Having used Araldite glue to stick a styrene strip round a chemiwood base, I found this went too lumpy and would not hold the curve of the styrene as I wanted. A better method proved to be the use of contact surface adhesive, which I secured in place with masking tape. This adhesive also worked to stick back sprayed acrylic to the baseboard without eating away the paint. Much of my time this week was dedicated to sanding and spraying the concrete pieces of the model with the support beam requiring several coats of sand sealer to make the wood appear smooth without a grain showing through the paint.
As a group we have come up with a rough time plan of our remaining tasks to complete. This includes working out how to make our brass mesh order fit around the top strip of flooring. So far I have cut this to waste as little as possible and I have used 3mm high blokes to raise up the "metal" paneling to the correct height.

Me and Paul were interested to see if we could cut out the walkway's support beams on the CNC machine as they are not in fact flat but T-bar shaped. However, once our drawings were converted into Excalibur the closed lines no longer joined up and overlapped ever so slightly. This meant that when the machine was asked to show a tool path, the path was all over the place, missing out parts and cutting inaccurately. We now have a choice to try and make the drawings work for this software or to stick to the original plan of laser cutting.
