Bike fenders from recycled bike tires

Step 4 Front Tire: Finish and Mount it

With both parts welded and test fit, the next step is to paint the metal so it won't rust. If you used copper this may not be needed. Once the paint is dry, you can mount the fender to your bike. The top arch and tab are bolted to the top of the fork at the brake caliper mounting hole. Nothing more is needed at the top. Make sure that the fender-tire does not interfere with brake operation. With caliper brakes you will most likely have to trim the fender so it remains behind the brakes. Cantilever and V type brakes have enough clearance so the fender-tire can extend through the brakes if desired.

At the bottom U loop, poke some holes in the fender tire where the loop crosses the bead so that you can push some wire or string or zip ties through the hole and attach the tire to the U loop. See attached pics.
