Step 7: Finishing Up
You can now assemble the batarang. I glued a little plastic widget over the machine screw head to cover it. You can still take the batarang apart by unscrewing the furniture connector from the rear. This is why you want to machine screw to be fairly tightly in place.
When this is done, you are almost finished! All it needs is any final shaping and filing, a bit of sanding of the edges, and you are ready to paint. I used a satin black spray paint specifically for plastic, and bronze model paint for the wing bevels.
