May sound like a stupid question,But I am not a machinist.How do you accurately mount 2Z rails and 4 blocks to the Y which has 2 rails and 4 blocks also.Could be a nightmare for a non machinist.Any tips or tricks?Is a cheap drill press good enough?One tip I read was to down load 1 to 1 drawings say from THK,print actual size and use as a template.Perhaps using a machine shop is the answer.
