    I have a bessler 23c and I need a lens board with a smaller lens opening. I have one that fits my 50mm shcneider which I believe has a 39mm jam nut. My new to me Schneider 100mm does not fit at all, the opening is way to big. I'm not exactly sure what size but I'm sure someone here will have an idea! Let me know what you got.

    Note that the lensboards for the 23C variations and the Beseler 45 enlargers are the same 4"x4" boards. Later ones have a plexiglass "lightpipe" to illuminate the lens f-stop setting, early ones do not.

    I'm pretty sure they are/were made with a 25mm mount. If looking on ebay, sometimes is cheaper to buy a board with inexpensive lens than just the board.

    Enlarging lenses (though I don't know about Schneiders) were also made in a 32mm mount; I assume you've verified that yours are 25 and not 32.

    I have a lens board sopmewhere with no hole, just a center mark. But if you are using a 39 n need to change lenses.. use the adapter!

    Or make one from 1/8" aircraft ply from the local craft/hobby shop.

    Well I did measure it, but I don't have any good calipers and just have some crappy measuring tape, looks like I got it wrong! If anyone has a 32.5 mm lens board or a 32.5 to 39mm adapter it would be great!

    I got an undrilled board, just a pilot hole in the middle, and a board with a 30mm hole, at least that's what it measures with a ruler, can't find by calibers. Both have the plexiglass light pipe.

    I guess i could achieve the same result by just drilling out the one I have slightly, though I'd need a pretty bug bit!

    Drilling a larger hole is difficult without special tools as you don't have the ability to utilize a pilot bit. It might be more feasible to file it out.

    But unless your lens or r-brian's board is non-standard (i.e. 30 and not 32) they probably match.

    I'm about to traveling for a big so I just went ahead and ordered the back ordered adapter to make the 39mm work for 32.5mm from BH. Should get to me in about five weeks or so. Thanks everyone for all your help getting this sorted out!
