He took off his three cornered hat and speaking low to me he said, We fought a revolution to secure our liberty. We wrote the Constitution as a shield from tyranny. For future generations this legacy we gave. In this the land of the free and home of the brave. The freedoms we secured for you we hoped you'd always keep. But tyrants labored endlessly while your parents were asleep. Your freedom's gone, your courage lost, you're no more than a slave. In this, the land of the free, of the brave. You buy permits to travel and permits to own a gun. Permits to start a business or to build a place for one. On land that you believe you own, you pay a yearly rent. Although you have no voice in saying how the money's spent. Your children must attend a school that doesn't educate. And your Christian values can't be taught according to the state. You read about the current news in a regulated press. and you pay a tax you do not owe to please the IRS. Your money is no longer made of silver nor of gold. You trade your wealth for paper so your life can be controlled. You pay for crimes that make our nation turn from God and shame. It's number you've traded in your name. You've given government control to those who do you harm so they could burn down churches and seize the family farm and keep our country Put men of God in jail, harass your fellow countrymen while corrupted courts prevail. Your public servants don't uphold the solemn oaths they've sworn. And your daughters visit doctors so their children won't leave. Your leaders send artillery and guns to foreign shores and send your sons to slaughter fighting other people's wars. Can you regain the freedoms for which we fought and died? Or don't you have the courage or the faith to stand with pride? And are there no more values for which you'll fight to save? Or do you wish your children to live in fear and be a slave? O sons of the Republic, arise, take a stand, defend the Constitution, the Supreme Law of the land, preserve our great Republic and each God given right, and pray to God to torture freedom burning bright. As Iowoki vanished in the mist from whence he came, his words were true, we are not free, But we have ourselves to blame. For even now as tyrants trample each god-given right, we only watch and tremble, too afraid to stand and fight. If he stood by your bedside in a dream while you were asleep, and wondered what remains of the freedoms he fought to keep, what would be your answer if he called out from the grave? Is this still the land of the free? Your normal kapath conflict with the reporter. Hi Martha, yeah, hi honey, how was work? I don't know, there's a lot of cars out there in the neighborhood. Yeah, there's some really weird people going up around their ankles and people, and you imagine, boo! No, no sufficient number. Everything but the side plate, and remember you could purchase, you know, where they have the lights from a 22 to a 50 BMG. Your people how? You might get caught with what you're flying, you're getting good. Usually when we get into this conf 1919, you're gonna say that is because in the last couple of War II, now they're obsolete in either of those categories. That's where we would port normally put the M2 with the crews. The money's gonna be big. The new gun, you see the military. There's another wave of brown and they're just ginsens. Well, there's not care, everything. And now, since everybody's been seeing what's going on, when they started, I'm gonna warn you again about this, guys. You've had that happen. You used to see there's no win-win. There's no equity. It's all lose-lose. If you're foolish enough to think you're gonna make some kind of deal with these monsters, y'all better get track. Now, from Arshon, a lot of our units have, like the Mahdi's, as low in its Swept or lightest form probably around Mark. Can I jump in and get ready? Yeah, shooter who has the 240 millimeter your your your indirect fire so many of those we've the many reasons for having you were talking earlier about tooling the Chinese have figured out a way to get around Trump's tariffs because they seem to be dumping tooling right now we can buy 28 I said off eBay delivered for like $12 That is the tap and die set used for like the flash hider on an AR-15. 5.8 by 28 thread tap and die sets which is similar to the flash hider on an AR-10. Similar to what is on some bolt rifles just for around $13, $16 right now off eBay delivered. The inch buffer tube on an AR-15 lower. Buy them right now for $23 delivered off eBay. All of this is high speed steel. You need, let's say you're You've got a Remington 700 bolt rifle that uses the Inch and six to buy that and have a correct cap for that rifle. You can buy that cap for $28. And I've even seen thread chasing threads on barrels for cleanups. How this tooling is available. They had mentioned Grizzly tool. Grizzly tool sells Pacific tooling gauge. Reamer which is what Grizzly sells. You can buy that directly from Grizzly right now for most standard calibers for around $146 to $189 a piece, which is less than what Grizzly sells them for. Manufacturers that do production bought barrel making. If you're going to be truly into production barrel making, you go with carb reamers because a carbide reamer, most production utilities get about 200 barrels, carbide chamber reamer, before they have to have it re-sharp. Even though carbide is more by maybe 20% more in price compared to high speed steel, it actually gets about double the production value. So it's actually a bargain. The last thing that I would like to add, Mark, for a get off of here, and I thank you for taking my call. Okay, years ago, people needed chamber reamers. And if you had a lathe and a tool post