Little update on the last stages.
Was thinking of using thick card for the monitor surround,and following the 2dollar guide.
But nicked an idea from Bobby about using foam board.
I bought 10 sheets of A3 5mm thick black foamboard for 20 euros.
First off the main problem was it was black...I thought that would bypass the need for painting,but it just made marking out and general visuals problematic.
A brand new sharp blade is essential,and I eventually found out you can actually sand this stuff,I used 220 grit and shaped my first prototype into a pretty good go.:
So the last pic Ive applied a bit of filler into the corner joints.Im thinking this trial piece could be the finished article.
