Question about Nikon 7314 Binocular Microscope
I cannot get the stage up high enough to focus under 10X. I think the coarse tension needs to be adjusted but I'm unsure how to do this.
This might be sign of trouble, because the Nylon gears inside might be worn out. I did not noticed a tension ring on Optiphot 1 or 2. The Nikon S and Metaphot from 1960s to 1976 have Nylon gears with tension ring adjustments.
