12 Gauge Shotgun Perimeter Alarm - Build Your Own

Building a 12 gauge shotgun perimeter alarm for camping, hunting and warn thieves. Intended to use training blanks, it is fun to build and play with!
Check out TAOFLEDERMAUS video where they experiment with various 12 gauge ammunication • 12ga. Camping Trip Ala...

Well that worked out. If I lived as close as you are to Seattle I would be using double OO. Be safe, fun project.

[@hilltopmachineworks2131]

For sure!

[@woodscreekworkshop9939]

and maybe add a barrel 🤗

[@JamesDedmon]

Most definitely lol

KZbin BUILD OF THE YEAR !!! Congratulations and welcome back

[@woodscreekworkshop9939]

thanks my man!

[@JamesChurchill3]

I just use primers, I think the powder needs to be in a breech for it to build up enough pressure to explode, in this case it seems to act more as a suppressor, I'd be interested to see a comparison between a full (blank) shell and an empty one with just the primer detonating. Good build, looks very pro!

[@woodscreekworkshop9939]

Thanks James

1 game, 3 tries, $150. Kinda expensive toy. Anw dont let your son see it.

[@woodscreekworkshop9939]

my son wasn’t too impressed with it 🤷🏻‍♂️😁

[@TheMiniMachineShop]

Gives me a great idea for a mole problem in my front yard... Cheers!!

[@caddytrekguy]

Another cool and generous GAW….fitting for an epic milestone 💪🏻 I gotta look around, I’ll bet I can find something that can go in this one. 🤔🧐

[@AmateurRedneckWorkshop]

Well done Yuchol. That should last about a hundred years. I even liked the music in the video which is very unusual for me. I made a similar item one time but for using loaded ammo. It was actually harmless and I showed that in my video "Certain death or not". youtube hated it and demonetized it until people had already seen it.

[@woodscreekworkshop9939]

Yes, harmless for sure.

[@EverettsWorkshop]

Came out well, the zip tie grooves make it look kind of tactical! I know having something like that in the mountains where I'm from would be handy for camping as the black bears are into everything if they can.

[@woodscreekworkshop9939]

Thanks Everett. I’ve had enough encounters in the woods where this would’ve been handy. Strangers coming too close, moose, other animals, your mother in law raiding your fridge at midnight...

[@outdoorinterests]

I love it but unfortunately it's not rain proof. It soon corrodes and binds up. Even the primer gets wet and soon stops working.

[@caseykelso1]

Like everybody has a Mill and lathe just laying around the garage😂 thumbs down it's not d i y for the normal guy

[@Mekhanic1]

It's great for Amazon packages!

[@woodscreekworkshop9939]

[@jamiejohnson8176]

I wish I could make them I can't afford 30 to 40 apiece

[@Saa45MIV]

You only need 200k worth of milling equipment to build one of these

[@FrancisoDoncona]

Or add a washer made of steel and cut the lock clip leg off.

[@mikem5043]

Could you make the groove for the shotgun shell rim with a slitting saw?

[@douglasthompson2740]

Curious to know when you tested if that hairpin clip offered to much friction? Might be that a straight pin would be more effective to that leg brush that will activate it without giving the intruder time to feel the wire and step over it? You probably did it off camera but I would have chamfered the striking surface of the firing pin to keep it from acting as a punch and penetrating rather than dimpling the primer which results in gas blowback (probably not so much with no projectile going out but still not a good thing)

[@woodscreekworkshop9939]

I think a straight pin would be smoother for sure. I chamfered the firing pin tip, but it only dimples the primer, no penetration.

[@michaelrosenlof1084]

Yuchol, it may be time to switch to decaf brother…😜

[@woodscreekworkshop9939]

[@chronokoks]

Ouch "failure to remove object from the foil wrap during hardening process" with you too now. First Tom and now you :D Somebody should figure out a or show a good procedure on how to do this.

[@bigmotter001]

I thought California and Washington outlawed using the words firearm or shotgun except politicians? It's still a great informational and entertaining video. Great to have you posting again. Keep it up and take care!

[@zachaliles]

I was thinking, you could probably make some that use .22 blanks instead of shot shell blanks. .22 blanks are easier to come by, they sell them at most hardware stores and they come in different power levels. Since all you're looking for is a loud pop the .22 blanks will fit the bill and do it possibly cheaper.

[@一只猪蹄]

你好先生，请问能给我计划吗，非常感谢你❤

[@raverdan]

Don't you own an air compressor? Just curious using that air in a can would be expensive. It is here in Australia anyways. Love your work.

[@fithopsllc]

Very cool!

[@MattysWorkshop]

Gday, great to see you back mate, I think I need one here, every now and then there’s a critter looking to knock stuff off around the house, awesome build, cheers Matty

[@woodscreekworkshop9939]

I was just wondering what Yuchol had been up to. Figured maybe working on the new machines, maybe some projects inside the house. Not what I was expecting XD

[@woodscreekworkshop9939]

[@woodscreekworkshop9939]

[@glennfelpel9785]

Good to see you Yuchol. Thanks for sharing this interesting stuff. Did you ever just try a primer.....likely that isn't loud enough. What do you the expert think.

[@woodscreekworkshop9939]

I have not tried just the primer. I may have to experiment.

[@carneeki]

The general theme of the project and the music at 4m45s reminds me of FreedomToons :) Cool project!

[@woodscreekworkshop9939]

Thanks Adam

[@silverbullet7434]

I think the firing pin may fail , if you had a radius at the base of the pin it would increase strength many times. Not picking just what I see could be better . most firing pins are tapered to help slow breakage .

[@woodscreekworkshop9939]

It is tapered and radiused

[@justdoingstuffrsa751]

Best vid I've seen thus far.

[@edwerts7096]

If you get a 12 gauge chamber reducer you can fire live pistol ammo out of it. The reducer fits just like a shell does but is chambered for a pistol. You can build a frame to mount it to. Works as a great back up shtf device.

After many years of reloading shells. I have found that just the primer in a shell is just as loud if not louder than a blank or loaded shell. At least in 20 gauge. Great videos. Thanks
