Seal lath bindings, what to use?

I was intending to use hemp twine to lash the prod to the tiller on my current project, but, are sisal or jute viable alternatives? I have read Mac's thread from 2012, but what is the best waterproofing material for the lashing as it seems melted beeswax is not the best solution? Also, I had intended to use linen thread for the bow-string; does this need waterproofing too?
Thanks,
Andrew

I think linen thread just needs to be waxed alot just like any of bow string to keep it from getting too dry. Bee's wax is good for waxing bow strings I believe.

Are you trying to stick purely purist and traditional? If not why not use something like artificial sinew? But also for the waterproofing the cord bridle I think either linseed oil or Tung oil could do.

I am trying to go as traditional as I can, within reason.

If you can't get access to hemp I think sisal would work better then jute. Sisal is alot more stronger and durable then jute cord.

Hemp twine is obtainable online.  TWINE, not CORD.  1/8" diameter or a bit larger is recommended.  It is strong, and not flexible like artificial sinew (waxed nylon).  Linen is a good substitute.  Even though hemp will not stretch as it is applied, it may relax with changes in moisture, so it must be sealed to stay tight.  It was usually soaked with lacquer or some other sealant after being wound tight.  Tung oil can work, but linseed oil will NOT.  Linseed oil is designed to let water IN AND OUT.  It is used on wood to prevent rot and decay from sun exposure in wooden roofs for example but after a good rain, it will let moisture leave the wood to prevent rot.  It does not seal.  Tung oil will seal with several applications.  If lacquer is applied only to the surface, it will seal as long as it does not crack.  If the material is soaked through, it will seal much better.   You better make sure that your bindings are tight before you seal them, because once the sealant is applied, you will never be able to unwind the cord, and instead the entire binding will have to be sawed off and renewed with new cord should you ever need to remove the prod again or replace bindings that have loosened.
