I'm thinking a 'nipple' type arrangement (like a motor bike cable) but at both ends, if that is the case, some sort of 'industrial' manufacture seems likely.
One of my 'to do' lists includes trying to make a traditional crossbow. was originally thinking of forging a steel prod (once I've made my forge....that's also on the 'to do' list
) But recently acquired 24" of buffalo horn .....so now toying with the idea of a 'composite' prod .....horn, wood and sinew.....
I think 50lbs draw is easily suitable for small game. My compound bow's draw weight is around 50lbs and would send an arrow approx. 230 feet per second ….I would expect a bolt / quarrel to have a similar speed at the same draw weight
