Answer 1

Newport glass sells kits:

There's a copy of Roger Ceragioli's old refractor-making article here: http://www.fortunecity.com/marina/manatee/1879/refractor/Refrindex.htm

This is a project for experienced glasspushers only!

Aluminizing a mirror requires a vacuum pump and chamber, plus a means of vaporizing the aluminum. Certainly not cost-effective if you're only doing a few mirrors. If you Google around or check old telescope-making books you should be able to find instructions on chemical silvering processes. Note that some of those processes are potentially dangerous.

Answer 2

Making an achromatic lens for a refractor is something only the most advanced amateur telescope makers would attempt, after many years of mirror making. A much more manageable project would be to make the mirror for a reflecting telescope. There are many books and kits available to do this.

Answer 3

If you have to ask here, you won't be able to ,manufacture your own achromatic lens. If you want to coat your lens you will need a France to vaporize aluminum (foil works) and a pre-figured blank for the mirror

Answer 4

Usually people grind the lens themselves and then send it out to have it aluminized. That's what my dad does.
