Well I managed to drop / scratch the marquee acrylic (on both sides). I did mistakenly order 3 pieces so all good.
I've been itching to see what this looks like so balanced the marquee on top of the mid section - it has some pads placed temporarily underneath the unpainted piece to it's higher than it should be. Pleased with how this is turning out ....
I want to get the filling and painting on the spacer between the 2 sections started today.
I've managed to drill the holes in the CP and check that everything lines up. I need to trim a couple of mm off the side panels and then I can glue and screw them into place before sanding it down and filling it.
You can see the chamfered sections to act as guides to make slotting this in as easy as possible. The middle chamfered piece has a threaded insert to allow the panel to be attached to the base section.
I've left about 1mm around the perimeter of the acrylic to allow for the layers of paint.
