Dear Steve,
How big a mirror would you make with your planned machine ?
I had constructed a mirror machine to finish a 30 inch aperture f/2.8 mirror and I can tell you that if your mirror is 16 inch or smaller it just doesn't worth to make the machine.
Reason ? Because you could spend only acouple of days to finish the mirror by hand. It would take you years to complete the machine.
Best regards

I am planing to use it for 12" and 16" mirror only, because I am tired of using hand to polish mirror; anyway it could be interesting to build such machine.
In addition, I am thinking of making more than 1 piece of mirror of each size.
Best Regards,
Steve

To build a mirror machine you need to spend ten times the effort than making a mirror alone. So it is just not worth it to try.
In addition you need a lot of engineering skill in order that the machine runs smoothly. Furthermore you need very best optical skill in order than the machine produces acceptable paraboloids.
All in all you spend a lot but earn little. May be it's better to put your effort and money in somewhere else.
Think twice !
