Could be worse. Could be a glue argument.
For what it's worth, I was shown the method in that video at a large club launch about 10 years ago by one of the hobby's Old Royalty—one of those guys who took part in record altitude flights and had a job in aerospace. He took a similarly brusque attitude with me and grabbed my chute and showed me "how to do it properly." The main point he made at the time was to use the shroud lines to help do the work of opening the chute for a small rocket in which the chute really needed to be kept compact.
I don't claim to be an expert on chute folding. I do get lots of requests for videos and techniques, which when I have them I'm happy to share. A number of you have videos on the Jolly Logic site in the flights section, but I'm happy to also post your How To videos as well. Always welcome!
Things can vary greatly depending on your rocket and your chute, but there are a few things that I do believe are always important, most of which you'll see in the User Guide of Chute Release:
- I've seen "puffy bundles" fail to deploy because they trap the band—avoid that
- Since shroud lines are no longer needed to hold a bundle tight, put them inside to protect them
- Flame blankets should be tethered in such a way that they get whisked away when the shock line goes taut
- Never tether Chute Release in such a way that it gets yanked when the shock cord goes tight—the tether is just there to support the weight of Chute Release after release so that you don't lose it (the 300# kevlar line it ships with is massive overkill)
- If you are folding your chute the way you did before you started using Chute Release (or a cable cutter), you can do better
- Make sure your shrouds cannot just slide out of your bundle before release (from the flap or the from the center)
- The goal is to create a bundle you can't shake loose by hand ("shake test") but which just falls apart after release ("release test")
- Make sure your bundle will eject easily ("puff test" from the engine mount)
Anyway, send me a video. Happy to post it.
