Airbrushing
Painting with air brushes requires practice and attention to the surrounding area. Airbrushes tend to emit paint in a fine mist of spray that is sometimes toxic. To protect yourself and the surroundings, use an airbrush in a booth. The booth will protect you from paint particles and help target the paint. Building an airbrush booth is doable with a room, a window and common materials found around the house and at a typical home improvement store.
Instructions
1. Position a card table against a window so that it fits evenly against the window sill. A standard card table is about 30 inches high. If the window is higher than 30 inches, use a few pieces of plywood on top of the table to make it fit flush against the windowsill.
2. Cut and measure the plywood the same dimensions as the square box fan. Build an open-ended box with the four sheets of plywood -- left side, right side, top and bottom. Secure the plywood together using wood screws. Place the finished box onto the card table facing the window.
3. Tape the furnace filter to the front of the square fan with duct tape. Make sure that it covers the entire face of the fan.
4. Insert the fan into the plywood box so that the front of the fan faces the window. Glue the fan to the inside edges of the plywood box. Once the glue dries, place duct tape around the fan and front of the plywood box to ensure a snug fit.
5. Open the window enough so that it aligns with the height of the plywood box. Push the plywood box with the fan/filter flush into the window.
