[ATM] Manufacture lens

["chico-astron" <chico-astron@bol.com.br>]

                       Hello!  I am Francisco Jose Hisses, (Chico) president of the CENARA (Centro of Astronomy of the Region of Araçatuba city)estado of São Paulo, Brazil. I finished to construct to a small laboratory for manufacture of lenses and mirrors for telescope reflecting refratores and telescopes.  As still I am developing a vacuum chamber I myself power to aluminize my proper mirrors, for the time being, to initiate the training, I am starting to practise production of lenses. 
                       I am initiating with simple lenses (plan-convex) and already I am having some progress.  But I want to start to manufacture biconvex lenses, (that they allow a lesser effect of chromatic aberration) and later will confection dubletos, but for this, necessary to obtain information of as I can work with lenses of this format without that the opposing curves are out of alignment between them (in still necessary form of wedge ) e to know which the tools that I must use in this process. 
                        You could help or indicate some Site me where I could get this type of orientation? 
                        Debtor.
