Does anyone have experience of bending thin bamboo to make outlines, as on very old designs? I recall a method involving curling it round a candle flame but all I got was a burnt straight stick. I wonder if the ammonia trick works.

I don't, but a quick poke around found this video.  The clip shows fairly large scale work, but it ought to carry over to smaller scale stuff.  The trick seems to be to have a metal working surface between the heat source and the wood to both spread the heat and allow you to bend it.

Some interesting thoughts/suggestions here too

Some people use a candle inside a tin can, or a soldering iron but the best method I've found is to use a small light bulb. It has to be of the old incandescent type and you have to squint a bit but you can get good results.

Bill,
      There is an article in Aeromodeller by Doug Mchard when he was doing one of his twins that showed the process of bending bamboo using a a candle in a tin also using a soldering iron is another way of doing it.

I've used my soldering iron several times.
Just wrap the bamboo around the heat until it's to the shape required.
Works well, and easy peasy.

Bill bamboo has a resin that you soften with direct heat to allow the material to form.  Gossie's method works fine but my favourite is to form it around a pattern over an electric element  on the stove top.   Affix it at one end and keeping the wood tight rotate the pattern as you feel it give.  If you need 2 similar parts such as wing or tailplane tips double the thickness and split them once formed.. one of the nice properties of the material

The Doug McHard method involves cutting the bottom off a baked bean tin (other cylindrical tins can be used) and positioning a tea light candle inside.  The tin is rested on the open jaws of a metal vice.  Once lit the candle warms the top of the tin and the bamboo is stroked over the tin until the required curve is formed.

Thanks all, especially the article, Indoor. I'll give it a go. No wonder it didn't work for me before!
