Just don't shoot anyone in the face. It's not nice.
Suction cup dart heads
clothes pins (x3)
3/4" thick hardwood, (I think I used maple)
misc. rubber bands
Step 1: Find a Template
I approximated the total length to be about 14", in order to keep it toy-sized.
Step 2: Make the "spears"
I secured them together with a dab of Elmer's glue to the ends of the dowels. Afterwards, I set them aside to dry.
Step 3: Mark and Drill the Trigger Hole
I first drilled a pilot hole with a 3/32" drill bit, and the trigger hole was drilled with a 1" drill bit.
Step 4: Cut It Out
I tried to approximate the curves of the handle, but any mistakes would be removed later in the sanding.
Step 5: Sand That Sucker Down
To make things go by faster, I used my dremel tool with a sanding disk attachment to smooth out the handle grooves.
Finally, I used 320 grit all over by hand. With maple, this makes the wood extremely smooth and even delightful to touch.
Step 6: Filing the Spear Groove
Step 7: The Trigger
Thus, I drilled 3/16" hole at the mouth of the clothes pin, as shown, to hold the end of the dowel so that the rubber band catches it
Step 8: Glue the Clothes Pins to the Body
I glued them to the body as shown with wood glue, clamped, and let dry.
I did the same with the trigger, approximating the distance between its end and the butt of the gun, taking into account the ergonomics of a smaller person's thumb's reach to pull down the trigger.
Step 9: Lock and Load!
I also added a short length of duct tape to the rubber bands where the trigger holds them in place, to reduce the wear.
I hooked the fronts of the rubber bands into the clothes pins as shown, and they hold pretty well. I can guess that these rubber bands would have to be replaced every few weeks with constant wear and tear, but otherwise it works perfectly fine.
Step 10: Fire!
So much win.
