I have wanted a lightbox for years, I live in a small flat and don't have the space to store a large lightbox. I decided to build a photo/tracing lightbox into my Ikea coffee table. I picked up all of the equipment on ebay and put the whole lot together in a couple of hours. The table is an Ikea 'Lack' and cost about £5, they come in many different colours.
Step 1: Choosing Correct Acrylic
-Ideally I would have made the top from one single thick sheet of acrylic with a routed out step around it's edge. However to do this I would need a router and a acrylic cutting router head... which I don't have. Instead I ordered two sheets of Acrylic. One 8mm thick transparent sheet and one 3mm thick Opal coloured sheet. I had the clear sheet cut slightly smaller (which the acrylic company did free of charge).
-Lack table top measures 550x550mm
-Clear Acrylic 8mm 480x480mm
-Opal 3mm Acrylic 500x500mm
-I purchased these materials on Ebay from trentplastics.co.uk, they gave me cheap combined postage and next day delivery.
