i heard of people cutting up an old tube and melting it or something to make a patch. how exactly is this done? i dont need to it to necessarily hold up to heavy riding because its for my brother who just just rides it up and down the drive way and the tires only hold like 30 psi. thanks.
Use rubber cement. DO NOT use the fast drying cause it cracks and peels off the rubber. I wipe the tube and the rubber for the patch clean with rubbing alcohol. Put the cement around the hole, wipe some around on an old tube (just nice and thin), and let it COMPLETELY dry. Cut out your patch and place over hole. Works every time if you let the glue COMPLETELY dry before you put the two together. I've patched some pretty big holes too. I've done this for years. Super Glue works sometimes, and sometimes doesn't. It turns hard and brittle and cracks off the rubber when the tube is filled with air. Just use straight up Elmer's rubber cement. Works like a charm.
