I made my UV box with these instructions off the net and sourced all the materials for about $250. The ballasts were the expensive part and I was able to get the bulbs for about $4 ea. I have a wood worker cousin who helped with the box, but the whole thing works very well and I get about 5 minute exposures with my gum prints and can print up to a 16x20.HI Ken,
Thank you so much for the offer. I was able to find a cached one on the internet. I think I should provided a link here for those interested.
