The straight edge parts of the frame were cut out roughly from the the paper plans and tacked on to the styrene with repositionable glue.

The plans were then scored with a very sharp knife with Skye taking the photos and waiting to laugh should I cut myself. (By cutting the plans out first should mean that wastage is kept to a minimum and if any bits go wrong then I have some spare.) The plans were left on the plastic so that I knew what they were when the build actually starts.

The next stage was to work out how to cut the circular parts of the frame. Some people have made a table to use a router, others have used a circle cutter for paper. After thinking a bit, I remembered that I have a device my father made for marking circles on sheet metal. A search of the garage and there it was big enough to mark the styrene and sharp enough to score. I have found that a cut with the knife will help but at least the scoring is deep enough for the blade not to go of course.
