A new kind of bow (Read 4527 times)

timpa Interfector Viris Spurii Offline Stones in the horizon Posts: 1515 Finland	A new kind of bow Feb 25^th, 2015 at 6:20pm I designed such a bow. At least I have not seen this before: https://www.youtube.com/watch?v=xG5gWCM7yzo

Posts: 1405 Gender:	Re: A new kind of bow Reply #2 - Feb 26^th, 2015 at 11:36am I know nothing about springs and less about metal, but I'd think that a longer draw would reap more benefits. I'd also be curious if the real benefit was heavier arrows at about the same speed.

This idea is: - there are two bows, bow 1 and the bow 2. - The bow 2 is attached to the bow 1. - In this case, the whole the bow 2 moves of the bow 1 force. (Sorry for my English.)

For some neat bow designs, check out cable backed bows and Native American compound bows, not the kind with pulleys, the kind with two bows built together.

Jlasud - more power = more draw weight. You won't get one without the other. But packing more power into a smaller crossbow is damn clever

nothing new here. Sad

double bows have been around for a long time.

using double bows on a cross bow is not new. Cry

Your specific layout may be new. Wink

A paleo legal (no glue) compound bow per its designer.
made with split wood and cordage.
The trigger is notch, lift peg & lever
prods are held to notches in the tiller by the strings tension

It seems: We have uploaded videos almost at the same time: Joerg: 22.2. my: 24.2. @Steven: It seems: it is not new under the sun
