Hi Boyntonstu - welcome to HomemadeTools.net :welcome:
Alright, I'll admit you got a smile out of me on that video :). How'd you build it?
Hi Boyntonstu,
Welcome! :welcome:
OK, that's a pretty neat home improvement. What else have you built around the house?
Ken
Cool build, Boyntonstu! And still going strong after all these years huh? Welcome to the forums. :)
Welcome Boyntonstu. Liked your elevator. Do the wheels mark up the walls? Have been thinking on building one for a while but thought about using a pulley and counter weight system that could either be done by hand or with a small dc motor. The winch seems like a cheap and cheerful way to do it too.
However I got a bigger giggle out of the shot gun...too much fun but not enough physics. :lol: Thanks for Sharing! ~PJ :hattip:
I attached a pair of 3 x 1/8 tacks painted black.
No more tire marks.
Not enough physics?
Perhaps that is why I retired as a research physicist?
Thanks about the tacks...cheap n' cheerful.
No reflection on your background and did check out your YT channel...fun inventive stuff! Newton's second law came to mind with how tight the vice was for somewhere between 8-11kpsi for a 12ga. shotgun shell depending on how much and what type of shot, powder charge, etc. to the mass of your gun as to what reaction force might be...so the vice/clamp could hold it. ~¿@ The other part was the firing pin didn't seem to be secured so I assumed it shot back into the PVC stock, unless there was some kind of stop in it. Just a giggle and glad no one was hurt.
Me...I'm an old geezer R&D electro/mechanical engineer...having fun in my little shop and here on the forum. :hattip: ~PJ
There is a steel cap on the 101/4 nipple. The firing pin cannot penetrate the cap.
When you mentioned physics, my first thought was about barrel burst.
AAMOF This shotgun is far superior to store bought guns in burst safety.
Watch this video: https://www.youtube.com/watch?v=WwCP2Og__Go
And then this https://www.youtube.com/watch?v=BVN8_WeleAA&feature=youtu.be
The 10" steel nipple receiver around the barrel acts as a burst safety.
I actually didn't have much concerns for the black pipe.
It was pretty clear in his vids that he used a welded screw in a pipe cap and might assume that was welded to the pipe based on the last blow out (receiver Launch) in the second video. What was impressive was the plugged barrel actually broke the receiver away from the "Pipe Jaws" in the vise...but don't know if he re-tightened it after every shot. "Second Law"...no doubt.
Unfortunately it didn't dawn on me that your receiver nipple cap on your videos was what was molded into your PVC, until I watched it again and paused the end view. The firing pin looked to be a wood press fit plug with an 8-32 screwed through it and would likely disintegrate before braking the cap in a barrel plug situation...but that's only a guess.
Cheep n' cheerful but might prefer a 1911 or my Katana...in a pinch for safety. Thanks for sharing.
My 1911 does not feel as capable of stopping a person inside my house without the possibility of also hitting someone in another room.. There is a felling of "I cannot miss" with the slam action. Also, there is no safety, no trigger, nothing to lubricate or maintain. Under 20 feet it will stop anything that walks. The second shot will take about 3 seconds and no ejection is required.
"The firing pin looked to be a wood press fit plug with an 8-32 screwed through it" Exactly! There is no pressure or heat behind the 12 gauge primer. The wood plug fits loosely into the 1-1/4" pipe receiver and the head of the screw is stopped by the end cap. A nut in the rear of the plug is used to adjust the penetration depth of the dull sharpened end of the firing pin screw.
Accuracy?

Very interesting, indeed. I wouldn't mind playing with it, but I'm one of those diehard 1911 guys who's probably never going to switch. I like Speer Gold Dot in 230 gr. and figure that there'll be enough fragmentation from the hollow point that penetration of interior walls isn't a significant issue.
Ken
Me too Ken. Dad always used Speer and we've continued the tradition. The old boat tails for the 06' make a real nice group. The Gold Dots are a fine round but not sure how much frag there will be (below), based on what I've seen...and with about 360ftlbs at 50yds...it'll do! However snake shot might be a good alternative although more difficult to find these days.Quote:

230 grains at 820 fps out of a 1911 delivers about 400 ft-lbs and it is puny compared to 12 gauge 00.
1.5 oz of 00 is 656 grains at 1,100 to 1,200 fps and 2,500 on up to 3,100 ft-lbs
Shotguns are high powered man stoppers when used properly. They can beat out assault rifles and sub machine guns at close range shooting. This makes the shotgun the best possible choice and most effective choice when dealing with a close range attacker. An example is an Uzi or Heckler & Koch sub-machine gun has 340 ft-lbs of impact energy on a target, while a 12 gauge shotgun has 2,500 on up to 3,100 ft-lbs of impact energy on a target. - See more at: Best Shotgun Ammo For Self Defense & Why?

The 20 is a great self-defense caliber, and works well for people who do not like the recoil of a 12 gauge shotgun. The 20 gauge is recommended over the more popular 12 gauge for home defense use against intruders. Pick the 20 gauge 3 inch Federal shell called the "Classic" #2 buckshot (F207-2-5PK) with 18 pellets, or the Winchester "Double XX" Magnum #3 with 24 pellets (X203C3B). For shotgun owners who's firearm cannot accept a 3 inch shell the Remington #3 with 20 pellets (SP20BK5PK-3) is recommended. Each of these cartridges will provide good short range stopping power for self-defense use against people.
It is recommended that men who dislike the recoil blast of the 12 gauge along with women should use the 20 gauge. "Delivering roughly the ballistic force of two .44 Magnum rounds at once," comments the knowledgeable Ayoob, the 20 "delivers 75% of the lead for only 50-60% of the recoil". Many police departments have found their officers shoot much more accurately in realistic training exercises with the lighter-kicking but still potent 20 gauge.

I'm fine with the 12 gauge in principle, I've enjoyed shooting both trap and 3-gun, but I'd rather not be swinging any sort of long-barreled weapon around at indoor, close range targets. I'm comfortable with my .45, I hit what I aim at, and I'm very confident that it'll be up to whatever man-stopping task it's called upon to perform.Quote:

I could chat about guns (among lots of other things) all day. Please feel free to write me directly (via PM) and we can continue to explore the subject until we've each convinced the other and switched positions entirely! :lol:

Me too but think I am done here...although I did want to mention CCI still makes snake shot in lots of calibers, but haven't and probably won't try it in a 1911 for possible feed problems...however my old MKII Blackhawk 6" will make a 1/2" hole at about 10-12' in 3/4" ply with them...and I can swing it around the room PDQ...no problem! If I need more than 6, I'm in trouble anyway. :hattip: ~PJQuote:
