I am thinking of building an 8x10" head for one of my enlargers. Does anyone know where I could find information or plans for building the head? I will probably use it on my Beseler 45V-XL. I would like to build a cold light head but a tungsten light source is not out of the question - I could use cooling fans to draw out heat and it would be a diffusion head - NOT a condenser head. Balancing light temperature to get me in the middle VC contrast range would be no problem.

8x10 heads are SO expensive and, being a very handy person, I think I will build the head myself.

Anyway, if anyone can point me to plans or information that would help me with this project, I would greatly appreciate it.

Thanks, Tom

Huw Evans has built some really cool LED enlarger heads, and seems very free with information. Here's a link:

Tom - You might find this 4X5 color head conversion interesting: http://www.bigshotz.co.nz/projects.html You will probably find worthwhile information in the Cameramakers archive: http://rmp.opusis.com/pipermail/cameramakers/ Also these pages: http://www.philsan.com/8x10_enlarger.htm and http://www.wehmancamera.com/vchead.htm

I believe that the Ansel Adams book "The Print" has information on the 8x10 enlarger that he made from a horizontal copy camera. The head used multiple incandescent bulbs on a dimmer and fan cooling as I recall.

Thanks David. I am familiar with Ansel's horizontal 8x10" enlarger but what I'm thinking about is building an 8x10" head for one of my existing 4x5" enlargers - specifically, a Beseler 45V-XL.

I thought that someone (Alan Ross?) had already done this- and that it had been turned into a product. Even if you don't want to buy it- that head would show how it's done.
