Mirror making - how to remove central hole?

Posted By William Cheng

Do some of the work with the TOT. TOT will "remove" the edge of the mirror. Which is what you want since you have a hole. This might speed up the process. Good luck. Secret of mirror making is to stay with it. Bill

If you really worry about that then it won't hurt if you rotate your scope in every possible combonation of positions every few hours and if you are really worry then every few minutes. 8) Bill

Ya Kno Wat Bugs Me?

Posted By William Cheng

Seem to me a bunch of finger pointing to me. I say look into the mirror. I see people drive to their mailbox, 3 heat pumps, 5 cars, 6 bedrooms with 3 people. Take 3 showers a day. Throw half of the food away. Every lights in and out of the house is on. Everyone have the Xmas lights all lite up.Yet some how GW and the big business is to blame.
I been to SPSP at Australia, there they bring their own plates and forks to the vendor so they don't have to use paper. Do we do this here. No way hose A. We are Americans. We live it up and blame others. So, want to help and save yourself from destruction??? Turn off the lights and move into a smaller house and put on a sweat shirt. Shut up and do something to help.

If I'm spending your money, I look for the most expensive 6F8 I can find. If I'm spending my money, XT6 from Orion.
