Batarang from "Arkham Asylum" Game

Step 5 Making the Axle

Now make the axle of the batarang. Tape the two wings together in the final position, and drill a pilot hole though the center. Separate the wings again, and drill a hole in the pivoting wing just large enough to accept the machine screw fairly tightly (15/64” was right for me). Then through the fixed wing assembly drill a hole large enough to accept the furniture joint connector (3/8” was perfect). The connector needs to pivot smoothly but not be loose.

I then countersunk the machine screw hole in the pivoting wing, and, using the large 3/8” bit, recessed the other side of the hole to accept a small portion of the furniture connector. This was because the furniture connector was a little too long and I didn’t want the wing to be loose when folded up. I could also have ground down the connector a bit but this seemed easier, and it worked fine.
