    Forgive the ignorant question... but where, exactly, is this site? I've seen a number of people mention it but I can't find it with google searches.

    I think the Edwards Engineering UV box is just what I am looking for. If understand what I am seeing correctly, I believe an 8x10 Photographer's Formulary printing frame will fit right underneath an 11x14 basic UV unit.

    Thanks for all the posts. I'd build it myself, but with no time to make prints, I definitely have no time build one.

    I think Edward's just made a sale. For $600, I guess that's pretty good deal. Yikes!

    The NuArc 26-1k is a great printer, and at $300-500 a great bargin. I have one and use it a lot.

    However, in all honesty I have to say that I prefer my bank of UV tubes, which consists of twelve (12) 48" BLB tubes over a 48X38" NuArc vacuum frame. It prints just as fast as the NuArc 26-1k, but with more even illuminaiton over the whole frame. The light integrator I use with this unit, an Olex Ai 970, is also more accurate than that of my NuArc 26-1k, espeically with long exposures.

    Total cost of the 48" bank. About $400, broken down as follows: $250 for the parts and materials for the UV bank, about $100 for the big vacuum frame, and $50 for the Olex Ai 970 on ebay.

    Time of construction of the UV bank was about 2.5 hours. I started on a Friday afternoon, and was printing with it around noon on Saturday. Course, this was the second unit I built, so I understood fairly well all of the construction issues from the start.

    Biggest problem. Carting all of this stuff up to my third floor work room.

    BTW, BL tubes print faster than BLB, but not by much. I will probably replace my BLB tubes with BLs in a year or so, but the BLBs do have some advantages, primarily the fact that the light causes things such as dirt, hair, and other particles on the glass to really stand out, which facilitates cleaning.

    I'd recommend you look for an old graphic arts plateburner instead if you have the space. You may be able to get something like a used NuArc 26-1K with vacuum for $250 or maybe less, like free, on a good day. Check with local print shops who may be tossing them. The plateburner is faster and gives superior results for most processes IMO.

    So that's why I like my BLB bulbs Would agree with Sandy about the 48 inch, if I had room would have gone that route. Question for Sandy, is there a way to measure the output (ie a UV light meter), and is it really needed?

    Art, do not think you will be unhappy with the EE UV box, and the good thing is they will take it back in trade for a bigger one - but I would consider how big a print you think you will make, and go one size larger at least...your mileage may vary though.

    OK, I checked out other avenues for UV lights and came up with this: Elation UV Wash

    I think it's perfect for my 4x5 negs. Has anyone tried this UV lamp? I found several sellers listing this at $150. Beats $600 anyday if it does the job. Plus it's 50lbs lighter!

    Yes, you can measure the UV ouput with many exposure meters. However, to get an idea of the radiation over time, and at different times of the day, you will need to take many measurments, and perhaps average them.

    Best thing is to connnect your bank of UV tubes to an integrator. However, even if you don't have an integrator the output is fairly stable.

    I, too, just finished building a unit based on the Edwards Engineering plans. When all was said and done, it may have been cheaper to actually purchase the kit from Edwards and assemble it myself but I have to say I did have a lot of fun building it from scratch. The only major hurdle for me was having the wood cut to size (since I don't have a saw of any kind). Luckily, the folks at Lowe's were more than willing to help.

    Overall, building the box was an enjoyable experience. Now I just have to make some negatives so I can use it!

    Art- if you want to try the really cheap method, and aren't going to initially print bigger than 11x14, Home Depot sells BLB fluorescent fixtures for about $17-20 each. They're made by GE - ballast, BLB bulb, housing all included. I bought six of them, and I screwed them to the bottom of an IKEA shelf that supports my regular 4x5 enlarger. If you put the housings tight together, you get about 1 1/2" to 1 3/4" spacing between bulb centers. I get very consistent results from it, with base exposure times in the 7 1/2 minute range. I don't have model numbers for the GE unit, but they had them in the store where they keep the under-cabinet fluorescent fixtures.
