  • How do I bend balsa wood for an arched balsa wood bridge?

    The balsa wood beams are about as large in diameter as chopsticks. I have heard of using ammonia, alcohol, steam, etc, but do not know which is the most reliable. I need a system for bending that will keep the wood strong after the bending process has been completed. Also, what is the best way to keep the wood bent after the initial bend (a mold?)
