After reading the article I, learned about the importance of; fire lapping and Electropolishing to increase accuracy. Having no replacements for the barrels and having a low budget, Joe Carlos found an affordable way to improve the accuracy of the rifles of his unit. It’s very important in this career field that we minimize the cost where we can, without sacrificing the accuracy and beauty of our product. This article also showed me the importance of keeping proper records and inspecting all parts of the weapon instead of just looking at the barrel as being the only problem. After the writer inspected all parts of the weapons, he saw improvements when; properly mounting the barrel extension and upper receiver, using match grade bolt carriers, fire lapping and using Electropolishing. …show more content…
This week I, learned that when inspecting a rifle barrel to look for pitting especially near the crown as this will minimize my accuracy. I, learned that using a cleaning rod can cause damage to my rifling, making my projectiles not fully stabilize. Having a rough or not broken in barrel, can tear at my bullets and cause more fouling. Until reading the article, I would have never thought to Electropolish anything on my rifle. I, now understand that it will aid me in accuracy and clean up. I, agree with Joe Carlos in that the Electropolishing process is effective, but it seems to be very wasteful. My warranty or a customer’s warranty will be void by utilizing this technique as well as fire lapping. By using the Electropolishing or Electrochemical polishing, it removes material, polishes and deburrs metal. The surface is oxidized and dissolved, but it doesn’t cause mechanical
One weapon used in the Civil War is a Sharps Carbine. It was developed primarily for Calvary, because of the shorter barrel. They were much easier to handle on horse back than their longer brother the Breech-Loader. Sharps were preferred because they could be loaded on a moving horse, something virtually impossible with a Muzzle-Loader. Also, Breech-Loaders carbine which fired moisture proof metallic cartridges, where more reliable than rifles that fired paper cartridges. As I said be fore it is easier to load a Sharps than a Muzzle-Loader. A Muzzle-Loader took 9 long hard steps just to fire one shot. Even the most skilled solder could only get three rounds off in a minute on the old Civil War Muzzle-Loader. And No wonder. After each shot you have to (1) steady the gun on the ground take out a new cartridge out of a belt pouch. (2) Tear open a piece of paper with your teeth. (3) Empty the powder in the barrel and insert a bullet in to the muzzle. (4) Draw the long “rummer” out of its carrying groove under the barrel. (5) ram the bullet all the way down. (6) Return the rod back to its groove. (7) Lift the weapon half-cocked the hammer. (8) Fully cock the hammer, aim, and finally,(9) fire.
Disasters can be so impactful; some can forever change the course of history. While many at the time thought this story would soon pass, and with it all the potential bad publicity, the story of the Triangle fire spread quickly, and outraged many people. On a beautiful spring day in March 1911 when 146 workers lost their lives, a fire would prove it could do what years of reformers had failed to do, get the government on the side of the workers. I would argue that the fire largely impacted the country. Specifically, the Triangle Fire ended up changing New York’s interconnected political and economic scene, and spurred on the creation of stricter safety codes. For the first time owners would hold responsibility for their actions. Max Blanck and Isaac Harris; being indicted for manslaughter was proof of this. Social change seemed to be spurred as well; the general public and newspapers would come back the workers of New York. Large institutions would suffer as well. Tammany Hall would be feared less and less by waves of new immigrants. The largest change brought about by the blaze would be legislation. Twenty-five bills, recasting the labor laws of the state

...ist must keep his tools scrupulously clean. The brushes are dipped and wiped throughout the painting session with brush cleaner to keep from contaminating colors with residue from previous paint. Use a beater rack to remove excess thinner from brushes after cleaning them.
The City of Detroit, Michigan, seems to be a city on the decline in America. Job prospects some of the lowest in the country and one of the only cities to be shrinking, rather than growing. There are a lot of problems Detroit is facing, one of them is there incidence rate for fires. Detroit is the number one city in America for house fires, not to mention their high rate of fires in the many vacant buildings throughout the city. There are many socioeconomic factors with the city that make the incident rates rise, and response less effective.
