    hi guys,

    hi guys, i don't post often here so be smooth with me o_O. i have also posted it on another dedicated rimfire web site.
    not sure if printing rifle parts in the us is quite usual, but surely not here.
    i have attached some images of my rimfire action still to be cleaned up that i have drawn around the 40X PTG bolt in SW. material is 15-5ph and one detail i would like to mention is that
    there is an extraction cam inside of the action, something that would be very hard or impossible to do by machining and edm.
    if there's any interest, let me clean that up and i can post more pics. the other image is a section view.
    cheers
    mfg

    Pretty cool. How much cleanup is there for you to do? Not a criticism but the threads look a bit rough. I know nothing about 3d printed parts

    Wow very nice. This would save a lot of design time. love it, good luck going forward!

    WOW.

    What printer?
    What material?

    I know a little about metallurgy so I am concerned about burst strength from rearward bolt thrust but I'd be willing to try it.

    What? 3D printers can do stainless steel. How is that possible! What does a 3D printer like that costs?

    I thought 3D printers can only do "plastic" type material.

    Anyway that looks very cool. I'm impressed!

    ATF should be knocking right about...................now. How do you serialize the action for records keeping?

    He's in New Zealand. It will take ATF a bit of time to get there.

    Good to know. Thanks. But I can see this becoming an issue here someday. Just saying, stay on the right side of the ATF whether we like it or not they can really mess up a weekend or 40.

    They've been around for quite a while. 5 figures and up.

    There are procedures for making your own receivers . And laws regarding the sale of said receivers.

    What dimensional tolerances can be held with these? Just curious thats all. How long did it take to " print" ? Is the strength similar to a casting? Im more intrested as to when the aerospace industry will find a way to make this more cost effective than standard castings.

    Most actions are made from solid stock and machined. They are also heat treated to get harder. Matt
