6x6 Negative Carrier for Bogen 22A enlarger - DIY?

[Two23]

I now have a small Bogen 22A enlarger. It came with a 35mm carrier, which makes sense I suppose. I read that there was also a 6x6 carrier made. These are difficult to find! I shoot a Rolleiflex far more than I do 35mm, so I'd like to be able to make enlargements. How hard is it to make a 6x6 carrier from something like black foam core etc.?

There are a couple on eBay, but seem overpriced At $60-$70

In College, a lot of us would "fight" over the 6x6 carriers we had as there wasn't one available for each enlarger. My budget fix back then was to make a carrier out of some scrap 8-ply museum mat board.
There also seem to be a lot of sellers offering 3d printed carriers on ebay these days.

The ones on ebay are actually for another model enlarger and are shaped differently. I think I can make a pattern from the 35mm one I have and make one from heavy poster board or something.

Thanks

A guy named BitByBitPhoto down in Texas who makes 3d printed film carriers, you can message him to see if he can custome print one for you.

Here's his site with some of the ones he's made: https://www.bitbybitphoto.com/product-category/negative-carriers/

I've made negative carriers out of carboard/matte board, MDF (usually with a mask fashioned out of something else) and 3D printed. All approaches worked. The ergonomics differed a bit.

The challenge with 6x6 is that it tends to sag a bit. Consider glass at the bottom to prevent this. The other way is an effective tensioning system, but I never even tried DIY-ing such myself. For small(ish) prints, a decently made mask (top & bottom) will hold the film flat enough to not run into problems. For "critical sharpness", glass is the obvious solution.

There are at least two and maybe three different Bogen carrier styles for the 6x6 enlargers. Some are simple two part designs, others are a more complicated with three parts. And some other
"house rebrand" enlargers of that era used the same carriers. Spiratone, Testrite, early Vivitar, etc. are also possible sources. Smaller aperture carriers were also available. I bought several and cut them up to make inserts for M601 Durst (heresy, I know!). Bogen made a Mini635, 22a, and 22b, all 6x6 and all were slightly different. You will also need a 75mm lens, make it easy on yourself and get one with a Leica thread.

Thanks. I've just replaced the Voss 50mm with a first class Rodagon f2.8 50mm. Plan on getting similar quality lens for 6x6. I'm only waiting on my grain focuser at the moment.

What sort of glass? Just regular glass, a very thin piece, or would it have to be ANR?

You only need ANR glass on the top side of a carrier, regular glass is fine for the bottom, it should be good glass. I don't believe glass is really necessary but ANR is not needed unless you want glass for the top and bottom.

Unless you scan TMAX films and Kodak color films. The emulsion on those is so smooth that you get newton rings on that side, too.

Plain window/picture frame glass (float glass) is fine. Just make sure you get a piece without any scratches or blemishes.

I'd try it with plain glass first and if this results in trouble, look out for AN glass.

Yes but this post is about enlarger carriers not film holders for scanners.

Yes, I know. I meant "print", not scan. Newton rings happen when optical printing, too.

Is not hard, the Bogen 22s are good enlargers
I used a cardboard one for a while until I was able to find a 6x6 one that fits on a used camera store
O still use cardboard "wings" for 6x4

Dimensions are (10cm wide, 9cm deep)
If you want I can send yu drawings/pics so that you can 3Dprint one.
