Making a homemade acrylic wedge
I have asked a friend visiting USA to buy Sony Reader for me. It will take quite a few weeks until she returns from her trip.
In the meanwhile I want to prepare for making myself a homemade lightwedge.
I am planning to buy a thick (cca 10mm) piece of acrylic "glass". (That will be a slight problem, because everyone wants to sell me 1.5m x 2m piece and all I need is an A4 sized piece).
First I will cut the acrylic into the desired size + 5mm on each side.
Then I will glue it into a board, using cca 10 mm thick spacer, so it is coplanar with the board and is above the surface of board. I will put a screw to the each corner of the board.
Next I will take a long piece of coarse sandpaper and glue it flat to a large flat surface. Now I take the board and position it above the sandpaper so it stands on four screws with the acrylic touching the sandpaper. Screws will be standing next to the sandpaper and will be able to slide very easily.
Then I will spend some time sliding the board back and forth so the acrilic grinds in the sandpaper. By adjusting the screws I will be able to make precise wedge.
When the wedge is done I will use finer and finer sandpaper. The final grinding will be made with a sandpaper used for finishing automobile paint on a rubber block.
I will finish the surface using polishing paste. You can get amazing results with polishing paste on acrylic.
I have been working with acrylic before and it can be grinded very well and very rapidly. By polishing it you can make it look very, very nice and proffesianally made. Acrylic can be also bent and formed when you heat it very carefully. Be prepared to waste a lot of material until you get it right.

If you have no experience working with wood and/or acrylic and if you value your time at more than 2 bucks per hour you will be much better off buying the original LightWedge and trimming it to your needs. But FIRST PRACTICE ON A PIECE OF ACRYLIC YOU ARE WILLING TO THROW AWAY. Acrylic has peculiar properties then you try to saw through it.

I have no means to purchase Lightwedge
Even purchasing Sony Reader is very complicated for me.

An average salary in my country is magnitude less then in USA. (so I consider $25 to have much greater value than most of you)
I will do this project when I get Sony Reader into my hands, so I can make a perfect fit. I will post photos of all steps, but do not hold your breath ...