grinder, a lot of chamber reamers were made with what's called a straight flute number 8 pin paper reamer. Every cartridge in what's called the 30-06 case size, which is the .473 case size, that case size from 243 to 30-06, 7 and 8 millimeters, 270, 260, and 308 cartridges, chamber reamers can be made out of that number 8 flute pin paper reamer. and the pen-taper reamers only cost about $20 from Wholesale Tool right now. And those are high-speed steel tools. So if you do have some tooling, you can actually make your own in a pinch. Now, it's not necessarily easy, but if you have the proper diagrams to get the right angles, you can make that chamber reamer. Now, it's also called to make the guys that find the pen taper reamers. They also made what's called a D reamer, a D-shaped reamer. You don't need a tool post grinder, but you do have to have both a lathe and a mill, because what you're actually doing is you make out of a piece of tool steel, like O1 tool steel, which is oil hardening tool steel. you make the shape of your chamber reamer and then you basically cut that part of the reamer that would be used to cut the chamber. You cut that roughly in half. Exactly in half. Basically what it does is allows you to scrape out a chamber. Now the reason I mentioned O1 as oil hardening, cool steel, that's actually also sold under the term drill rod. There's a high carbon drill rod. and it can be sharp, excuse me, it can be heat treated in the home shop. And it can be heat treated with just propane torches and using a magnet when it hits the meraschite hardness. I mean, in other words, when it won't hold a magnet, when you've reached an area very close to thorough hardness where you can properly quench it in oil. And then you can draw temper it back. Now there's other tool steels that are actually better than old ones. but they are more exotic in the heat treating process and the thorough hardening requires actually kilns and a little more knowledge. O1 tool steel will allow you to make D-shaped reamers and even specialty reamers and a little piece of drill rod, you'd buy a drill rod in three foot sticks, a 1 1 3-inch or 7 1-inch drill rod, cost you, well see half inch drill rod for a 30-odd six. The piece would cost you maybe a dollar. by the time you actually took the time to make it. So, right now we can buy tooling. One last thing here. I mentioned that I think the Chinese have figured out a way to beat Trump's tariffs by dumping stuff on the marketplace. Just as an example, I needed some AG60 threading inserts for a threading tool. And that's the kind of threading tool that you would use as an insert, an indexable insert. to be able to cut threads for almost $10 each. Went on eBay and done a search the other day. That's how I know the prices and what's out there. I was able, Mark, to buy an indexable tool that fits my tool pose with 10 indexable cutters delivered to the door for $23. This is being really clean. A clean broadcast. I know sometimes I do radio. Well, anyhow, right now we can buy this tooling. Now, for the people that want to build up long-range rifles, you can go straight to the manufacturers and you can buy the tap mandrels rifles such as Mausers, Remington, Esters, I think some Howls and some Savages. You can buy the tap mandrels where you can actually, in centric with the center line of the receiver. And you can buy these tools from the manufacturer from Pacific Tool Engage. They're like $187 to $200 and I think it's $27 right now. If you even buy those tools from Brown Nails, you're going to pay more money. Now there are chamber reamers on the market that are high speed steel that are considered solid piloted chamber reamers. Grains are available right now. Brown Nail sells them. They sell a climber brand and they sell it for the same price that climber sells them for. The cheapest price right now for that type of chamber ringer is $104. And I really would encourage people to stay away from anything made from like Serbia or Russia or China when it comes to a high-speed steel chamber ring. Because for literally $10 more you can buy a climber for about $30 or $20 more you can buy a PPG specific tool engage and that's really all I have mark unless you got a couple questions others will work they do have a lot of independent reason I made the comment that I did is the US manufacturers use a an f7 a I think it's a 846 I think the tools deal that right yeah and the tool steel that they use in Serbia is a lower grade tool right yeah Well, yeah, and see this is the deal. You can buy and maybe save 10 bucks right now by buying from Serbia, but those high-speed tools that they sell will not last as long as a climber or as a specific tool engage. Now, the last thing I'd like to add to the mention of Grizzly, right now, Bolton Tools. Bolton Tools has some sales on some lathes, and they've got, you can buy like a 12x30, a 10x30, 13 by 37 and a 14 by 40 lathe. Some of these lathes are down around the $1,500, $1,600 range and then go up as the size goes up. And the prices for their lathes and the quality of some of their bigger lathes is fairly high. Like they have a 13 by 37 lathe right now that's like in the $3,000 range and they got a 14 by 40 lathe that's in the $4,000 range. But these lathes have the inch and a half headstock diameter. So that means like you were talking about 50 caliber BMG barrels. Okay, if you do a little bit of prior barrel work to either in tapering or using a military configuration for a barrel with an inch and a half, you can actually chamber and work 50 caliber BMG barrel on those bigger lathes. And that's very important because you have a lot more range. And if you have a small business, right now you can go to