I want to make bamboo bike like Craig Calfee and so many others have made, but if possible, I would rather not use epoxy, which is not biodegradable.
A bamboo bike has a frame made of bamboo, held together at joints by hemp-epoxy (or fiberglass-epoxy / carbon fiber-epoxy) composite lay up by hand. Is there any natural/diy alternative to epoxy which can be used with hemp fibers in a similar fashion to hold the joints strongly?
I want to use a truly biodegradable polymer, even if synthetic. Even better if it can be diy homemade concoction. What did woodworkers use other than hide glue before PVA and Epoxy became so prevalent?
I'm looking for a plant based or synthetic non-animal sourced biodegradable polymer. Isn't there something one can make from plant proteins similar to hide glue?
