DIY Internal Window - Wooden Sliding System

It took me some time to work out how the window pane should slide. First I did it with an aluminium track but somehow it wasn't the right thing. Here is a better solution. This wooden one involves some fiddly work of drilling in acrylic sheet (fitting rollers and handles) but the result is well worth it. It really feels a lot like a real window. Do it yourself and save a lot of money. Here is how it is done.

This solution is obsolete and I later replaced it with a wooden track (see end of article) but I still keep it here just as one of the possibilities, if only for comparison.
