Even though it was a bit windy and chilly, we had a good session on Saturday. Charlie, Craig, Jamie and Jay attended. Charlie laminated door skin to construction styrofoam which is the beginnings of a very light top ring for his telescope project. Jamie brought a 10" Celestron newtonian OTA which needs some parts to make a working telescope. We checked it over and found some sources for the parts he will need (spider, secondary holder and secondary as well as sundry small parts). He will need to build a rocker box and altitude bearings to complete the scope. It will be a nice 10" dobsonian when he is finished. I finished hogging out my 21" mirror using the diamond tool method I've described in the astronomy in utah forum. If you don't make it over to that forum, I can summarize that I hogged out the mirror in less than three hours altogether! This is a 21", f4 mirror so the sagitta is around 0.33" (in other words, that is a lot of glass to remove). This is way, way faster than I would have accomplished this task using more conventional means. Sorry John Dobson, glass removal is no longer caveman work!
