Re: Building a fixed post mirror grinding machine. Update summary: Lots of work to get to this point. Things I need to probably change or fix: My gearing of the DC motor. I will need a slow speed for polishing (5 rpm), and faster speeds for hogging out and fine grinding (15- 30 rpm), so likely need to think about adding a gear reduction.

Making two matching 30 inch [0.76m] F2.7 telescope mirrors

The 13.2 inch meniscus acts like standard flat-back mirrors (as does the 20.5 inch x 2 inch thick Pyrex mirror), but the 25 inch is definitely floppy: I saw that during fine grinding as the blank flexed and scratched at 9 micron aluminum oxide, necessitating a return to 25 micron AlO2.

Re: Wonderings On Spin Casting Parabolic Mirrors, …

I'm talking multiple primaries, not folded scopes. I KNOW that mirror focal lengths must be matched, and there are BIG collimation headaches, and that mirrors off axis have coma probs (Long focal length may not be so bad), but I can get 4 or 5 finished 6" mirrors for less than a 12" mirror grinding kit.

8" F6 Mirror Grinding. For grinding tools I have read that it is recommended to use dental plaster or pure cement as a substrate. Then tiles are attached to this substrate either by glue or to embed them directly in the plaster or cement when the cast is made. Other tools used for hogging out also can be a metal ring or pipe flange.

The first design was a 150 mm F4 Newtonian (diameter of the main mirror 150 mm with the F-ratio 4). However, I was told that a F4 mirror is not very easy to make especially if you are grinding your first one. Therefore I decided to make a F6 mirror instead of F4.

Astronomical Telescope Overview - al coat

For six inch mirrors the radius of curvature could be 90 inches (F7.5). For a 12 inch mirror this distance could be 150 inches (F6.25). Since the rest of the telescope will be built later these numbers for mirror radius need not be exact. Materials Mirror grinding kits are available from various sources.
