splicing tachron

Does anyone have any tips for splicing tachron? I'm having a hard time getting thefid and core through the cover where the core is still in.
 
Don't feel bad, I don't know of anyone who uses fids to splice this rope.

One trick you could try is to step down a fid size. So with this one, you can try a 3/8 tubular fid. The fid might make it, but the challenge is getting the core taped up snugly to the fid.

Or just ditch the fid and go with a splicing wand or wire fid, it will save you a lot of frustration.
 
I know it sounds crazy, but the technicians at NER have demonstrated that Tachyon retains more of its strength if spliced with a hollow fid vs. splice wand or wire fid. I can tell you personally that I was able to get a few to break at strength using a wire fid, but all of the splices using a hollow fid have broken at strength....most actually above strength !!

If you remove about half of the core roughly 5" down prior to inserting and taping it into a 3/8" fid you will have much more luck in passing the crossover with a fid.

Good Luck and keep at it !!!
 
Incidentally "breaking at strength" for Tachyon = 6,000 lbs. While most lines have a +/- percentage of acceptance for strength ratings, Tachyon does not.. It must break above 6,000 or it won't get OK'd by NER.
 
yea, we'll see......I have a couple ready to go for our break testing day in a couple of weeks.....but just for kicks, maybe I will do one using a fid.

I'm looking at a Tachyon splice we just tested showing 6,390 lbs on the break tester. No fid except for the measurements.

Must just be my magic touch.......

Anyway, I'm looking forward to our break test day coming up, it's gonna be great!
 
Re: splicing tachyon

Most every Tachyon splice my guys and I have done with a fid has broken above 6,700 lbs...the majority in the 6,900 lb range.

I can't wait for our "day of destruction" !!!!!!

ps I found that monster True Blue that Ryan "overpaid muni-guy" Lewis did an experimental splice on....with his permission I hope to blow that sucker up too !!!
 
Re: splicing tachyon

I can only imagine what Ryan cooked up. Are you bringing a True Blue splice he made? Man, that guy DOES have a lot of time on his hands!

Can't wait to see this one...
 
Re: splicing tachyon

Here's my first splice... not the first attempt! Thanks for the tips guys.

Very interesting Rich. Why do you think that is or does NER have an explanation?
 
Re: splicing tachyon

My guess is that due to the "second core" there is very little room for manoeuvering and that somehow the fid is more streamlined than a folded over bit of core on the wire fid and during the crossover the folded over section somehow damages something.

Another possibility is that the tested splices were all 12" eyes and since my wire fid was too short to do the whole pull it was necessary to exit in the eye and re-enter in order to complete the crossover. This certainly would cause more damage to the sheath than running through the eye and crossover with a hollow fid.... In fact, I believe one of the splices actually broke in the eye (above 5,400 lbs, but under 6,000) instead of the normal break point...kinda points to this possibility....maybe ???
 
Re: splicing tachyon

That's quite odd. I wish I was there watching them splice it with a wire or wand. I don't feel weird resistance when passing the wand through or bringing it back.

It would seem to me that the fibers are flexible enough and resilient enough sortof "resituate" themselves while finishing up the splice.

Might have to get more busted- but haven't had any break below 6 so I should be good. But maybe switching fids will give an even higher score!

Thanks for sharing.
