  1. Oh, the other thing about the festiva, was it was night and day in feel and performance, and economy at some undefined weight threshold. I could have a passenger or two, and it was the same as always. If I had my dad in there, who is a big guy, the thing was just struggling, and it was like a completely different car.
  2. I'm nothing special. I don't know much about the TDI, but I was impressed. feel free to be skeptical, I'm just reporting what I found on the trips I used it on. I enjoyed the car and was sad to see it die. As for the festiva, they came in with several different engines, and I had whichever the good one was with a 5 speed. We had a couple others in the family which were not as good, and one which was the same. The autos were garbage. I did a test driving for about a month and a half using 87 gas from arco, and ditto from the chevron which was at the time 10 cents more a gallon even. My cost per mile was identical, but the car ran way better on the chevron. I tried to not change my driving habits. So I do think fuel makes a big difference with some cars. I was a more economical driver then than I am now, but it really was a good car for me. Most of my cars since have been around 30-32 mpg most of the time. The car that really surprised me was driving a late model very borrowed loaded outback and getting 36+ mpg per the display while going over mountain passes and being kinda aggressive. I had noted mileage, and when I did the math for the trip it came out exactly what the display claimed. Older versions of the same car with less refined transmissions were much cruder and get rather dismal economy. I still don't see how they managed to get that much mpg out of such a heavy rig.
  3. reliable economy is a very freeing feature. Most of my friends got 4wd suvs for the feeling of being down for adventure. I always had econo boxes. My first car was even a ford festiva which was a better car than you would think. 55/45 mpg in a car you could afford that lasts for 450k miles and isn't made of lithium. then a crappy saturn, and then a protege 5 speed which I still have and like. It is more like 30-32 MPG most of the time, but if I am going over mountian roads at about 60, even if the car is working hard, my mpg goes closer to 42. It's getting pretty shabby due to the interfaces with antler bearing quadropeds screwing up the looks and the rear dampers are gone from having some very fat people in the back going too fast down Forrest service roads. At this point it would be dumb to dump a lot of cash into it, but it has been a great car for me. My friends always wanted to do road trips, then debated about pooling money for gas for their explorer or trailblazer or whatever. "We can go to X for the weekend, if we get another person to cram in, the gas will be $35 each..." I'd say, "let's just go. We'll take my car, and the gas will be under $35 round trip. Jump in and don't worry about chipping in on gas." economy is freedom to do what you want as often as you want. So is having a car that you don't mind getting a scratch on. I think my next car is likely to be a subaru hatch, or wagon, so I won't be as economical, but most of the miles go on two wheels the last few years anyway.

    Muzzle Brake: possible DIY?

    have your i.d. Close to bore diameter. Slots or holes work, but it's a matter of surface area that is perpendicular or more aggresive to bore, which is exposed to high pressure gasses. Pressure drops off rapidly after the first port or two. So those ports need to be designed to do the most work. Sometimes I see brakes with a few holes and then big ol slots, which is backward. A few slots close together, with enough meat in the remaining material to take the thrust of the gasses they are turning will do more than a lot of holes. My preference is angled gills and enclosed bottom. Gills need to leave stock that is somewhere around 3/16" thick between them. Also you are basically making a high pressure whistle. The shape of the vents will affect the tone, but I don't know how to predict what a less obnoxious design would be. You will probably see gas cutting and wear on the i.d. where it is doing the most work. Cut the same thing in steel, and it will do fine. People kind of make these into super high tech magic, but there are plenty of chineseum brakes that do fine in mystery steel at ~$20 each. Be sure to have clean threads with full engagement. Every bit of recoil the brake absorbs is basically thrust tugging on the end of your barrel. shallow thread engagement is a great way to strip the threading on the barrel. It needs to be solidly enough mounted that you would trust repeated slide hammer blows to never move it.
  5. I like them, but post dieselgate, VW has basically said that they can't afford to start making them again. My grampa had a 98 jetta that someone had worked over. It was fast, fun when it hit turbo, and I got 65mpg flogging it through twisty backwoods roads. Unfortunately, it had a VW transmission, which is the failure mode. I don't know what was done to it, but I am fairly sure that it had upgraded suspension and some engine mods, and probably upsized tires. I've driven gas jettas, and they felt way more understeer prone, even with what must be lighter engine blocks.
  6. He never did stand up for conservative issues, because he wasn't. He was big on defense, and that was the one point of intersection. I never liked or trusted him, but I hope I'm wrong about his ultimate destination.
  7. Think of it as cheap preventative-medicine lawyering, rather than the expensive cleaning up a cancerous mess after it is probably too late kind.
  8. For him to protect his patentability, he would need (not want. Need) a written NDA. Prior disclosure can be an absolute bar to patent. Mike needs a standard NDA form based on the work he does. It's also a good tool to keep excited inventors thinking straight about what to do and not do while fundraising, etc.
  9. I hope this picture doesn't constitute evidence of a breach of your agreement with mossberg, Mike. I'd hate to have you get burned on something like that. If you are worried about recoil, why not tack on a reinforcement plat in the critical areas? Did you have to cut a lot of meat out of the mag itself? Also, why
  10. None taken. I don't like paying gunsmiths either. There's a few things which I would pay them to do for me, most of which involve tools I don't have, or trial and error I can't afford the error on. Some things I could do, but just aren't exciting enough to offset the time and tool expense vs having someone else do it. Skilled work is skilled work, and there are diminishing returns in trying to be master level skilled at everything for yourself.
  11. He's a good guy. Not infallible, but I suppose that goes both ways. What are you saying caused the double feed? If you are saying his explanation is wrong, then it helps if you give your explanation in detail too.

