I want to buy a Carey mask... how can I get one?
Nobody is making these commercially. If you have access to a laser cutter, here is a DXF file that you can scale to suit your scope. http://www.btinternet.com/~gfcarey/masks/CareyMask.dxf
I am still trying to find the ideal material for the masks. Black perpex is unavailable less than 3mm thick, and the mask ideally should be much thinner. I ordered a range of clear perspex today from 0.25 to 1.5mm thickness and will experiment with cutting a mask and then spray painting black. When I have found the best material I would be happy to send a few to people to try out. (The one I use is cut from 1.9mm mounting card and works well, but it is a bit fragile).
