DIY Barrel Rifling Tool

Hat tip to Bryan S. for sharing this with me.

Here is a guy who made his own barrel rifling tool with some components he had lying around. It is rather clever how he does it.

Here is the fruit of his labor.

    How do you vary twist rates?

    • Nicholas Chen

      I guess, you have to remake the main tube at the beginning of the DIY video. Where he welds that wrapped wire to the tube. By changing the twist of that piece then you will vary the twist rate.

    • PK

      Different twist rate on the cam. You have to make an entirely different one for each twist rate required.

  • So, on one hand, the final product doesn’t look all that hot.

    On the other hand, rifling a barrel has always been considered one of the “really hard” tasks when it comes to home gun manufacture. If you can make even a slightly crude rifled barrel from some steel pipe and common tooling… well, that’s interesting for any number of communities, let’s say.

      I mean it looks better than the rifling on most Mossberg barrels.

    Howdy bubba, u all gunna love this new fangled musket carving drill I dun did develop. I call it the spinnazier.

  • Ron Fox

    I need to do this on my AB-10. The rifling in its barrel is pretty much non-existent

    Okay let me try this again….

    Enter “Lautard barrel machine” into Google search. Go to the link “bill webb’s rifle….” and buy the plans for this deep hole drill/cut rifling machine that’s buildable with a 9in lathe, horizontal mill, drill press, etc.

    It’s claimed that the one pictured produced a 1/4in capable 6mm benchrest rifle. You’d probably get a slightly better barrel buying it from Krieger, but then you wouldn’t be able to brag about having made the barrel. And machines like these will come in handy when gun confiscation becomes a reality.

      Make sure you include the instructions on how to fold your tin foil hat too.

        Google is your friend, but use somebody else’s card when you log into the computer at the public library.

    • JK

      If you already have a nine inch lathe, horizontal mill, etc in your garage/shop, then the Lautard would be the way to go. Me, I’m lucky to have access to a drill press and grinder. The rifling tool in the article makes a completely homemade zip gun much closer to being a practical pursuit for hobbyists at my level of equipment. Otherwise, I’d simply order a barrel blank from Green Mountain or the like, or re-purpose an existing spare or scrap barrel, which seems to reduce the purity of the endeavor.

      Besides, after they come for the guns, they’ll likely be keeping a rather close eye on hobbyists/individuals with all the machining toys. Fewer toys=less scrutiny.

    brilliant design to make down and dirty barrels, certainly good enough for minute of man accuracy, The only problems would be that you cant shoot plain lead bullets at all, the rough surface would strip so much lead off of even a hardcast bullet that it would need to be scrubbed down thoroughly every few shots, and FMJ bullets would probably get you a few hundred rounds before you saw a degredation of accuracy due to extreme copper fouling.
    Obviously problems would compound themselves when the barrel gets hot, none of it is stress relieved so high temps could cause alot of wierd warping issues and erratic points of impact, even with a cold barrel that cutting process would turn a “straight” well as straight as someone would be able to make barrel with basic tools into one with multiple points where the stress of the cuts had tweaked it. Tweaking the design to use a CNC bit instead of a drill bit would get you cleaner cuts and a reamer would ensure the lands were smooth.

    I would like to see that design adapted to use an actual bore reamer and an actual rifling cutting tool. A button would probably be the best bet since it cuts all the rifling at the same time so you dont end up with odd stresses, and you dont have to try to manually time the rifling, and could be done with a hydraulic stand press that are pretty common if you chose to force the button through, and maybe you could thread the rifling button to pull the button through, but I suspect that would end up proving to be a problem.

      Maybe a few shots with some steel case ammo will smooth it out.

      • CZFan

        nah the jackets are no harder, but that does make me think about those rounds with polishing compound on them to hone barrels, you certainly could use them to smooth out some rough edges.

    This is something that many politicians just don’t get. No matter how many laws you pass restricting and banning firearms, there are plenty of people in this country capable of making them from common parts, using common tools.

    Just like hippies don’t understand that wanting “everyone to love each other in peace” only works until the first guy shows up who doesn’t love everyone and lets himself be guided by regular human nature.

      Prohibition doesn’t work. Any kind. Ever.

  • Adam

    Reminds me of the early cut rifling machines, And i mean EARLY….

  • Leemerk Rockwell

    Are you willing to provide a link to that grinder?
