Step 5 Tools you need

You will need these common tools for construction:

• Drill, ideally a cordless variable-speed reversible drill.
• Twist drill bits up to 1/4", and optionally a 17/64" bit.
• Phillips head bit.
• Square: a try-square, framing square, or speed square.
• Saw: a table saw or chop saw is good, but a saber saw or even a handsaw will work if you're careful.
• Clamps.
• Vise.
• Shoe rasp.
• Scissors, needlenose pliers, wire cutters.
• razor knife / box cutter.
• Adjustable crescent wrench for bolt heads and bike axle nuts.
• marking pen.

You may also need these less common tools:

• Step drill bit that includes a 13/32" step, for enlarging a hole in a metal angle to receive an axle.
• For making flanges from plastic bottles, a 1-3/8" hole saw for your drill.
• Bike wheel cone wrench. Jaw width depends on the wheel -- it might be 13, 14, 15, or 16 mm.