bolt. tools and they will sell you some of these lathes and some of the mills that they have and you can actually finance them from in the $50 range to $100 a month for the lower end lathes. Coming out of the weapons system you're going to, you're going to, you're going to lathe slice, you're going to roll off primary work or whatever and see like, you can buy a nice lathe and a really nice bench top milling machine right now. Four grand. Now yeah, four grand's a lot of money. But here's the point, you know, of why I would start out with a lathe. Now you mentioned you picked up two lathes. Okay, here's the importance of a lathe. In 1751, a Frenchman by the name of Voson created the first dedicated metal lathe. Twenty years later, the metal lathes that he built had been modified to the point that the first powered engine was on a lathe. If you have a lathe, Mark, you can make a steam engine. If you have a lathe, your ability to make far more than gun parts, you can make so many different items. In the process of machinery for food fixing sewing machines, when you actually look at the incomes of how the world's income existed for the last 2,000 years, the incomes of people actually grew after those songs lathe was created because it allowed for people to a point of mechanization. Once we entered into the era of mechanization, people were able to barter higher wages. So literally the lathe spurred not only the industrial revolution, but the middle class that we now have because it's no longer just, you know, and hammering. It's now able to go into a more level of production. So literally everything that we see today, a lot of this was spurred because the person was made because of a lathe. just having an old lathe out there is far more than gun stuff. You know, the things that you can do with a lathe is pretty phenomenal. There's somebody saying, well, basic work, and for a number of different, you're probably stepping up. Absolutely true. Now, there are things that are either 12 by 30 or 12 by 30 multi, or in fact, it's like a 36 multi-purpose machine, both a lathe and a mill. The drawback to those are is that you can do the work, but normally, one or one or the other of the tooling your short change. Like on a multi-purpose machine normally you're bad for your machining. It's very small because it's actually a modified tool post. So normally the diameter for your headstock also normally smaller. So if you wanted to do barrel work that means you would have to do it thinner and use a stick to hold your barrel. where if you had a more dedicated lathe, like one of the Bolton lathes that I mentioned, like that 12 by 30 Bolton lathe that sells for like $2600 right now, with the stand, with the coolant pump, cooler laler right there, that would be the barriers for somebody wanting to do barrel work because the headspace is inch and a half in diameter, so that means you actually put your barrel through the headstock, you make what's called a spider on the backside to help hold the barrels true, and then you can directly chamber, chamber the barrel, threads on the barrel right at the lathe, chuck it, settle. So that means your accuracy in stuff is going to be probably within a thousandth or less. So see, all of that work can be done and this tooling is available now, but it may not be available or where we can even afford it in the future. So it's important to have that equipment now while we still have the chance to get it. Whenever we have extra model of lathes you were able to pick up. Oh, I got an old Miller. I had jobs that he did was telling me this Miller lathe is actually a commercial industrial lathe? Oh yeah, it took, we were lucky. We could see that. That machinery is probably three-phased. Now the equipment that I mentioned from bolt and tool are using one and a half horse motors that you can hook in and even this tooling is out there. Now I live years ago in the oil field industry, we had a business called the Oil Field Chase and all of this tooling off of an old steam power system and they even had a huge foundry there. So as electricity came out, then lathe came into our team by 24 lathes to go over the place that placed out of business. Now the original south lathes that they sold lathes, which is kind of rare now because most of them were in World War I. Munitions manufacturing was the capacity of lathe capacity. The lathes and cations, they would basically structure together and some of them are because we had huge equipment. Forgive me, uh, just a second. government contract is that money and I mean it was big and a dozen compared to what they are today but they huge lays was money in the bank so they'd have almost like a so this is the other thing we have a dead World War one made by running that went through the machine shop off the water if not see like early lays were driven by a steam powered with the steam system that bounce from the ceiling yep that went electric I've laid but what done is they if you've got like the ones that stand upright we have a motor underneath of them but they still Now what it is, that was a transition lathe and a lot of the old south bends maintained that because they were actually training lathes from the early central. And then when they went into the direct gear system and you get caught, uh, lathes, I hope you got an emergency switch somewhere that you can hit because you ain't going to have much. And you would be okay. Now the hobby lathes that we safety features on them, so they're not as bad as the old lathes. But yeah, Mark, right now when you were talking, that's why I had to call in. to the conversations that you're having for the day. I'm gonna use this, they had like three little legs, nothing