The harness risers were made from wide shoe laces and small rings sewn on using waxed dental floss. The test chute was packed and put into the container. Of course, I had to learn how to pack a round parachute as well... -

Google to the rescue and I found a method to divide a circle into 14 equal parts, adding some for the overlaps. A card template was made and the gores cut to size I used the grouting lines on my tiled floor as straight edges The gores are laid out and taped together. There needs to be an overlap at each join, which creates a pocket, or sleeve, through which the lines are threaded. The lines are pulled through the gores. One line goes right through from one side, through the top and is the same line on the opposite side. The lines are knotted at the top, where the pilot chute will be attached later. The first test parachute is ready for testing. -

In the meantime, I was also making a test parachute. This was simply made from refuse bags which were taped together. Regular string was used for the lines, a weight attached and taken for a test from from a suitable plane. This demonstrated that the concept was good and work on the model continued. The first problem was that the pattern for the gores (parachute panels) did not work out correctly. -

The following series of pictures will hopefully explain the procedure. This whole design is over complex imo. When the pin is pulled, the elastIc bands are supposed to pull the two container sides open. I found this to not work reliably. Important to note also, is that the container size was hopelessly too small as per plan. The first test parachute would fit but subsequent ones, made from thicker material, would not. -

The backing plate was cut from 2 or 3mm ply and some ply reinforcing was glued to the sides as the hooks and rings would be attached to these. I used contact adhesive here. Edited By Torsten Spitzner on 08/09/2020 08:26:07 -

The 'take a snapshot' function is most useful, I use it regularly to print small parts of plans. Small hooks and rings were made up from piano wire and the container cut as per plan from suitable material. -

The next series of pictures relate to the container construction. ( the container holds the parachute), as per plan. Ultimately, I abandoned this entire method and made something much simpler. I couldn't get the designed container to open reliably. So I'll post the original idea just for continuity.
