Thanks chaps,
Your advice is greatly appreciated. Without the strut option I think I would have given up by now!
Little more done. I’ve finished the slats and I’m actually pleased with the finished result for once!
I copied this picture loosely...

To end up with this...

And now all ready for some paint (I think). First coat of what I hope looks like painted aluminium dope...

Came out a little rough for some reason, so a bit of a rub down required.
