I'm back! Sorry, no combination lock today, but that should be next. Anyways, my brother got me a NERF Zombie Strike Doublestrike blaster for Christmas, and I decided to modify it to be wrist-mounted!
Step 1: Disassembling and Cutting
Take all of the screws out
Take all of the parts out of the shell
Cut between the two Sharpie marks on the back of the shell, the lower part of the shell, the trigger, and the spring lock
Step 2: Creating the Back
Glue four of the pieces together with wood glue and wait a day
Glue the other piece in so that the larger pieces fit into the groove and the new piece is touching the trigger stop (see photos) then wait one day.
Screw in the spring lock right at the corner (Closer than me)
Step 3: Reassembly
Should be simple enough if you follow the pictures
Don't forget to put the screws back in
Step 4: Attaching the Back and Spring
Drill holes where the Sharpie marks are (to keep pressure on the nails, drill until the bit has almost gone through and then push the nails the rest of the way through.
Tear off two half-meter strips of Duct Tape and fold them in two, then fold another piece around them (You can also just use a small belt or some fabric)
Fold the pieces around the back section equally, and tape them in place
Fold the ends of the duct tape, and stick a nail through the Duct Tape and holes in the gun
Take the nails out and attach the spring to the back
Reattach the back
Cut a small triangle in the back, leaving a small strip above the triangle
Try to cock the gun. If you can't, or it is difficult, trim the corners of the spring rod.
Step 5: Wrist-mounting and Touch Ups
Make or use two elastic bands about the size of your wrist and lower arm near to the elbow
Attach the smaller band at the front, and the larger band at the back
Shave down the nails
Trim the trigger stop, drill a hole in the trigger, tie a string to the trigger hole, screw in a eye screw, thread the string through, and attach a ring big enough to fit over your thumb. Make sure the string is the right size for you or your way of wearing the gun (Last photos). This allows you to fire with your thumb instead of your other hand
Create a pouch or attach a elastic to carry extra ammo
Wear the gun however you want
