Looking for a set of Aluminum folding spars for an original 18m P.L. Phantom. Anyone know who's still holding some in their bins? PistolPete - 24-2-2020 at 01:24 PM
I've made my own using 0.433 tent poles, inserts, and endcaps.
Note I thought maybe the thinner walled but larger 0.490 diameter poles might be stronger than the 0.433in thicker walled poles. Strength is nearly
proportional to pi*4*D*2*w (D and d are the outside and inside diameters and a thin walled tube w=(D−d)/2).
0.433 walled at 0.030 gives Strength, 0.3263
0.490 walled at 0.026 gives Strength, 0.3200
They weigh the same but the 0.433 is slightly stronger and fits the arc sleeves.Bladerunner - 24-2-2020 at 01:45 PM
I also used tent poles
Our Mountain Equipement Co-Op even cut them to size for me. They are identical to PL. Baluk - 24-2-2020 at 08:50 PM
If you're in a pinch, I used to fly my phantom with bamboo rods about 1" in diameterpbc - 24-2-2020 at 08:52 PM
PistolPete's nailed it with Quest Outfitters. They are the folks that supplied Angus with the materials he used to make the spars he sold. You won't
find better hardware.Ed Cline - 25-2-2020 at 04:17 AM
How long are these spars?pbc - 25-2-2020 at 08:22 AM
An 18M phantom needs spars 140 cm long. Always check the arc setup faq for these questions. I have a copy online at http://philipbchase.com/arc-setup-faq/PistolPete - 25-2-2020 at 01:29 PM

Thanks pbc
To save you time (lessons from some of my DIY experiments), I'd suggest you don't be tempted to use Bamboo or Metal/Plastic coated landscape stakes
from your local hardware store.
:embarrased:
Strength is also a function of segment length. Long rods like landscape stakes will bend and crease; then maybe tear your arc sleeve.
Bamboo is flexible even when doubled up. They might not break but the flex will allow your Arc kite to taco under heavier loads. This is not fun and
can lead to inverts, bowties, and long swims. shehatesmyhobbies - 25-2-2020 at 03:47 PM
Thanks for the link Pete, I've got plenty of Phantom experience, they in fact aren't for me but another guy who bought phantoms from me and split a
stock spar. I will get the supplies needed and make him some up, I was just looking for the easy way out if someone had a set sitting around in their
old bins.
