Re: A Besseler 23C II makes an OUTSTANDING copy stand!

You can get a nice old enlarger for under $50, and most can easily have the head removed to function as a copy stand. Admittedly, that's NOT the case for my Beseler 23CII -- not cost not easy head removal…
Odd, what is it that seems difficult?
The head comes off the Besseler 23CII with just one "C" clip retaining ring. Then slide the pivot pin out, and the head is free.
Next, construct a box that is 6 5/8th" by 6" by 6" or so. The only critical dimension is the 6 5/8", which is the width of the existing head mount. Ideally, this could be aluminum, but even thin plywood would work fine. Even the 6 5/8" isn't critical, if you don't mind some side-to-side slop, or can put some washers or spacers on the pivot pin.
Next, drill a hole through both ends of the box along one edge, so the pivot pin can slide through and re-attach the box to the base.
Next, you'll need to attach something to the bottom of the box that will offset it the proper amount from the tilted column. You can use a drywall or builders square to determine the amount. Look at how the enlarging head does it, and cut an appropriate bit of aluminum or thin plywood. You can either cut and trim precisely to make the box perpendicular with the base, or do like Besseler did, and make a little adjuster with any handy fine-pitch screw.
Finally, put your favourite quick release on the side of the box facing you. Ta da!
I bought one of these converted 23CII copy stands at a photo swap meet. Correction, I looked at it several times during the swap meet, and at closing time, the guy gave it to me, on condition that I take another enlarger away with it. It had an obviously custom-constructed aluminum box that, instead of hanging off the pivot pin, was machined with the proper slope to attach with bolts directly to the movable part of the stand.
For more versatility, make your box taller by about 4"-5", and tilt it back on the pivot pin until it hits the latch that makes the enlarging head able to project on a wall, for huge prints. Cut the appropriate slot, and you can use your copy stand to shoot huge artwork on a nearby wall!
Yea, I'd say the Besseler 23CII is one of the easier and more versatile conversions to do — at least for the superior tilted-column design. That's why I sought one out for my yet-to-be completed conversion… I'll put some plans here when I get it done.
So little time, so many projects…
