Cording foot ? I do need to fold this chute down into a space 7.5"x 18" including harness smaller is better. Ive already got the gores cut so 12 it be.
Kind of on the same subject I have some military flare chutes. Not the 60" but the smaller 36". The lines are NOT the greatest because most of the time they are frayed. Who does reasonable repair work for replacing the lines with a better material? I was told Topflight does repairs??
Most people don't realize that 550 cord can be used without the core strands and its much easier to sew, IF you don't need the full rating of the cord (iirc 550 outer is good for 300-375lbs), the inner core strings can be used on other smaller parachute projects. I typically use 95 and 550 para cord on all my chutes. A cording foot isn't necessary with coreless 550 as it lays flat like ribbon, but a cording foot is nice to have for the rest of the time.
can you hear me now?
Has anyone used paracord when making their own parachutes. If not what is good material. Ive used kevlar in the past and that will get expensive. Oh and the paracute is a 12 panel hemisherical 20' chute.
Or you guys could just email TFR and we could sell you a roll of what we have used for years.
70lb test braided nylon used on 9"-15"
125lb test braided nylon used on our 24"-30"
250lb test round braid nylon used on our 36"-120"
750lb test flat braid nylon used on our line of UXT and CF chutes.
I used paracord for my 24 gore 9' chute. Here is the build thread https://www.rocketryforum.com/showthread.php?122017-Build-Thread-9-ft-24-Gore-Semi-Elliptical-Chute
It is quite bulky. If you are making a 20' chute, I'm assuming you have a very heavy rocket, +100 lbs. With only 12 lines, I don't think I would go with the kite cord unless you used a pilot chute and d-bag to control opening and a slider to slow down and reduce the shock of opening.
What type of material are you using? The 1.9 oz ripstop from fabric stores is what I used and it is very bulky compared to the 1.1 or 3/4 oz of true parachute material. If you are using the lighter material you will have more room for larger stronger cords.
The chute I made was only 9' but with the 1.9 oz nylon and 24 shrouds that feed all the way across the top of the chute. It still fits in a d-bag that is 5.5" OD and 18" long.
