4 cm and a length of about 7 to 8 cm. You can consider the option of using the end of a broomstick, if it has the right diameter. This handle can be a little shorter.
Scratch preventive material An old piece of circular sandpaper (those with soft backs). You can also use a piece of felt.
TOOLS -Drill and Hole saw (with an outer diameter of 9.5 and 4 cm) -Hack saw -File and some sandpaper -Close contact glue
