nice job on this exposure unit.can i ask what material did you use to make the "v" shape as well as the slide that covers the light to stop exposure?thanks
acrylic glass depending on the kind that you get can allow 40% more light through. but your major factor is the UV coating that is on 90% of acrylic. (most plexiglass you pick up at home depot, menards, ect.. is acrylic glass)
I'm having a problem finding a ballast for a 1000w metal halide bulb that will work with a 110v or 220v outlet. Also where to purchase it would be very helpful also. Thanks.
i'm getting ready to build a unit just like what you showed. Any new pointers? My biggest concern is what is the distance from the bulb to the glass? I am using 34 x 34 inch screens and a 1,000 watt metal hylide.
I'm curious to know about the math behind the size. I'm trying to build a unit for burning screens 24*20 (with a 30*28" glass) and I know that the distance from bulb to glass is 1.5 x mesh size. But that seems quite high and I'm curious to know where that math comes from. Also, about the angle of your reflectors. Do they need to be 45deg?
why do you have to have a fan to cool the bulb if you will expose the silk screen for less than a minute ? there is got to be a reason.... unless you are burning many screen per hour...
how far is your bulb from the glass with such a large exposure unit?
what type of material is that black cloth? its the same cloth for when you roll back to hide the bulb.
Thanks for sharing. Real inspiration.

Would a cut out instead of a print work the same when it would be exposed? Please let me know, trying to start printing.
