This is part 3 of my 12 gauge, break barrel, black iron pipe shotgun build.
Being able to measure things accurately is very important when engineering and building things or even repairing things so that's why I always use a precision caliper to measure things when I'm in DIY mode. Harbor Freight and Tool sells a digital one (4" capacity) that does both metric and English for $15. (4 in. Digital Caliper Pittsburgh - item#47256 ) Like most calipers, It does Inside/outside/depth measurements to .001" accuracy. If you can measure with precision, you can do precision work with caveman tools. I use mine all the time when I'm DIYing.

$14.99 retail. Fits in your shirt pocket so it's real easy to take with you to the hardware store.

Here's one online source for metal stock:

Lots of plans available for other firearms built in a similar way.

I made this shotgun for myself because I love simple firearms. This project was an opportunity to learn, and doing it was outstanding entertainment. I have no intention to ever sell this shotgun or give any firearms that I make away so please don't ask me to do that. I also have no desire to make parts kits for firearms. Check out the links above because there's a lot of gunsmith knowledge and insight at those links. ;-)

Thanks. Cricket.
