45MX Bellows Adjustment

I recently bought a Beseler 45MXII enlarger. I am using the condenser head on it. It appears that the guide for different formats (35mm, 6x6, etc) on the upper bellows adjustment is missing. Does anyone have the measurements or some other remedy to my issue? Any advice is appreciated.

Upper bellows goes all the way up for 4x5, and about an inch or two from the top for 6x6. Lower than that in each case will vignette. Hopte that helps.

Here's a shot of mine. Mine says only 45MX on the filter slot cover, but the manual is for a 45MXII, so hopefully it's the same.

Good Morning, Lance,

The indicator shown in the photo provided by Bethe is attached by two screws. You can easily make one from thin metal, plastic, wood, even cardboard. Here are the indicator mark measurements for the different size negatives, all from the LOWER of the two screw holes:

4 x 5--one inch up
3 /14 x 4 1/4--2 3/16" up
2 1/4 x 3 1/4--3 1/4 " up
2 1/4 x 2 1/4--4 1/4" up
35mm--5 3/4" up.

Keep in mind that the precision required here is not very great. Actually, you can enlarge all the smaller sized negatives with the head set at 4 x 5, although that doesn't make greatest use of the enlarger's light intensity. If in doubt, just fudge a bit on the side of a bigger negative.

Konical

Damn this forum is helpful! Thanks for all of the great information.
