Make a Break Action Shotgun From Scratch!




Introduction: Make a Break Action Shotgun From Scratch!

This video Instructable will show you in detail how to build a single barrel break action shotgun from scratch. If you choose to attempt a project like this, please be careful and respect your area's laws. The first video will show how to make the steel mechanical parts. The second video will show how to make the wooden stock and complete the shotgun. On Friday June 12 I will be releasing the third video which will show how to make the ammunition from scratch. After that I will make a fourth video with a demonstration of the completed shotgun in action.

Step 1: Steel Work

This first video is the longest. It will show you how to construct the functional mechanical parts of the shotgun.

Step 2: Wood Work

In this second video I will show you how to make the wooden stock and mount the steel mechanism into it. At the end of this step you have a completed functional shotgun.

Step 3: Make the Shells

The shells for this shotgun will be made from paper tubes. The primer is a unique "sandwich" design with 2 layers of metal discs, and a packet of armstrong's mixture in between. The metal discs that for the primer also form the rim. The propellant I am starting with is black powder, but other things like ammonpulver or smokeless powder could be used.

    Are you from around arlington washington? The oso lumber and hardware drawing pad is what makes me ask. I grew up in that area

    I've drawn up designs for a 12 gauge break action using a simple design, I shall build one soon.

    I'm currently trying to build a percussion cap parlor pistol, so your info on the moving hardware parts will come in handy. Thanks for sharing!

    I made a pistol like this when I was a kid, using a plastic BB as the bullet and a capgun cap as the charge.

    Some of the antique parlour pistols fired rounds that were basically a lead BB and primer only, so my little toy wasn't that far removed from that.

    I used the smallest fuel line jag I could find at the hobby store as a nipple to fit the cap on and a piece of steel 1/4" ID styerene tube for the barrel.

    This is a really interesting topic to me. I would love to see this instructable fleshed out a little bit more and have some info on laws regarding building your own firearms, and of course safety if you ever plan on firing it.

    The first video has details about the laws at the beginning.

    For "fleshing out," there will be 2 more videos added to this (one for making the ammo and one for a shooting demo). The first video alone is almost 45 minutes and the whole series will be more than an hour.

    laws are state by state like here in texas there is no problem manufacturing a firearm for self use. but no mater what your state sais there are some atf rules that have to be followed.

    Given our international audience, I would advise starting with national laws regarding manufacture.
    Even in states with relaxed laws concerning diy firearms, you need to check county, city, and sometimes even homeowners association laws. You may find making the gun to be perfectly legal, but possession and use of the finished product will land you in lockup.
    to minimize your chances of finding yourself on the wrong side of a police visit, consider designating it as a blackpowder weapon, and keeping a few rounds of bp ammo around as proof. At least in the USA, blackpowder regulation are much less restrictive. Dont worry about the 'old timey weak powder" though. Any target won't know the difference. :-)
