    WD-40 is not a good lubricant. Neither is vegetable oil. Both will gum up with age.

    Any suggestions? The vegetable oil was more of a temporary thing anyway...

    A very small amount of white grease, removing all except what is in play. However, I ponder if this point was ever meant to be lubricated. There is a good chance that it was simply frozen from disuse, and now that it is free, could be cleaned up and would present no further problem with regular exercise.

    @JBrunner - I'm pretty sure the cam (arm) wasn't meant to be lubricated since the others weren't. However, the cam didn't seem to want to loosen up after repeated back-and-forth motions and there doesn't seem to be an easy way to loosen it otherwise, so I figured a little bit of lubricant should help.

    A little lub never hurt anything. Any house hold lub.
    Apply some fraction of a drop by use of a tooth pick.
    A quart of non-detergent 30 or 40 weight is good
    to have on hand. Dan

    I solve this black paper dilemma at least once per week in the college darkroom. Most times a student puts a sheet of paper in the easel either while the enlarger light is being projected or when they are focusing the image on the paper. Then they turn the enlarger off and give it the brief test exposures. The prints have white borders where the easel masked the paper but the rest is black. I don't know if that is what you are doing, but I see it enough to mention just in case.
