Guestimating
that more than 20°C of heating should not be done to keep the whole
thing in a easy to handle range. Then we would have a maximum pulling
range of +/-230ppm, which means +/-10um precission on a 10cm diameter.
This is still a very thight tollerance. Not impossible, but not that
easy either.
