Spectra Cable Source

[sanddrag]

Just for future reference, McMaster carries Spectra, but the smallest diameter is 1/4". Joe, have you tried checking any local rigging supply outfits? We have some here that serve the movie/entertainment industry, who carry a large variety of ropes, chains, shackles, etc.

If you are looking for a slightly smaller diameter, I bought Spectra cable of 1.9mm at this source:

They have other sizes as well. I have been using Spectra cable since 1997 on our robots for all kinds of lift and winch functions. It has never failed us.

Joe,

West Marine in Harrison Township has a wide range of dyneema and amsteel. If you'd like, PM me with what you want and I can pick it up wholesale. We're using it for our lifting winch.

In case these places don't work out for you, try contacting Honeywell. They are the manufacturer. We got ours via our Honeywell engineer since Small Parts was out.

We bought a 300' spool a couple years back in Chicago during the Midwest tournament from a Kite Store. The story is long one, but the price is much cheaper at a Kite store ($75 for 300' instead of $100 for 100' small parts).

Second the fishing line recommendations, though they don't list diameters. We got some from:

Though there's plenty of other people that carry the jerry brown line. It's apparently possible to make pretty nice splices and loops with the hollow braided stuff if you have a a fancy hook for pulling it through itself.

Raul the Magnificent!

Thanks.

By the by, what is the breaking strength of the 1.9mm Spectra string?

Usually in the neighborhood of 500-600 lbs (tensile). Be aware that a knot will drop the strength by as much as 50%, and that you should use a thimble to prevent it from kinking and chafing unless you're going around a solid shaft. Spectra is notorious for chafing (even though it is more chafe resistant that other aramids).

Are there any better/stronger crimps than those available through SmallParts and the ones that come with the cable?
