QuoteWe did try recently the reserve Slinks on the Sigma mains again except with the main Slink bumpers inverted to keep the slider up higher, but the slider still was pushing down too much and quickly started melting the outside of the Reserve Slink (in 30 or so jumps). The slider on the Sigma mains rides solidly against the risers/Slinks. So we're back to the metal links again on the Sigma mains.
If the Slink bumer was inverted, how come the Slider ws able to touch the Slink? Did the slider go OVER and down the Slink cover, and then touched the Slink?

The Slink cover is fairly flismy (type III tape) and made to cover the top of the riser and hold in the Slink tab & keep slider up.
So when you turn it upside down, the slider just squishes it down flat against the riser allowing the slider grommets to still rub against the Slink.

QuoteTry sliding your hand quickly down a Dacron line. You will only do it once!
I did it. Unfortunately, I did it before reading your warning here
...
QuoteApparently, the Relative Workshop/UPT tried soft links on Sigma tandems with Dacron lines, but ran into problems with hot slider grommets melting soft links, so they discontinued the practice.
... similar to the problem Lou Diamond mentioned on military freefall rigs.
If there is sufficient heat in the slider grommets from friction, wouldn't this also present a problem for melting/burning the suspension lines, too? Or is it not an issue because the dacron is more heat resistant than spectra?
Does this mean that the SR-1 slinks are not made of spectra, or is all the discussion here about using SR-1 and/or reserve slinks on dacron lined canopies more of a YMMV type deal?

Yes, Dacron is more heat resistant than Spectra.
PD Reserve Slinks - and soft links from most other manufacturers - are made of Spectra/Microline/polyethelene suspension line between 1,000 and 1,500 pound tensile strength.
What does "YMMV" mean?

Your Mileage May Vary...
If you are swooping and want the slider down and out of your life,then fine,,,but for everyone else whats the big deal with lusting after slinks ? Rapid links have made millions of jumps with few relative issue's,,i don't get it...![[:/]](/uploads/emoticons/dry.png "[:/]"){kind=small}

Soft links solve one set of problems (dented slider grommets and weight) but create other problems (cut Slinks).
Such is the way of inventions.

That's hilarious.Quotelusting after slinks ?

Actually, a #8 grommet (slider) will fit over a #3 1/2 or #4 Rapide link even after a cover is installed.

Yeah, they work OK. Last time I took mine off to replace the bumpers, I made-up some soft links & never looked back. BTW, for those of us who mfr. our own links, the soft variety are much easier and cheaper.

I suspect that half the problem is friction from Dacron lines. Try sliding your hand quickly down a Dacron line. You will only do it once!
I wolnder how long soft links last when used with smoother lines like Spectra?
We still use the Reserve Slinks around here on Precision, Aerodyne, HOP and Icarus tandem mains without issue. The HOP's and Aerodyne's have Spectra lines and the Slinks don't get any abnormal wear. The Precision and Icarus mains (some Vectran and some Dacron) have the same result, although the slider seems to ride a little bit above the Slinks on these canopies during normal flight.
