Step 11 The Mirrors

 
The mirrors came from the mirror of an OHP.

1.- Protect the mirror with some masking tape.

2.- Mark the centre of the mirror and take it to your local glaziers to get it cut. (normally they wont charge for such a small job)

3.- I found a couple of angle metal things, and with some double sided tape I held the mirror to it. (This will be provisional, as once you know the right position of the mirrors you can reinforce it with some hot glue.)

you might wanna make yourself a FS mirror from an ordinary mirror. get a box of "paint remover", spray or spread them across the back side of the mirror (the surface with blue or gray color) then wait for around 15 mins, finally rinse it with tap water, you'll then get your own FS mirror with just a few dollars =]

 It would be better if you can find an optical mirror.

If I'm not mistaken, those mirrors from the OHP are called first surface mirrors.

The light doesn't go through the glass to the reflective surface, so you don't get refractive errors in the reflected image as you would from a normal household mirror.

 I'm not sure how they are called, but they are exactly as you say they are.
