    Well it looks like the guys at the machine shop finally got some of the Improved Chinese triggers I designed made and on Ebay. The price is a bit higher than I was hoping for but I think it ended up being more labor than I had assumed. If interested, you can find them here:
    Improved Chinese Trigger

    Or search for DIY crossbow trigger. It is shown as parts but should come all assembled with spring.

    Also I have been working on a How To video explaining how to build one of my cheap & easy crossbows. It will be in 4 parts. Intro & triggers, Making the bow, making the stock, and furniture (sight, stirrup, arrow clip, trigger guard).  It is not intended to be a "follow these exact steps" type, but more of a general guide with different approach. It is designed primarily to help new builders and part 1 is posted on YouTube now at:

    YouTube DIY Crossbow Part 1

    The worst part is the ugly old guy talking too much.  Embarassed   But I hope some of information will be useful. Any feed back from you experienced guys would be appreciated.

    Jaeger22, how do you recommend  anchoring the trigger in the stock?

    There two pins that pass through the stock and the two holes in the trigger case. They hold the case in place and are also the axles for the rotating parts. On the original Chinese they were the same size and looked to be about 5/16". These are 5/16" in the back but I reduced the front to 1/4" to get a tad more fletch clearance. Also it has a lot less load so it doesn't weaken it any.
    I have installed them with just the plain pins cut to be flush with the stock, and also with nuts and bolts. If you use bolts, just make sure there are no threads on the bearing surface. Especially the rear claw. If the bolt head and nut stick out too far they can interfere with the rope spanner if one is used.  So I made some with nuts and bolts that I ground down to be very thin.
    When I get video part 3 (stock) posted, you can see how I got it installed in the stock.
    Let me know if I did not make any of this clear. I can take some pictures.

    Hey Jaeger! I"ve been out of the mix for a while, great to see your design on the market. Looks very nice. I notice the production version doesn't include the backplate with trigger return spring. Was that omitted to simplify manufacturing or did you determine it wasn't necessary?
    I just got started last week cutting wood to mount the prototype unit you were kind enough to send, and I'm already trying to decide how many of the retail units to buy.

    Sorry, just re-read your initial post AFTER my first cup of coffee. So the photos on eBay are not entirely accurate, and the assembly does include backplate and spring?

    Yes, that is what they are telling me. They just took the pictures before adding them. Neutral 
    I will stay in touch with them to make sure they do.

    Please post a profile of the trigger itself so as  to better view the actual latching area.

    John, I had a chance to check out the YouTube video- not bad! The purists will probably call you out on your explanation of the medieval type lock mechanism, mainly because what you are demonstrating isn't really a medieval nut lock, but a modern hybrid with axle and trigger. I would recommend using a longer tool than the probe you used to stand in for the string in demonstrating the various trigger lock functions, as your hand was usually in the way. But, solid work, despite my nit picks.

    Great video jaeger, thanks!

    Is the 17" distance measured from the rear face of the Barnett prod to lock, the same as per the Panzer factory spec?

    Yes that is the way I measured it. I really like the Barnett prod. It cost more than my homemade but shoots faster and is a lot narrower.

    Thanks for the feed back Gnome.
    Yes you are absolutely correct. I thought about that when I watched it but was just too lazy to do it all over again. That was take 5. . . .
    Every time I did it I found something wrong, like getting in the way,  but at some point I had to just let it go. Embarassed  Guess I better not plan on being an actor! LOL

    The latest ebay images show very clearly the latch area and tell me the latch will be crisp and short-thank you.

    Just posted the 4th and probably last video in my little "how to build a crossbow " YouTube series. Although I may add one on a simple string making jig. This one is part 4 and covers making a PVC trigger guard, and arrow hold down as well as the stirrup and front sight from Aluminum. If interested you can see it here:

    I have probably red all your treads and watched al parts of your crossbow.  study
    I was looking for a new project and I found one cheers 
    Are you ok with me stealing about everything of your build. I could make a thread about it if someone is interested in the trail and error I encounter. Today I found some old wood that seem pretty clean and not to hard to handel, just fine for mark one. I like your chinese trigger so im testing one in wood. Bought some battens for the bow. Love your work and the site keep it up cheers
