Yes, the torch will work but you must keep a good distance from the wood. Small fires will cost you less in the long run but the torch saves a lot of time.
Well, I just thought that it had to be a HOT source of heat, and had to be concentrated to straighten stuff. Now that I know charcoal works, thats what Ill use.
Thanks, squirrel
If the bamboo gets too hot you will damage it. If it starts to turn very dark, it's toast - literally... lol.
If it's just about too hot to touch, it's the right temperature - wear gloves anyway to save your finger tips. Bamboo gets very 'plastic' at the right temperature.
Use a straightening tool, it's what they were invented for. I'll have to post the one I made out of scrap. It's got a slot cut in it and I used a dremel tool to dish out the tool on the sides where the shaft fits so you don't put 'crimps' in the shaft. The latest ones I've made can be used with either hand (I put the 'dish' on both sides of the tool. (I've just got to find my camera now... )
