Support for tying the bands to the pouch of a slingshot - 2 clamps. There is another simplified design in which the mobile jaw is replaced by a hook. This tool ties the pouch to a cylindrical or flat band rubber. It consists of a body on which pivots an arm that acts as a fixed jaw to hold the rubber, and a mobile jaw adjustable in depth to keep the pouch stretched while it is tied. Necessary materials, in addition to the printed pieces: - 1 screw M6-40 mm with hexagonal head. - 2 self-locking nuts M6. - 1 threaded rod M6-160 mm. - 1 screw M6-50 mm with hexagonal head. - 1 screw M6-40 mm with hexagonal head. - 1 nut M6. - 3 washers M6. - 1 wing nut M6. Mounting - Attach an arm to the body with the 50 mm screw, nut and washer M6, leaving a little clearance for the arm to rotate freely. - Fix the other arm to the movable clamp with the 40 mm screw, nut and washer M6, leaving a little clearance for the arm to rotate freely. - Pass the threaded rod through the holes in the body and in the movable clamp, thread the normal M6 nut into the tip of the rod. - Put epoxy or cyanoacrylate glue on the side of the rod that will remain inside the mobile jaw and in the hole of the nut, as shown in the picture. - Pull the threaded rod until the tip nut fits into the hexagonal hole of the moving jaw. - Place a washer and wing nut on the other end of the threaded rod. Use - The tool can be attached to the edge of a table with a small jack. - Pass the rubber through the hole in the pouch. - Fold the fixed clamp to hold the loop that makes the rubber. - Pull out the pouch and secure it with the mobile clamp.
