Bicycle Helmet Mirror for $2

Step 4 Attach the frame to the visor

Use small screws to mount the tabs and wire frame to the visor. Use a flat washer and a toothed washer behind the nut. The flat washer adds rigidity to the aluminum tabs. The toothed washer keeps the nuts tight. Use a scissors to trim sharp corners from the aluminum tabs. The screws may also be shortened with a grinder or any other suitable tool. The "L" shaped bend in this part of the wire frame keeps the mirror from rotating up or down. This general design also eliminates any need to weld or braze anything.
