Bike fenders from recycled bike tires

Step 3 Front tire: Step 2

With the lower U loop finished, the next step is to make the upper mount that bolts to the caliper bolt at the top center of the fork. Take a short section of metal rod and bend it into an arch that matches the curve of the tire you are using for a fender and that will easily clear the tire on your bike. Then cut a tab that will hold this arch at the desired height above your tire when bolted to the caliper hole in the fork. You will have to measure your own bike and adjust as you see fit. The pic below shows the idea.

With the tab welded to the arch, double check your measurement and then drill a hole for mounting the arch. You will need to cut a slit in your fender-tire to push the tab through and then you can test fit the arch to make sure that everything fits right.
