real difference between the 75mm and the 50mm?

Lenses for most enlargers use the standard Leica thread on the mounting
flange. Of course, Leica don't use it on their cameras anymore. As
others have said, the lensboard for the Beseler can be as simple as a
piece of 1/8 " plywood with a 40 mm hole cut in the middle if you have
the retaining ring. I used to get 1/8" plywood at hobby shops.

1/8" masonite is much easier to obtain anywhere in the "civilized" world
and works just as well.

I just got a second hand enlarger, and I noticed it came with a 75mm
lens, I unscrewed the 50mm one that was loose to begin with (Too loose
to adjust the aperture) and now the 75mm won't screw in. There is a
metal ring in the (?) lens board (?) and it's loose. Nothing snapped,
cracked broke etc. I don't know what to do.

Thanks for reading,

25 mm?

MOST 50mm lenses are intended for 35mm (24x36mm) and will give greater
magnification for a given enlarger height than a 75mm lens.

MOST 75mm lenses are intended for 6x6 negatives (60x60mm) and will give less
magnification for any given enlarger height, usually not an issue since you
are using a larger negative.
