    That is not my understanding.
    To relieve pressure, reduce the gunpowder or change type.

    The ports on the barrel are to re-direct the recoil from an upward flip of the barrel to a more direct...

    Why do you want to use a boring bar in this instance? Tiny holes mean tiny reaches. I would use a drill ( and ream if that much precision is needed.) A gun drill would probably be best (but not...

    Some of the Olympic rapid fire pistols have several ports drilled in the barrel in front of the chamber to relieve pressure (and, presumably, decrease recoil.) I think one hole an inch from the...

    There are certain advantages to being a moderator, one being that you can lock threads, another being that you can have the last word. It is time to exercise both.

    We have almost 2500 posts in...

    What would be the increase in speed when the same 38 round is fired from a 6" compared to a 4" or 2" long barrel hand gun?

    Revolvers and revolver cartridges are a separate beast from others...

    Probably be a good idea to post a pic of your cannon and a list of needed parts if you expect to get any offers.

    I am a moderator over there, too. If this doesn't get cleared up in a week or so, PM me here and I will see what I can do.

    By the way, Orange has been marked as a spammer.

    In my limited experience with ABS, you can repair cracks with a solvent like MEK (Methyl Ethyl Ketone.) Put a wet Q-tip dipped in MEK against the crack and surface tension will draw the MEK into the...

    ... I'm getting no answers.;

    It's a holiday in the US this week/weekend; not likely to get a response before 12/2 PST.

    If you have a Bridgeport or clone, rotate the turret (which holds the ram) such that the spindle is not over the knee. That way you can hang the barrel vertically from the side of the table. You...

    Note also that both Giffords and her astronaut husband Mark Kelly are gun owners.

    Lots of left wing politicians are gun owners. They are important people and need to be able to protect themselves.

    Once you understand that the purpose of the TSA is not to make you safer, but to condition people to be submissive to authority (an extension of the educational system,) it all makes more sense.

    I think it would since the threads would be stretching relative to the barrel shoulder which would lengthen the chamber. I don't speak from experience here, just mental analysis. I do know that...

    I don't know how frequently you intend to switch barrels but unless you hardened the shanks, you risk moving the threads (which will effect headspace) each time you tighten the barrels. If you...

    8620 will not harden without some form of surface treatment like carburization. It doesn't contain enough carbon.

    I hope that you will deal with the offenders individually instead of locking the entire discussion.

    Unfortunately, I personally can only lock the thread. I can ask the forum owner to ban a poster...

    I think you should use a boring head and boring bar. That will give you the best control over location. Drilling/reaming location will be worse.

    Although I see you plan to use a CNC mill. In...

    I had 2 failures to fire.

    How old is the ammo? Never can tell how it has been stored.

    There is nothing more important than free speech.
    Nothing.

    If you look closely, the left is promoting the idea that "hate" speech is not protected. Who gets to determine what is hate speech?

    It won't ever happen. ... Nobody's taking your guns, today, or in the immediate future.

    If that turns out to be true, it will be because us owners defeat the current generation of antis. It's...
