Made an adjustable Football rebounder to practice first touch in soccer. There is almost no loss in ball speed due to the tight strings. It is like a tennis racket. The string is a nylon string meant for weed whackers. it is tightened with bolts on the side. The rebounder can be aligned in different angles so you can practice retrieving both high and low balls. There will be a youtube video about the build at some stage.
