New to enlargers here. Just picked up a nice clean used 45MXII and am setting it up.
-The focusing knob is workable but a bit stiff. The set screw to lock position in place is loose so it is not that. How best to smooth the action of the focus knob?
-The guide is missing for setting the negative stage distance from the head as a function of negative size. Can someone provide measurements for the distance from the head to negative carrier when working with 35mm, 6x6cm, and 4x5" negatives?
Thank you very much,
Harlan