This innovation, highlighted by Daniel Headrick as a key tool of imperialism, allowed for the abandonment of primitive guns, which behaved and worked similar to a small cannon (Headrick pgs. 231-63). See the This made guns a much more viable option in combat, as there was no longer a need for the antiquated and lengthy loading process of a musket or flintlock pistol. The introduction of rifled barrels also increased the efficiency and accuracy of firearms. By carving spiralling grooves throughout the barrel of a gun, the projectile could be spun, increasing its speed and giving it a straighter path. This technique has been adopted in nearly every modern firearm today, as it dramatically improves the accuracy and velocity of projectiles.
Altho somewhat similar the two stories are very different in many ways. The first story is called “Mystery of Heroism” by Stephen Crane and the other one is “To Build a Fire” by Jack London. Both of the books are part of the short story genre and realism stories. The author's purpose for writing the “Mystery of Heroism” is to tell a story about a brave man who went to get water for a dying man. The purpose for writing “To Build a Fire” is to tell about a man and his dog and how he tried to fight the below freezing temperatures to stay alive. Both authors use realism because they want to tell real stories about people and how they had to overcome struggles in their lifetime. These two stories have similarities but they are way more different than anything else. One of the stories is about a man who has to overcome fear to get water for a man.
Next Blood lists some barrel turning and fitting procedures such as “facing off the center holes, drilling new center holes, turning a relief cut on the muzzle, the basic lathe step, turning the breech O.D., marking the breech and thread tenon length, turning the thread tenon diameter, turning the thread relief groove, facing the thread tenon to length, counter boring the breech face, shaping a coned breech, reaming a chamber, threading the thread tenon, determining correct chamber depth/headspace, finish chamber reaming and head spacing, chamber throat length, crowning the muzzle, milling the extractor cut, assembly of the barrel and receiver”. The author finishes after listing additional topics like “fitting a barrel to the single action, blueprinting a rifle action, chambering for the twenty-two rimfire cartridge”. After reading this article at least 5 times I am still unsure of exactly what the purpose was, it all seemed to be trivial information and then it ends abruptly making me wonder if I somehow didn’t get the entire
To reassemble the AR-7, reverse all steps taken. All weapons shoot differently with different ammunition. The shooter should conduct research before buying .22 LR in bulk. Some maintenance issues with the AR-7 is the .22LR residue near the bolt, lead nose jamming against the top of the chamber, denting due to
This was wasteful and perilous. By 1863, on the other hand, there was another choice: alleged rehashing rifles, or weapons that could shoot more than one slug before requiring a reload. The most popular of these weapons, the Spencer carbine, could shoot seven shots in 30 seconds. In the same way as other Civil War advances, these weapons were accessible to Northern troops yet not Southern ones: Southern production lines had neither the gear nor the skill to create them. "I think the Johnny's [Confederate soldiers] are getting shaken; they fear our rehashing rifles," one Union trooper composed. "They say we are not reasonable, that we have firearms that we load up on Sunday and shoot all whatever remains of the
There are thousands of models of shotguns, who knows how to choose which one for the right job? The most common gauges of shotgun are 10,12,16,20, and 410. This experiment can test any of those gauges against each other, but the two that were tested in this experiment were the 12 gauge and the 20 gauge, as they are often compared for different jobs. If that’s confusing, don’t worry, it won’t be after this paper.
You here it time and time again from These Gun-snobs "well maybe could have saved up a little more and got something better".Well "better" is like beauty its in the of the beholder and, The 2 problems with this as soon as it happens. The first problem is they feel that they've wasted their money. The second is they become embarrassed and often times won't shot at all or not as well as they could.
3. Pay attention to the feel of the trigger pull and reset. This will get you acquainted with how the firing and reset mechanisms work on your gun when you are shooting for real. You won’t be surprised by the trigger reflex action.
When we think about it all current models still in some fashion still use the same complex design that the started with in the 1500's. Of course they aren't the exact same but they follow the same line for design. Of course with new technology comes new parts and new firearms. I have always been very interested I the history of firearms. Learning and reading about the evolution that the firearms industry has encountered is literally mind blowing. Also the thought of where it will continue to go is even more interesting. My goal is to be like John Browning and become the next future genius gunsmith firearms inventor. If you are interested in learning more about the history of firearms there is tons of video's on YouTube that are very great and extremely knowledgeable. I would recommend this to my fellow students.
