  • So when you buy this stuff do you have to listen to a sales pitch? .... Sorry. Say, where do I BUY some pitch?

  • Hi Gordon,

    Great videos and great ideas. If you are interested I have my machine setup for auto dripping CeO while polishing and also use a teflon sheet under the mirror to have it automatically rotate while polishing. Right now I am doing a 14"/23mm borofloat blank and have no problems with astigmatism whatsoever. My videos are on Betube4.

    Regards
