Nitonel straightens itself , just check the operating temperature , buy it off Martin on ebay search pole float making materials or google Finesse floatsI want to make some pole floats with wire stems for use on rivers, so have some ideas of the type of thing I'm aiming for.
I've seen some ads from 'boutique' makers where they use what seems to be a very springy wire.
I've been doing some research and I've seen some references to nickle titanium 'flexi wire', seen it for sale, but it comes in 3m lengths and coiled.
Is there a trick to straightening it? Any other suggestions or ideas? (plan B would be to buy some bicycle wheel spokes).
