does anyone have the specs for the different lenghts of p line for the ocatne 7m, 9m and 13m. wanna make my own out of a decent rope.

2010 Octane 'P' line lengths. 7m= 1690mm. 9m= 1960mm. 13m= 2400mm.
cheers
Col

thanks very much indeed for that

Strongly reco anyone with Revs or Octanes (and others with problem puilleys) take a leaf out of the BWS Noise bag of tricks and replace pulleys with stainless rings.

The problem of the wearing P lines is caused by the pulley that is fitted tight to the LE which makes the lines pull through at an unco angle scraping on the housing. With stainless rings this problem disappears.

After buying a new REV1 and a then a new REV2 I became sick of making & replacing P lines. Ended up changing to Ozone. Still have my old REV2. Are you basing your recommendation on your own experience of using the rings on a set of REV P lines for 20+ hours or are you theorizing? I would have thought the friction over the ring would produce the same result.

@ Rob S
NO - I havent converted any of the older kites to this system so I guess you could say Im theorising.
But its a bit of a no brainer really. The Noise runs a very similar bridle set up with rings replacing pulleys at the LE point. These kites have been flown like this since the early days of R&D.
Yes "P" lines still wear. Any system that includes 2 surfaces interacting will create abrasive effect. The smooth & open stainless ring reduces this abrasive factor significantly compared to a line being dragged sideways across the sharp edge of a plastic pulley housing. You could expect at least a full solid season of kiting before any signs abrasive wearing - if at all.
@ COL
Yes. 'P' line spectra is very noticably thicker on the Noise.
Sorry not up with tecki rope speks. or Id quote the actual figures.

I'am doing the winter maintenace on my slingshot kites and have renewed all p-lines on my rev 2s but are having trouble finding lenght of 5 metre octane p-strings for the missus kite. Anybody happen to know what this lenght is your help would be much appreciated cheers.

Ill add a bit from our experience with the ring on the NOISE

firstly you can get some wear on the pline - but this varies with the user -
SOme guys have replaced their p lines in 3 months while i have not replaced any on the kites i have had and all those are over 6 months old and i ride way more the the average kiter - i think keep your kite free of fine sand is a key

secondly the ring does NOT twist the line - therefore eliminating the rope twisting the line and shortening it -

last point - the length of pline is critical to the flying performance of the kite -
if your kite is back stalling like the rev and oct tend to do then try adding another 10-15 of pline - you can experiment with extensions- or you could sell your kites and just buy the NOISE!!!! ( that was a joke)

hope that is useful
Bruce

Thanks Col

Remove the unnecessary ropes.
Bridal kites are for gheylords.

you don't often say something of value do you Luv

have rallies what pully's?

Does anyone have any suggestions for tying loops on 3.5mm spectra? I can't find a fid anywhere that small. Making my own p lines is an obvious way to go to keep the kite maintained, but I would like to avoid big bulky clumsy knots that I can so easily make that might not be so aerodynamic.
The rings sound like a great and inexpensive solution, thanks for that advice!

Hey Robbo (hope ur good)
Id still consider a quality pulley as replacement on the front pulleys. The noise has them there and I dont think they would be a problem at all being free to align properly on the lines. It was the skewed angle of the LE pulley that caused the problem.

You should check your gear more often slakker!

Hey mate, good to hear from you. hahah. I check it every couple of uses actually! Just never thought to check the pulleys!

Today I replaced the P-Line pulleys with small D-shackles and managed to free the pulleys on the front part of the bridle, but when I pulled the old P-line pulleys apart to get them off the lines, it became obvious why they seized up -- there are NO bearings inside and a huge amount of play between the hole in the pulley and the post so the hole will easily fill up with sand and seize up.

Hope to get a chance to test the kite on Thursday with a forecast of a decent southerly in Sydney for the first time in six weeks!

I also replaced the p-lines with dyneema again. Getting to be an expensive exercise! I'll report back how it works.

To dafish, you don't need a fid to splice this type of spectra or dyneema. Just get some thin stiff wire, bend about 20cm back on itself and push it up inside the rope, stick the tail inside the fold at the end of the wire and slide the tail back inside the rope. It is very easy as the weave is so loose and if you stuff it up before sewing it you can just re do it. Getting exact lengths can be a bit fiddly.

This is a great vid: If you don't have fids, just tape the line onto the end of any pointy metal object that you can push through the line. I used a double-ended screwdriver shaft that has a phillips head on one end (pointy end) and a slotted head on the other (to tape the line to). Worked a charm.

Ok I have replaced the LE pulleys with Stainless Steel rings and I have 2 questions.

1. What is the p line length for an Octane 11m? Only could find 7, 9, and 13?

2. Do you thread from outside in through the ring from kite end to middle or the other way around?

My last p lines lasted only 6 months. I am very hopefully the rings will help.

Thanks all