more than two legs. Pinky dill drill presses not much gauges, so that's the case. And one of the tricky thing, man, with a wood or chamber reamers, you know, you can take a piece of stress and you can actually make a chamber die, I mean a floating die. You know, robots, we were World War II, machinery that they were, and I'm sure they got good, but you can do it with a single screw. And she did the bends and congratulations that went back to the factory the finalist and a couple of tack wells put that something you know branding when he made his firearms use very simple toolings and you know an example of a way that you can kind of tooling because set up time and energy you basically with a larger take it be the Harbor Freight tool but if you've got supple on one side plate on the other side and let's say you want to make 1911 frames well how many people know that a 1911 frame actually has a centerpiece and that the angle zine well is of angle. Do everything else and then make a broaching tool with a 14 millimeter magazine. Another tooling and then when you go to do your feed ramps you've already got a pre on the other 90 degree angle plate on the other side of your milling table and then all you have to do is just crank your milling table over to it then you can cut your feed ramp rails you can drill. Hey guys, I hate you. A lot of that work. I hate to interrupt this. We missed the top of the hour break. That's on me. I'm taking care of something here. I'm hoping everything will be taken care of by the time we get to the top of this next hour between the break of BC and the intelligence report. I just wanted to let you guys know what's going on. Okay, well, we are ready. You're still up on the air. It hasn't affected the streams or anything else. It's just something I'm doing. Very good. One last step to make sure that, again, you've got it stabled, cleaned up. You do a general, you know, maintenance. Make sure she's oiled. Make sure that everything is, the wiring is, you know, again, if the plug looks like she's the wire, we're gonna have one purpose. It's not gonna have a doodle. It's gonna do one thing, it's gonna do it over and over and over and over again. What you can do is several machines do. See, I've always argued this one to the next. There's several steps you were saying you've got to do. And say you're making 19, or let's say make it simple. A person goes out and gets many operations. We make a nine, or this is that if each individual tool was set up, quality like what we're having here. To me, I think they're good, but it's not because I'm knowing anything, but it's information that has to do with manufacturing, because a lot of people think you gotta have a bank of 20 CNC milling machines, the thing thing. Well, C machine or just a dead machine and then used other tooling. Typically, you know, if you're doing the basic drill, so that can be done on a drill. A lot of people don't know that for a lathe, you can do those with the drill press. And that way, all you're doing is increasing the quality you're doing. Things we're doing for... in wartime pre-olds and then off. We, well let me put it this way. Well you usually configure time easier. Time is involved. Yeah. The Russians were actually very good about that, you know. They knew that that. No, somebody else is asking again, I'm reading, I'm reading. I mentioned Smithy. And by what's called a $1,600 millimeter machine with a stand. Combinations, things, you'll have to add like a low-end machine. They have some beautiful lays right now that can do a lot. And those lays are in the 8 to 10 thousand. And yet they're full sheens. They're now down. a level and tools have something out and what you're wanting to do with them. But in machines are out there being the me that could run a manual machine, program and see machines tremendous work. Things just like people said, they gave them a few. That's how it was. It really was cobar man. What we recently talked about. Just can't take a beverage machine shop. God, you don't do runs your day when someone you just can't go to the machine shop and say to the, to the inside and using index. You know, you see a lot of people like, yeah, we got it. Mark. See, that's why I brought them in here thinking, well, Dering is an inch. You measure a Mauser 1.1 inches. You measure the inside diameter of your reset thing is about, the Germans figured that out. They figured that out, well, they're running about a nine. And that's why when you go buy tooling, let's say you buy from Brownells or you buy from Midway U.S., say a thread, say clean up the Mauser where you maybe booger it up, cause a scope, it was drilled for a scope. You have to be careful what tooling you get because some of these tabs actually 10,000ths oversized and they're all you clean that up with it actually a point. What was it? In other words, they were undersized. Okay, you now have 30,000ths slapped and you may screw it in, but there's a chance when you pull the really tension, run your headspace, get your headspace. That's where you need to concentrate and to make certain that when you chamber on when you change a barrel out. So, you know, you can go out good even. Yeah, comes to a gun barrel. You've got that with lots of your nose. You don't want to screw up in a hot shot, you know, Billy back butt lathe operator when you've got that in your face. You want to maintain your tolerances and maintain some precision there. And then, you know, when I started learning to run away, they're a piece of machine, I did the gun smithing because those are the people that are running paying attention to what they're doing. Remember, it's been a while, it's been a long pull away, but a tool slip. And