A bike's moving parts will need tender loving care. For years I've used single speed bikes to avoid extra upkeep and simplify my toolkit. I've changed over to gears and have needed extra cleaning, parts and tools. If you ever remove the gears on the rear wheel (AKA cassette more generally known as a cogset) you will need a Chain Whip/Sprocket Remover.
Step 1: Why Would I Make One?
You can buy them at any bike store for about $20. I have a tight budget ... actually I'm cheap. Either way I like used tools. A 'real' chain whip is tricky to come by as there aren't many uses for one. There are legit DIY solutions out there but I'm too lazy (they also ask for other tools I don't have). I've written the cheapest/fastest/easiest solution I know of.
Step 2: You Will Need: Screws/Driver
These were all items around my garage. Your resources may vary. Clearly this won't need to be too particular but you want to make sure the screws can fit between the chain. Acquire a:
- Screws - 1" to 1.5" long
Step 3: You Will Need: Wood
Any board will do. The longer the plank the better the leverage you will have. The thinner boards are easier to work with. If I had to get specific I'd suggest:
- 1" x 3" x 8" seemed
Step 4: You Will Need: Bike Chain
This might be less available but easy to get. You might have one in the garage, find one on the road or buy a wrecked $5 bike for parts. I would recommend:
- 6" of bike chain
My house has many bikes, projects and wrecks so I am well stocked. I found the perfect length on the side of the road. It was super rusty but instructables has many rust removal solutions. If you need to unlink or break the chain you can:
- Get an official 'chain tool' to remove a pin
- Use a hammer, nail (or pin) and pliers to remove a pin
- Cut it with a hack saw?
Step 5: Attach Chain to Board
Screw the chain onto the board so the links hangs over the corner 3 to 4 inches. I secured the chain in three locations. If you're on a budget you could get away with one or two screws I guess? Buck up and go with three to make life easier down the road.
Step 6: Fasten the Corners
Screws two and three keep the chain in line. For extra credit screw a hole into the board so you can hang it on the wall.
Step 7: Enjoy the Friuts of Your Labor
You never need one until you do. Having this on the wall has been a joy. There are many videos, walkthroughs and ... instructables on the proper use.
