    Chinese crossbow with auxiliary string?

    Post by HeroSK on Thu Jun 22, 2017 1:05 am

    Hi,

    Below crossbow is said to have excavated from the Tomb of The First Emperor, Lintong, Shaanxi Province Qin Dynasty, circa 210 BC has an auxiliary string according to some sources. What would be purpose of such a measure?



    Thanks in advance.

    Hello Hero,Welcome. No expert here. Two things come to mind though.The short string could be used as a portable basturd string. Another is it could be used to lesson the recoil of shooting lighter bolts. When shooting real light bolts , not enough energy is pulled from the bow , some times,  the penalty is a broken bow. I could see this as a help to stop the limbs from over reacting and blowing up the bow. Kind of like an anti dry fire .

    I thought this too.

    Maybe the extra string is a shock absorber/damper of sorts?

    Andy, Like I said,I'm no expert but that does make sense to me. After all , when  bow blow up,usually the main string is the first thing to let go.

    Given that the 'xtra' string runs thru the bridle passage, I dont think it's intended to be functional at all.  More likely it's an extra brace to keep the prod (lath) in shape while the bow is on display. I don't think the bowstring is original, and this 'xtra' string probably isn't either. I was wrong once... could be again.  Geezer.

    It looks like that 'auxiliary string' goes thru the hole that accomodates the bridle (binding that holds the prod in place) It's not likely any reputable modern museum would drill holes in one of their prize artifacts.  Though I've seen plenty of old crossbow bolts that had holes drilled thru to mount them on wire displays.... so you never really know.  Geezer

    Took a real close look at the bridle/string area.  A lot of Chinese crossbows, like this one, use a rectangular transverse "plank" to wrap the binding fore-and-aft rather than running the bridle through the tiller.  The plank slot is elongated fore and aft so the plank can be wedged in place.  


    This bow looks like it has a small plank, leaving the aft end of the plank slot open for the passage of the second string

    I've never understood why they didn't run the bridle-cord thru the hole, but you're right... they tie the bridle on each side separately to a plug. European bows almost invariably run the bridle-cord thru the hole and lots of them flatten out the the front of the hole to make it 'D' shaped.  I find that works very well for me.  Ahh well, different strokes.  Geezer.

    Hey guys, hang me if I'm wrong but, the discussion still does not explain the extra string. Or ,was I sleeping and missed the whole deal?  A pretty slow old fella hear.

    I think it's either a modern addition designed to keep the prod in its correct shape, or an ancient brace to do the same thing.  I don't see how it could fail to interfere with proper operation of the bow. Geezer.

    Geezer I'm in total agreement with you. I even went so far as to try the same thing on my crossbow . It bothers nothing when I shoot.
