SAC, Here's a correction about Paul Lind's Mirror Grinding/Polishing Machine. Something bugged me about a statement that I made at last Friday's SAC meeting. I mentioned that I was "excited to see this machine in action" since the time I first saw it when Paul "bought it". Well, Paul "built" this machine, see the link below for a story in the January 2002 edition of Sacnews. See pages 3 & 8. http://www.saguaroastro.org/content/SACNEWS/sac2002/sn0102.pdf On page 3 is the following quote from Rick Tejera: "We got to see how to use the tool to grind the curve into the glass, both the old fashioned manual way, and using the machine Paul made to automate the process." So, Paul, I apologize for the error I made at last Friday's SAC meeting during the Show 'n Tell presentation on the "Pouring of a pitch lap..." I was thinking of the other polishing machine that you had purchased at a SAC meeting swap meet, the one that is sitting on the shelf in your shop next to the drill press. Oops. Rick R. SAC
