    First topic message reminder :

    I often hear or read where folks are wanting to improve their crossbow trigger and in particular make the pull smoother and perhaps a bit lighter. And whilst understanding that the loads applied to a crossbow trigger when cocked, can be vastly more than those on a firearm trigger, there are some things that remain constant and are just as applicable to our needs. The following video from Brownell's wonderful website is most informative and provides much insight into how certain parts should operate together.

    Sorry, I don't have any sketch-files for triggers, but in principle they're very simple.  Payne-Gallwey's trigger on the full-plan Flemish bow is fine, except you don't need all those angles in the middle.  Essentially the trigger/tickler is an angular S-curve.  It goes back from the nut/sear about 2 inches, turns 90 degrees down and issues from the bottom of the stock, then turns 90 degrees back to lie along the bottom of the tiller.  You could do a little fancy work... twist the material, put in a bit of curve at the rear end, etc.  Many 15th century German bows bend the trigger forward a bit and then make a sharp angle back.  Take a look at some museum pieces: you'll see that.  It's more trouble making them that way, but they look cool.  Geezer.

    I've been googling designs for a few weeks now, there certainly do appear to be quite an array to choose from. I'm wanting an old school bow but with the safety designs of a modern bow. Safety catch, anti dry fire system etc. I'd buy a full mechanism if they were available but none are for sale that I can find in the UK so I've been left with making my own, I've spent this afternoon designing a few simple ones, hoping to 3D print them to test.
    You've used a lot of words I don't understand there, time to learn crossbow parts Very Happy Thanks for your time Geezer!
