I got this idea because of the terrible smell casting acrylic causes.
I happen to have and acrylic box the perfect size and then took a trip to the Science Surplus Store. I got a 18 volt fan and cut a hole in the back of the box. Over this I placed a rectangular plastic cone type object and drilled a hole in it to fit some old vaccume cleaner hose. The hose runs up the wall and is connected to the fume exaust fan that my husband put in for me. All this is is a bathroom exaust fan vented to the outside. I have also run into the problem of it being too cold in the workroom for the acrylic to set well so I solved this with a clip on desk lamp. I used an old airline tray and cut it to fit into the box. I can slid it out part of the way when mixing the acrylic and when mixed I slide it back in and close the lid. The entire time while mixing I had the fan in the back of the box and the ceiling exaust fan on. I still had on a vapor mast but the smell was decreased at 75 to 80% while mixing and even more durning the drying stage while the lid is closed. I made sure to put all of the mixing cups and anything that had the acrylic on it in a seperate plastic bag form my usual garbage and that was taken out to the garage right away.
My son always complains that the smell comes right up through the furnace vent into his room but when using this he didn't even know I was doing any casting!
