Step 1: Materials
1 piece of translucent white plastic, from the San Francisco Tap plastics scrap bin, 5 bucks,
1 clip board clip from tap plastics 1 buck
1 1x3 from home depot 3 bucks
1 sheet of back board from home depot, 2 bucks
1 light from home depot 7 bucks,
4 brackets form home depot 1 buck
Some aluminum foil, wood glue, 3m spay mount staples and rivets, already had. durham wood putty.
Step 2: Step 1
take your 1x3 and cut your board in the proper lengths, using 45 degree miter cuts on each end. This is just like building a frame.
Step 3: Step 2
now take your 4 lengths of wood, and cut in a groove. I used a little hobby table saw i picked up at harbor freight. Make sure the blade only comes to the width of the plastic sheet, and clamp on a guide making sure the space between the blade and the guide is the width of the plastic sheet. groove the wood so that you're cutting out a corner in each piece.
