I made some alloy strips from 1.2 alloy sheet and shrunk them to shape the first un-drilled one i shrank too far and is useless three attempts later I managed to have two good ones.
they will look a bit like this when finished
I found some alloy effect edging but it wouldn't bend around the curve at the rear top of the perspex so I had to angle them like this.
Not sure if its better or worst any opinions?
