This book scanner uses simple materials and you can make it with ordinary hand tools. An electric drill, a saw and a glue gun are pretty well all you need. It also folds flat. I've put the whole scanner into a medium sized suitcase. Using it, as you'll see on the videos, is very, very light work. Just lift the light weight counter-balanced acrylic platen, turn the page, lower the platen and fire the cameras.
Some people have now made a larger version of the scanner that will scan documents like archive newspapers and ledgers. So it can easily be scaled up for scanning larger sized materials.
The video links on this page will give you an overview of the scanner and how it works.
The plastic tube and fittings I used for this project are plumbing parts called overflow pipe and fittings. You will need push together tubing and fittings.
My tubing is 21.5mm in diameter, but you could use a slightly wider tubing and this might give the scanner slightly more rigidity.
The tubing and fittings are almost black in colour. Black is good, because this does not give unwanted reflections when you are making the scanning images. But if you can't get black, you could use white or grey tubing and spray it with matt black aerosol spray paint.
Ask your tubing supplier which glue to use. The glue I used is very aromatic, and you need an open window. It slightly melts the plastic, and dries very quickly indeed. So if you are at the gluing stage you have to act very fast and make sure everything is straight, because if is isn't it will be impossible to readjust after about 10 seconds! My glue was like a jelly. It came with a brush inside the container, and just required a medium smear of glue round the end of the tube just before pushing it into the L bend or Tee.
But don't glue anything until you have fitted it all together and ensured that everything fits, and nothing needs tweaking. Once it is glued you won't get it apart again.
