Hi I am building a 18.75 in Dobsonion, does any one have or know wherer I can get a set of planes for a scope of this size. The planes that I have are for a 8 inch scope. I am also looking for all of the formulas uses when grinding the mirror and building the scope.

Thanks for any Help Larry Shield lshield@scruznet.com