at that time I said, well, what about what is wrong with those moths? was is it canted and you know how you've got the guy you've got your slide rails on both sides okay they were running he was when they when they ran the trough the indexers on a 19-lister model 1911 that were made that were made with aluminum frames and it's possible to make that's enough uh this is what I need I'm getting fumbled up here that's enough hard for a 1911 frame to actually make a function I think funny is enough problem with extra yeah absolutely and see uh teams now on the market where you could just uh actually actually the best way to do you take like 41 40 that would be it you can actually the kilns aren't like they were 20 years ago or 30 years ago or just cost you know two or five kiln now some of them you can even make them now for $100 or buy them okay and it was a one a lot of people when they think of Creek was in business sugar Creek had a little too little knife kiln down below $400 before they went out of business and yet they had type and you have to you know when you can get a kiln even though you got a manual set Well, you know, you have to watch for good grief. You can maintain your heat of where you need to be. Actually, it allows you to start like tool steels if you want to. M58 is, right, Mark, on tool steel. That's the steel that they used in M16 bolts. Well, the bolt, the key, when they made the AR or the M16, so what they did, they used this real exotic tool steel car, under 158. But what people don't know is, is if there's a tool steel that's available to us, and the number 7, 7 tool steel, basically a poor man's version of the Carpenter 158. It actually has better resistance ability. Thing is, with F7 tool steel, you can actually kiln a little knife kiln. All you have to do is have a steel envelope. You put your metal in there so that you have basically an enclosed air. Some people will take a little piece of scrap very inside an envelope where you're gonna heat treat in a kiln. So basically you're in an atmosphere of plain little kiln. Still you heat it up to 30. and then once you get there, you 20 minutes, when it gets to temperature, do your envelope and you just pull your part out of tool steel that will quench it. You just let it air, then you put it in 48, and guess what? And you quenched it properly and tempered it. You're ready to go. With 15 bolts, S7 tool steel. Now to give you an idea, you was talking about bare earlier, where there were semi-auto B&G's, S7 tool steel. We can afford to buy it probably was the case. true because it was something that was strictly the military industry. But the way it is now, once in a great while you can pick up a little piece of carpenter. I never have, but once in a great while you'll see a little piece of carpenter 150A available on eBay. But if you're a manufacturer and you want to buy from a mill, they make you buy minimum of like 20,000 pounds at a time. Come on. Who in the God's name is going to be able to get 10 tons of lower manufacturing? But see, like what we've been talking about here, you know, the things out there and ways for the home builder, the home survivalist, the press wants to mess around. Things out there and ways out there to do things available to us, boys and exotic steels that we can handle at the home. And there's little techniques and tricks that you can do to do heat treating. It's so funny. You remember, Mark, years ago that kind of everybody started out in a lot of these manufacturers that make these bolt rifles. that was 41.40 and then they went to the 17.4 supertating stainless and then that was the way they went. Well they're now all going back to 43.40 again. They're going back to the Mollies. They're doing that because it's easier, they can manufacture it or they can harden it, pre-harden it and then machine it. But they can get the third hardening they want, they can get the quality they need. So you know we're kind of going in this cycle. But you and I can buy 41.40, you and I can buy 43.40. So if we have the tooling, and we even have a little dedicated system, I mean one man could actually start making something if he wanted to do it. And that's been built for, you know, trailers. That ability and availability is there now, if we could just find the niche to make weapons system. Well guys, while we may not remember that what happens is that during whatever you do, it's going to be limited, it's going to be reduced. This is, with the arms industry, this direction, it's like, wow, whatever was originally cyclo, the lifespan, usefulness to be short and see who three five ten you glad you started talking about rifle barrels here in this conversation because I want to I like to give an example of that kind of parody what you're saying here the original m-1 e8 on the C scale it's about down steel you can make right now out of stress a lot of the right or like the m1 Garin was 41 for excuse me 41 50 but it was hardened to like I think a Rockwell 32 or 36 we can purchase right now an ETD 150 that is 150,000 pounds tensile strength steel with a strength of I think 125,000 basically a Rockwell 36 so we can match a 4150 barrel but we also have available to us a 4140 pre hard with Rockwell 28 to 34 and basic rifle barrel we have that available to us you know questions knew that did this For example, you want more, you want greater accuracy and longer life. For example, where this is not only a fire from the weapon. You always let go of the trigger and she could you ruin the barrel. Oh my, look he degrees. Yeah. And that's a kneel temperature. You know, if you've got 40 chrome mollies or any of the like 10-40 deals and you get it that's cooling press. However it rests.
