Re: [ATM] Argh! How do I fix this?

If you follow Mel Bartels advice that is to move the
lap around when pressing then you will not have a
problem.  

Mel discovered that technique some years ago.  It has
never been talked about much but it does work.  He
uses it also with an oversized lap to good effect.

I also learned to move the lap around during pressing
after I created a checkerboard pattern on the mirror
face that matched the lap pattern from not letting the
plate glass cool after hot pressing.
