UV Lightbox Questions

What are the over all dimensions of a box that size, Sandy? Damn thing has to be really freaking big, if I am visualizing it right.

Mark,

Yes, it is pretty big, say about 51" X 29" X 9.5" and probably weighs around 50-60 lbs. I use it over a NuArc vacuum frame that is 44"X33". The NuArc frame is on rollers, so to place the negative in the frame I roll it out, load the negative and sensitized material, and then roll it back in to expose.

That makes sense in your case.

My interest is to make long panos from stitched digital negs. Pictorico is supposed to be releasing 13 inch OHP in rolls this year and I want to print some images about 36 inches long. I'll look at paper suppliers for sizes. I pretty sure some papers come in 40-42" sheets.

I have seen papers in 40-42" sheets. Also, Rising Stonhenge can be bought in rolls. Vague about the width, but was in the 36-40" range as best I can recall.

Another simple solution for this is to run a bare heavy guage copper wire accross the top of the tubes connected to the ballast(s) ground. I've made three units this way and it works great!

Whether I go with the sheet metal or the bare copper wire, does this need to then be attached to the sockets? My ballasts are grounded and I was going to attach that ground wire into this copper wire for behind the tubes, but I guess my real question is... do the sockets need to be grounded as well?
