I wanted to spray a finish on the heads of 50 or so screws, but spraying the screws while they were scattered on a drop cloth was yielding spotty results. I took a look around the shop to see what I could cobble together out of available materials to prop up the screws for painting. The rig I came up with took about a minute to assemble.
As shown in the drawing at right, I put a plastic grocery bag over a coffee can, pulled it taut, and ran a strip of tape around it to hold the bag in place. Then I poked the screws through the “drumhead” and sprayed away.Emma Kirk, Corvallis, OR
