You should video the whole build and do a youtube channel!
Love this! |

Sometimes think about it. Or alternative ways of publishing.

   Now all finished externally with stone grips. Only the valve components left to make.

How does that trigger system work?
From what i can work out, its in the fired postion.amd when you cock it it lifts the sear up onto the bit sticking up next to the spring and trigger sides backwards as opposed to having a pivot point. |

Please also post some videos or youtube links showing it being fired once you've got the valve done

Yes bead blasted. Requires preparation to keep the beads out and thoroughly cleaning any that make it inside.

Yes that is how it works. The two lower legs of the trigger can be drilled and tapped with a travel stop screw on the forward leg and a ball plunger screw (2-stage feel) on the rear leg, allowing it to be highly adjustable with a short break. But with the addition of the safety lever I have left this out to make the safety safer. The trigger is nice enough as it is.

Here you go. I have not yet added up the costs for this but the stone grips added a significant amount.  |

Is there any particular advantage to the trigger system ? Does it get used in other firearms or is it something you've designed. I've nit come across it before.

Which part? As a whole its advantage is doing the job efficiently and effectively. I have not seen this combination used before but each of the elements have been around. e.g. the drop sear or falling sear is more common in rifles or higher end pistols or in extreme modification of Crosman 22xx grip frames. In pistols like the 22xx the geometry does not readily suit a drop sear so usually an intermediate lever needs to be added. This introduces more complication room for play. Although a well-positioned intermediate lever can get the triggering force to nearly nothing. Not using a drop sear, like the standard Crosman 22xx, usually gives a more creepy trigger break as you are un-wedging it from the striker against the full force of the spring. |

Cheers for that. Its a hell of an interesting concept.
Especially as i wasn't aware of it. One more set of questions or assumptions... Im assuming the two faces literally have a thin layer of grease/ mso2 that the falling sear rests on. Working much like the theory of a tyre aqua planning on water, giving zero friction to that part How quickly do you estimate the corners of the falling part to round and lose the crispness of the 90° corner. Will rounded corners then slip a tad earlier and the drop become a smoother slip than drop. How pratical/or how much more pressure would it, in your view, exert if it was holding back a piston and main spring? Or is it that its only holding the hammer and it's light spring back that makes it viable. |
