    Harcourt Park? Abort!

    Get the range of the Auckland City Council and fire for effect.

    Don’t tease me.

  3. The neighbors are nervous, yes?

  4. Murray says:

    No one has complained about the power tools.

    And when he fired the noon gun fifteen minutes late, no one noticed.

    Cheers

    What sort of cordage do you run on these? I suspect Kevlar/Spectra/Dyneema would be a bit too stiff?

  7. Murray says:

    I use absiel rope as it has very similar properties to sinew but without being as sensitive to moisture.

    I also use cored out absiel rope for the strings. So not very springy but more flexible than climbing rope. The best results would come from something like paracord. I’d only need about 100 metres of the stuff for Vespasian so a little out of my price range.

  8. Back in my boyer days nylon mason’s chalk line was used for cordage backed bows due to its similarity, tensionwise,to sinew. Cheap too.

  9. Murray says:

    Thats worth knowing. I’ve dwesigned a bow powered tennisball thrower but we’re having trouble creating a bow that will do the job due to our rubbish timber in this country because good wood is only for looking at.

  10. Do a google for cordage backed bows and inuit bows, somewhere out these there is a knotting pattern.

    I got to see it on Sunday. Very impressive piece of engineering.
    Well done for all the work you and fellow recreators have put into them.

  12. Murray says:

    Thanks Brian, hope you enjoyed the day.
