How long is your warmup for the 2 minutes burn time?
My home made Vacuum Exposure Unit
32
I just finish building my exposure unit today. I thought I would post some pics for you guys.
It is 46H x 37.5W x 29.5D. the glass is 28x36 1/4" tempered.The lamp is a 400w MH. It has Dayton 263cfm blower, and uses a Gast vacuum pump. A neoprene vacuum blanket. I have 3 switches mounted on the right side. 1 for the lamp, 1 for the blower, and 1 for the vacuum pump. the shutter is a Manuel design it slides out the front just a few inches below the glass. I burnt a few screens. looks like 2 mins does the trick. This is a big step up form the 500w halogen. that took 23min. what do you think?

Thank you! 
I am not to sure how strong it is. It does not say on it, and I bought it used. I would say it is kinda strong. It is intended to evacuate a/c lines, it draws 4.2 amps. Probably a over kill, but I only paid $20 for it on ebay.

the lid is pretty easy. i would have liked to have the neoprene on the bottom of my lid, but i did not design the bottom with a location for the vacuum hose. this would have allowed me to use the neoprene its self for the gasket, but i desined it to have the hose mounted in the lid.
what you will need is to build a frame, figure out what side you want the neoprene on. if it is on the top like mine you will need a gasket between the lid, and the bottom.
after you build the frame. attach the neoprene to the lid using Gorilla Glue. follow the directions. this stuff works! make sure you clamp it or use a weight to apply pressure while it dries.
when you attach the hinges. screw them to the bottom first. when you go to screw them to the lid. apply pressure to the lid. to preload the hinges. this will insure that when the lid is closed it is putting pressure on the gasket. do the same when you attach the latches in front. make sure that when the latch is closed it is pulling the lid down into the gasket.
hope this helps you
Thank you
No, neither will fit inside 5". The pump is 8"x8"x6". The blower is over 10" tall. You can mount both out side of the enclosure. the pump would be just fine sitting in the floor. The blower can be mounted to the side blowing into the enclosure. It only needs a 4"x4" opening. you would just need a large opening on the other side to vent out the hot air. I would say 4x6 at least.
