3. Two small washers that fit over the rod.
4. C-clips that are just smaller than the rod or some small wire.
Step 2: Prep the Screwdriver and Rod

Step 3: Bend 2 90s in the Rod and File the Nipple Driver
1. Bend the rod like in the pics. Mine have a 1.5 inch spacing between the bends.
2. File the nipple driver by first taking a chainsaw file and filing the tips sides all the way down until you have a screwdriver.
3.Now take a flat file and file down the top making a nipple that will go into the nipple.
4. Test it out. Repeat step 2 if need be.
Make shorter and longer ones to ensure you build a round wheel. See pic
Step 4: Put It All Together
1. Stick the rod through the screwdriver.
2. Add one washer and c-clip.
