I have the same story as many fans of Joerg Sprave. <br><br>I grew up shooting and making slingshots, bows, and various other weapons. After watching videos of his "crazy rubber powered weapons" I began making slingshots. With this new knowledge me and my nephew are now making powerful slingshots and other rubber powered weapons. <br><br>Thank you for providing your fans a place to learn and discuss this very addicting hobby.<br><br>Great job on the forum Thomas.
