Step 5: Assembly of gun grip and painting
You may went to tape the parts together at first to ensure that everything will fit together properly prior to gluing and or nailing the parts of the gun together.
Once the form of the gun is made, the slide with the bamboo skewers are attached. To clamp parts together for gluing, I would frequently wrap rubber-bands around the different parts to hold them together as they dry. That allows the parts to dry without slipping. It is particularly important that the bamboo skewer section is glued onto the gun in the exact correct position, otherwise the slide will not catch on the trigger or the slide will jam. When gluing this component on, make sure the slide moves easily and hits the trigger in the correct position to catch.
