i know this is an old question but it pops up on google first, so for future breakage, the way i do it is with super glue and tissue paper...just wrap a couple layers of tissue around the break and saturate the paper with super glue. works like the baking soda super glue method, but a lot easier. the paper and glue dries hard as !&&* and it is easy to reinforce or add layers to certain parts. its like instant cement, looks like crap though but hey if it looks stupid but it works it aint stupid
