Ken. Yes. Bamboo, being a silica composite, can be deformed under temperature. Patience is key. You have to insert a rod, bare metal wire or stick to prevent the diameter from collapsing/pinching off. Then heat the part slowly, while bending, slowly -and while not burning it.
Another fun fact: Untreated Bamboo has a short life span. Being a grass, it grows to adult size within the first year, then spends a short 3 or 4 years getting thicker, then succumbs to mold and dies off. This why it needs to be heat or chemically cured to lock it in. I have bamboo hiking sticks that are almost ten years old, but leave one outside, unpolished, in the weather for even a month, an it starts to decay. I now preserve them with Howard's Butcher Block conditioner.
Another fun fact: As these are smoked, like any wood, they soak up the tars and begin to form a Patina. Whether or not this contributes to preservation will be interesting and beneficial. Use it or loose it? Hmmm.
