Re: ATM Marking center of mirror

["Albert Highe" <ahighe@ix.netcom.com>]

Several people have mentioned how to find the center. As suggested below,
its best to leave the very center clear for laser collimators. I use one of
those glue-on reinforcing circles that are used to repair the holes in
punched paper. I don't know what they are called. It works great with
regular or laser collimators and looks neat and clean.
