    Very interesting post i am very happy to see this publication at last here. As you can see in the following subject I have been workink on it too but whit lost of references problems think to Bede Dwier and Dr Credland ho finely provide me whit data. This realisation is certainly not perfect but it work pretty well. I see in the video that you have publication about it would it be possyble to have one? Anyhow can you provide more technical detail about your work

    If you do a Search here on Chinese Repeating Crossbow or Repeating Crossbow you will find several references. There have been a number of people make re-creations of the Chu Ko Nu, particularly folks involved with ATARN.com the Asian Traditional Archery Network. The group here has much more emphasis on European crossbows than Asian.

    What is the source of those illustrations? They aren't ones I'm familiar with from any of the conventional sources.

    Thank you Kenh. But I am not doing this distinction between far east and westerne crossbow they are crossbow!!! More then 3/4 of my research are about westen, medieval and modern kind they all got there importance in the progress of crossbow. There you can see a part of my work about Chinese archery's.
    https://thearbalistguild.forumotion.com/t434-korean-repeating-crossbow.
    I just wanted to greet Dr Chen Yaojun ho add a important stepp to or knowledge. The documentation come from the Chinese archaeological journal "Wenwu" n° 5 in 1990. They product a copy wich is exposed in the Beijing war museum. My reproduction could be made, thank to Bed Dwyer, Folowing his article in the 2011 issue of "Journal of the Society of Archer Antiquaries". And I am still looking for Dr Yaojun original (and drawing). By the way I really like the superb craftmanship you produce in yout crossbow.

    Very interesting design, and nice re-creation.

    So this was fired by pulling back with a motion similar to a conventional archery bow -- holding the tiller chin high, pushing out with one hand and drawing the other back to the ear or jaw?

    Thanks for your comments on my latest build. I like the Han Dynasty prod binding technique:

    I am glad to see it arouse the interesting of others.
    Here is the source of Mr Chen yuejun's(陈跃钧先生) thesis (written in chinese,may be hard to read, but the drawings is vivid and useful). In my opinion,the thesis is quite precise and loyal to the excavated cultural relic. By the way, downloading of this pdf file in the official scholar database is forbidden,so we must thank the sharer.

    This ingenious weapon(often with poisoned arrows) was designed for VIP's self-defense or murder, the King,queen,generals,etc. It is believed the prototype of the latter Chu-ko-nu. Chu-ko-nu is much simple, useful and dangerous than Chu-state repeating crossbow.

    Interesting weapon!

    My biggest critizism about the design is the distance of the two bolts. The string will no doubts tend to force the bolts together at release, and this will create unwanted friction. In the end it seems that the bolts are forced through round holes, but they will bend and chafe before that happens.

    I am thinking about a modification of the design for pretensed rubber.

    The two-shot mechanism does seem like it would have a lot of extra friction. The string where it passes through the body and strikes the bolts seems to be either a separate rigid bit of metal, or the string is covered with something like goose quill to make it rigid and prevent to 'collapsing' string from pushing the two bolts at odd angles.

    Looks remarkably like some of your designs, Joerg! Chu-state repeating crossbow (20 arrows) 524936

    I noticed the "rigid" part. That will limit the power of the weapon, as it will hit the wood with full speed and serious momentum. I think that poison arrows would be really called for as the physical damage these bolts would have caused must have been very limited.

    I was not satisfied with the first "Chu" that I present you, I produce a second one with the additional info from the Chinese post. This one look better and very close from the original. Like the first one The big trick is to be perfectly accurate wit the measurement. It is a small item and every thing depend of the quarrel diameter and lenght if you dont respect this, the quarrel will fall or get stock in the magazine or the rope will rub to much. This is one aspect but the to pieces trigger work whit gravity and have to be perfectly realised to work freely for this the all the mortises have to be accordingly. So it look easy but it is frustrating. It took me more time to do this little think then mi last Skane type crossbow. But at last it work. With a very rigid quarrel (mine is alloy)of small diameter with an extra point and a good bow it is very impressive at small distence . I would not for any reason expose mi face to this nasty little beast !!! You are right the two quarrel produce friction I am planning a rigid peace to stike them same time. To get a maximum efficiency I load only one pile of quarrel in one side and then is almost as powerful then a classic pistol crossbow (but semi automatic). So work is not finished I have to come back realising better quarrel and finishing a new rope with mechanical rigid striking part. In mi opinion if this type of crossbow was not developed is because it need a lot of fine adjustment how are time consuming and it probably not worth te money and the time spended for the resulting efficiency. But the realisation is a very fun challenge. JoergS is right it should be very interesting to produce a rubber propellent version . I am also considering the possibility. I post some pictures, within a day I'll post a video.

    Here is the loading and shooting video. Darts go two by two but is more powerful to load one pile only .10 darts in on pile total 20.
