Introduction: Bicycle Chain Gear Whip

A chain whip is a bike tool. Here's how to make one.

Step 1: Find the Parts

- You need a sturdy round bar or flat bar. I used a smooth round bar a got from the rails of an old printer. The longer you use the more leverage you'll get. About 12" will work fine.

- Some old bike chain. 12" or so will work fine. I find that the farther you wrap around the gear the better the chain holds.

- A welder or POSSIBLY you could put a hose clamp around the end and the middle to secure it. If using a flat bar, drill and bolt it.

Step 2: Assembly

Pictured below is a commercially made chain whip. I find that my method works fine too. But 5-10 chain lengths over 3"-4" should work fine for the "secured" portion. Simply leave the rest unattached. shows a chain whip in action.
