i would like to find more detailed information about casting blanks,books or web sites which have detailed descriptions of casting process,
annealing, furnace design,mold materials,etc.
i have wanted to try casting blanks for a long time,and believe this is the only way to save $
building large telescopes,casting a 25" blank for
under $500 is my goal.
i have the $ and the time,just need more information.
