[Laser] Cutting and bonding mirrors

[Stan]

Hello The Net:


I salvaged the first surface mirror from my rear projector TV and now
  I want to cut it up into smaller squares to make a corner reflector.

Should I score the plated side or the unplated side to make a cut ?

What glue would be best to bond the pieces together without damaging the 
mirror plating ?


Plan is to make 3 each ~ 10" squares and bond them together
at right angles to each other to make the corner reflector.

Any suggestions or improvements ?
