Hey Dave, When I built my aerocap a few years back I made full sized drawings printed on large format printers at Kinkos and a local blueprint/drafting type shop. They were relatively cheap.
The drawings were based on MS Word Draw images which I converted to PDF files at 1/10th scale. When they printed them, they chose a 10X print size and Voila. The final product ended up within 1/8th inch over the largest part which was sure close enough for my world.
Here's what I had printed.
Based on this side view.
It looked like this.
*Note: These were made before I had learned about the template, so the final product was sloped too steep. It still worked OK.
Here is the last picture I took of it.
