>Well, I have gone back and polished some more, (now total about 6 hours on

>I would enjoy hearing back on what the members think of where the mirror 
>is. Other than in my living room in a container, I am not to sure how it is 
>comming along lol lol  Please send me some feed back and let me know what 
>you think.  I tried to do a foucault test, but I am still figuring out just 
>how to do that.  I get the mirror lit totally, and then tilt my rig and I 
>can cut the mirror in half making one side dark and the other lit, but I 
>dont see any holes or curves or really anything.  The Ronchi rule was 
>printed on my work computer, (has had the snot kicked out of it), on 
>transparencies that I know are not totally clear. So the quality of my rule 
>I question greatly.   I may either break down and buy a rule, or make one 
>with the fishing line.  but that is a project for tomorrow.  I found that I 
>lucked out on the room in which I do my testings in.  It is an inside room 
>(no wall is an outside wall, no windows).  so I closed both doors,  no 
>drafts, no thermals, heating ducts closed to that room.  perfect for 
>testing! that is a plus.
