I have a question.  How do you flex to the anti-parabola accurately?

i HAVE FOR YEARS, BEEN MAKING 6" PARABOLAS BY MAKING THEM SPHERICAL then
warping them to the " anti-parabola", repolishing the piece back to sphere
and then dismounting the piece all in the temperature controlled
equilibrium of my optics lab. This was a result of discussions with Martin
Sloan of Escondido in 1961 and with Art Leonard in 1969.
The technique has worked well for me when using well cured RTV (clear) as a
bonding agent.
