Using paracord 550 for tillering

[FilipT]

Thanks Del

Here's an earlier version I used before I realised a simple ring worked just as well and was easier to make!

I have similar things to this at home and rings too. What inside diameter of ring you use and how much shortening of string can it do?

OD 37mm   (Outside Diameter)
ID 16mm    (Inside Diameter)
Thickness 10mm
Each turn through it changes the string by about 1", twisting will give fine adjustment.
It could do to maybe be a bit thinner, or smaller OD as 1" is a little too much. The ID is about right as it allows you to thread the string through the hole nicely.

Thank you. So it seems you don't really need put much loops through the ring for adjusting.

550 Paracord is absolutely fine for tillering.  I've used exactly that on all my bows, up to 145lb or so.

Remember you should only be using it to get the tips of a bow bending 6", at which point you fit a proper string and tiller from brace height.

[FilipT]

That makes sense, as after tips go past 6" of movement, stretch really shows. I don't know does your 550 stretches after that.

[WillS]

I don't use it past that point. 

What Ian said is important though - if you've got anything stretchy in the setup you'll struggle to work properly.  If you've got poor quality 550 that might happen, but I'd be surprised.  I know you don't have a tiller set up yet, so when you get your pulleys and rope try the 550 again as it should work just fine.

[FilipT]

Ok, thanks, but planning at using spectra fishing braid as both tillering string material and regular string in the future.

Ditch the 550!
Climbing accessory cord.....It is in another league
Del - fastflight is dyneema
Personally I make a fastflight string with about 20 strands.

Yes indeed... I use Fastflite as a generic name for one of the plethora of modern low stretch materials AstroFlite, Angel Majesty et al... what I really mean is anything better than Dacron!

Has anybody tried  FARMERS 10,000  its great for tillering and has many other uses .

A while ago I switched to Del's technique, and I find it to be the cat's pajamas I use a continuous loop string for tillering, made from Fast Flight, with both loops served. Use it right to the end of tilllering, and when the bow is done, I use it to make a proper string of the correct length. That way the string serving on the "good string" isn't roughed up during the tillering process.
