One more time: UV Light boxes
I've looked at the archives for this and ran into a lot of questions and some dead links. The free plans on www.eepjon.com that were so popular seem to have gone away and I could no longer find similar info on Photographer's Formulary.
So, since this is a popular topic, anyone up for writing an article on making UV light boxes? The one on unblinkingeye is an excellent resource, but frankly I'm looking for something that will tell me more or less exactly how to make a generic 11x14 box as I don't have time for the design phase. Having said that, I will be glad to jot down a quick article about whatever I wind up doing and post it to serve as a boiler plate for others to add to.
I guess truthfully, it's neither the box itself, nor the wiring that put me off, but the cost & time required for what seems an otherwise simple project.
TheFlyingCamera had an idea that seems very attractive - buying existing 2-bulb fixtures and putting 6 of them together. Since the largest neg I'm likely to deal with is 8x10, this sounds good - any drawbacks?

I bought one of the Edwards Engineered Products UV light box kits -- waste of money, actually. Fortunately it was the university's money, not my own. The boards were not cut to the right size, venting slits and the hole for the fan were not pre-cut like they were suppose to be, and instructions were written by an engineer not familar with the effective use of language (which is still better than instructions written by an English major with no knowledge of engineering!LOL!)
I also made the false assumption that I was buying one of their pre-made lightboxes, but in kit form. Instead it was a lesser unit, based on the do-it-yourself plans they use to have on the site.
EEP did offer to replace the boards that they failed to pre-cut the holes in, but I was under a deadline to get it together for an Alt photo class, so I winged that part and managed to put it together with the mis-sized boards anyway. I have to take it apart to find a bad connection -- one of the tubes does not fully light...perhaps it is not grounded properly.
The advantage of the design is that it uses seperate balences, instead of fixtures. The tubes are closer together than if one uses fixtures...but it does require a lot more wiring. Having the tubes closer together can give you more UV, and a more even exposure with the printing frame closer to the tubes.
But the pre-wired fixtures work fine, too. If you think you'd ever want to expose more than one 8x10 at a time, you might consider buildine a longer box using longer fixtures. When I use pyro developed negs, my exposure times are rather long (30 min+) -- and being able to expose two negs at the same time helps to keep the work-flow moving along quickly.
