New user wants to "roll his own". I found this site after several hours searching for the right parts sources. I want to build a 12 inch "skeleton" dobsonian. I could also see building a tube style rig. It seems like one of the advantages of the skeleton unit is its construction makes it best suited to being kept outside. I want to grind my mirror as a means to save money. I think I can get glass from a local glass store. I watched the Dobson video. How have you gotten it done? What did you use to get the grinding and polishing done? Since this is my first build, I am looking to avoid reinventing the wheel. I would rather borrow yours and adapt it as needed. Lessons learned and how you would advise yourself knowing what you know now are welcome,no, coveted. The inspiration is to expand my granddaughters' apprehension of God's Creation. I think once they see Jupiter's rings or the craters of the Moon, they will nevelr look at a night sky the same way. Thank you for any help you can provide.
