What are you using for an enlarging lens, and what are your typical enlargement sizes and exposure times?

Politically, aerodynamically, and fashionably incorrect.
Right now I am using taking lenses on both the 4x5 and 5x7. On the 5x7 I use a Fujinon 250mm, as I have one mounted on the correct board. I have not done anything larger than 8x10 using the incandescent bulb, but if anything it is too bright, as I was getting times of about 6 seconds at f11 for a normal print without filters on the 4x5. On the 5x7 60w may be more reasonable. I have not printed anything yet, but on the easel the image looks pretty bright.
Very interesting! Thanks for the information. I would be interested in your results from making a print, particularly in how even the light is.

Rick changed the name of this thread for me today. People had been asking me about it, as it was hard to find in searches with the title "5x7 enlarger", so I asked him to add "DIY" and "homemade" to the title. Hopefully it will be easier to find now.
Thanks Rick!
I found it!
This is an interesting project. Do you have any prints you can show us?
I intend to do something similar for an 8x10 camera I'm building, but I was thinking horizontal as I don't have the right situation to mount the result to the wall. I've been thinking of repurposing an LED array kitchen/hall light I saw at a hardware store, thus getting around heat issues. I've been thinking masonite for holding negatives and using taking lenses for enlarging and/or projector lenses (one of which I've taken pictures with on Xray and expired 8x10 film).
Sounds like that should work. I also used masonite for negative holders. Good luck!
