Regular, old Q-Tip swabs, sans cotton ends are tigthly rolled, easily manipulated, and, with a bit of alcohol wetting, will easily bend without binding or crimping. Furthermore, they can be unrolled to obtain a smaller diameter. They will also form the core of a larger diameter cylinder. For those wiring radial engines, here is the perfect material to make collector rings in any scale! They will be great for exhaust stacks. I am sure you folks will think of many other uses.
