im not following... thats the lens board or the lens stage where the lens board mounts to?
you mentioned it cant be removed, because its casted in or riveted?
can you remove the lens n its lens board n take a picture top down? whats tye underside look like?
I'm interested to see what you come up with.
I recently got my XL up and running. It's a nice enlarger, but I noticed this same problem sometimes! I found that angling the negative just right would fix it, but that only works with small prints.
If you look at the schematic it's a little easier to see. The lens stage (part 22) is the metal plate at the bottom that the bellows attaches to and has a large off center hole. Below this attaches the lens board adapter (part 133). This is what I am holding in my hand from the picture I posted earlier this morning. It has a square opening and has three attachment points to the lens stage. When the lens adapter is screwed in place (and there is only one way to attach it) the square opening of the lens board adapter is eclipsed by the off center hole of the lens stage (which you can see in the pictures from my OP). If I remove the lens stage (part 22) then there is nothing for the bellows to attach to or for my lens board adapter to attach to. If the lens board adapter is flipped 180 then there is no overlap but there is no way to attach the lens board adapter to the lens board.
None of this makes sense to me. Why would you have an off center hole for the lens stage? I've owned multiple enlargers in my life and I don't recall ever seeing a design like this. Why would the lens board adapter have a partial obstruction in the mounted position and a clear opening in a position it's not possible to mount it in?
i tried looking for a manual but cant find anything.
cut that thing!
the part you are talking about is also found on MXT enlargers it has to do with the 3 lens adapter , i have 2 mxt 's one has it the other doesn't it is not a defect
Don't worry, you don't have to cut it, just in one orientation the hole is way off center, lens fits, and works fine...

As mentioned above, that opening is off center for the lens turret. Not shown in your diagram above (#110 on this diagram)
OH WAIT... thats the plate for a turret. It has to black out 2 lenses so the one selected is the only lens being lit.
That explains it!
dont cut it. the center of the lens in use should be the center of the light path.
I don't have the turret but you're correct that is where it would be
IC-racer: I can see why the may have designed that offset for that purpose (lens turret) but I don't have one of those. Even if I did the vignetting would still be there?
For those of you who have a 45V XL can you tell me what your part number is for the Lens Board Adapter? Mine is 10-49524. You can see where the number is listed below
