500# spectra needs sleeving?

Greetings to all....

(For those of you who think they remember me, yeah- I dissappeared from the
net for about a year-thought I had lost my account, but hey, still got it-
Thanks to those who took care of the FAQ when I vanished)

Now, here is my question,

I heard that it is not necessary to sleeve 500# spectra line- is this true?
(I'll be using this line for some power flying).

Thanks, and boy am I glad to be back in this group!!!

If you make a knot to unsleeved spectra you loose 50% of
the strength. With sleeving and well done knot you _may_
loose only 15-20%. Is 250 lb enough for you? Unsleeved
knot can act as a fuse...

There is an alternative to sleeving with the heavier braided
lines. If the line is hollow core, you can splice a loop onto the
end. Then use a small thimble (either plastic or metal) to protect the
loop. You can attach swivel or a short piece of heavier line through
the thimble.

In order to splice the loop you will need a splicing needle. A long
time ago, the Rainbow Stunt Kite Co. used to sell the needle with
instructions on how to splice a loop. Maybe they still do. Fishing
tackle shops often sell the splicing needles too.

I no-knot my power flying lines. It's easy to do in such large
line, and gets the maximum out of the line.

My $0.02:

You don't need 500lb Spectra.  I usually fly bigger stuff in more wind than
anyone else around and I'm OK with 275lb Spectra.

Sleeving produces a significantly stronger knot.  If you don't break the
unsleeved line, then the line you are using is FAR too heavy.  You would
get much better performance from lighter line.

nb: The line weight and diameter has a significant impact on the performance
of Peels and Flexifoils - fat lines slow down Flexies, killing the power
heavy lines destroy the delecacy of control in a Peel.

You owe the Kite Oracle a boat anchor.

The technique I know my father uses now to save time in fixing line breaks
in Spectra is to sew the ends together.  I'm not sure if this would work
with really light grades (as this is mostly for traction work) and you
need access to a sewing machine but it is easy.

Mr Lynn of New Zealand Eh?  You wouldn't be a relative of *the* Mr Lynn

I seem to recall Peter joining Spectra with the same knot that is used to
join the bridle to the skin.

Ah, yes....the Rainbow Stunt Kite Co., thank you for reviving fond memories,
Marty.

After years (literally) of searching for that same excellent sleeving tool I
found that High Fly Kite Co., Haddonfield, NJ, carried it as part of the:
Top Shelf Knot-less System.  Fran was kind enough to send me ten of them.

Good Luck Sleeving!
