Hi All. I apologise if this has been discussed but I can't find a reference anywhere.

I am about to replace the mirror in my 12"LightBridge as part of a restoration process. I obviously need to re-secure the mirror to the mirror cell and am hoping to get some advise on suitable methods.

1. Is there a suitable double sided tape to use. I have read a little about using silicon rubber.
2. Is repositioning the mirror back on the cell precisely where the original was as crucial as I assume it is?

I would appreciate any constructing advice.

Thanks in advance.
