    Tuning Hatsan flashpup hammer

    I would expect someone capable of machining a new hammer would consider weight and spring tension and possibly install tungsten inserts to maintain weight and also cause a change in sound profile, since it is more dense than steel. No doubt a regulator will change a cheap gun, making it quieter...

    Tuning Hatsan flashpup hammer

    Sorry this video is made for a friend who is kind of a beginner but I have a few places in it where I shoot my gun and I am wondering how it's noise level compares to where you are at with yours? I also want to do something about sound deadening portions of the stock, maybe with some stick on...

    Tuning Hatsan flashpup hammer

    I don't know that I would consider a piece of 16mm round stock steel bored with a 60mm deep hole on the back, to accommodate the 20mm long adjuster, 4mm long spring spacer and approximately 25-30mm long of smooth bore countersunk area to allow the spring to move smoothly, a solid piece. Steel...

    Tuning Hatsan flashpup hammer

    Maybe but Delrin comes in different grades and is a very dense heavy plastic that is turn-able on a lathe. They use it to make very large pulley sheaves, for the load blocks on industrial/construction cranes, as it is softer on the wire rope than metal sheaves. I would envision a bi-metal...

    Tuning Hatsan flashpup hammer

    There probably is only so much that can be done with the gun. The way it is made is not conducive to sound deadening. The receiver walls are also very thin which does not lend itself to sound attenuation. I notice if I knock on the side plate of the cheek piece, between the adjusting screw it...

    Tuning Hatsan flashpup hammer

    It would seem the entire hammer could be turned out of a piece of Delrin plastic and that would be impact durable.

    Tuning Hatsan flashpup hammer

    When I ran the short 12mm long hammer adjusting screw I dropped in a thick 8mm o-ring between the spring and adjuster and it sounded more dull, but not a lot, like when you put in a depinger a gun. On some guns the depinger makes a huge difference and on others it just kind of dulls the sound. ...

    Tuning Hatsan flashpup hammer

    I have been experimenting with quieting the hammer end of the Flashpup gun. What you might try is to take out the hammer spring spacer and replace it with a couple 8mm o-rings or something like that. I was playing with various ways to reduce spring tension for lower the velocity out put of the...
