ATM tested today at lunch!
hello to all,
after reading everyone's responses to my insanity, I went and did a focal
test using the sun, the sun is out here on a temp basis in MA, we borrowed
it from Fresno lol, I did this on 3 different surfaces in 3 different
locations. all came up with the same. the sun focused at 44 1/2 inches, I
then did the flash light test again, 90". So I found that during my
psychotic episode last night believing my focal was over 90" it turns out, I
am just at my target focal. I was shooting for a f/8 f/7 mirror and I am
just between the 2, 6" f/7.4. So I don't have to go back and regrind,
thinking it was at 90" .
I will continue tonight with the 9 micron, and then make a second hydorstone
tool and melt the lap. A question on melting the lap though, can I melt
this in a clean tin can sitting inside of hot water on my stove for a few
hours? kind of like a double boiler for making fudge candy. has anyone
tried this? honestly, my wife would see me to my grave if I used her crock
pot to melt this stuff lol lol
"insanity is a state of mind that fluctuates during mirror making"
thanks again to all, Charles in wilmington