    Saiga 12 Bolt Head Damage

    If my phone wasn't out of order, I would take a picture of mine to show what I mean.

    Saiga 12 Bolt Head Damage

    This feels like a comedy routine. At least one of us in this thread has a name like Zeppo or Groucho.... I'm sure of it. Turn the straight edge 90* about its axis so that it is edge on to the receiver. The way you are holding it, your hand can flex it, thus negating its purpose. It helps if the light source primarily is from underneath the straight edge so that you only see light where the contact is interrupted. Hold the gun up to the light with a straight edge as described and you will see what I mean. That will inform your picture taking. p.s. Don't get the idea that I am picking on you. You are asking reasonable questions and making honest attempts to provide the information requested. In short, you are trying to help others help you. Good job. That's actually a very rare thing.
  14. I'm okay with that, so long as it is designed to be a simple shotgun with a compact action. i.e. not a long pump action with the usual clockwork pinball machine inside. There is no good reason for why a shotgun should have any more moving parts than a military carbine. Nor should it be more complex.

    Saiga 12 Bolt Head Damage

    That's what he was asking for, but it would be even better if the picture showed holding a straight edge against the receiver flat surfaces. The amount of daylight showing through gaps is a lot easier to get a clear read on than a visual estimation of straight. Especially since some cameras have a fisheye effect (& maybe digital correction of same.)
  16. He probably has run them. Kay Miculek used to run an S12 built by Jack Travers before he fell apart.
  17. I've been involved in youtube for a while, and more importantly, I am very concerned about the power of very few companies to control access to business and ideas. I think googletube which is the second largest search engine, owned by the first is genuinely more powerful than many nations, and pretty much any political party you can name. I also think it is blind to it's hypocrisy and to it's own blind spots. Not that some of their management isn't knowingly exploiting their power... Anyway, if you want to turn of the outrage and get a level headed understanding of some recent trends, I think this video goes a long way towards understanding the situation. If you can spare a few minutes to listen, and keep an eye on his visuals, I think this would make a good discussion. Please watch through it, because a skim of the first couple minutes will not give you the full perspective. Long term, I think the ability to control the discussion and marginalize/hide ideas and companies which are unfavored is probably going to have more impact than any current wins or losses of particular political fights.
  18. I don't think I know what "gun webs" means. Can you expound?
  19. That's a nice goal, but it is almost useless if the search engines ignore or hide it.

    Tac-47 Auto Plug: Cleaning frequency?

    That seems way excessive. Just spray in any powder solvent as often as you clean the gun and you should be fine.

    Tac-47 Auto Plug: Cleaning frequency?

    Dunno, but I am pretty sure the screw is some standard thread pitch. These are all stuff I am sure you could get at any hardware store, but you might end up with a fat allen type set screw in there.

    Tac-47 Auto Plug: Cleaning frequency?

    I think somewhere after about the first 1K rounds you may need to dial up the spring pressure a little, but after that it should be good indefinately. That's been my experience. I also put a bit of paint on the adjust screw to verify that it isn't vibrating loose. As for cleaning it- I just spray it off with CLP when I clean the gun & wipe it off. No further disassembly.
  23. If the SS was button rifled or CHF, it would have the same internal stress issues that other barrel steels have. Thus it would not have any accuracy advantage as the barrel heats up. Savage SS barrels are button rifled. I forgot about that when I was writing the above. That pretty much means that they have a comparatively soft version of SS that is considered non-work hardening. If they anneal and temper, the barrel after doing the button rifling, which seems likely, then there is a good chance that they also put some work into stress relieving it in the same process though. Food for thought.
  24. It is a mixed bag of both. They are a corporation driven by profits, with decisions made by ideologically motivated management. Google/youtube is a bogeyman, because they can and do filter what information gets wide access, and what doesn't. They really do have the power to strangle businesses, and swing elections, and they have already done so. Google /YT is the first and second largest search engine, and between them have nearly 90% market share. They have a monopoly way bigger and more critical than any business that has ever been attacked on Sherman Anti Trust grounds. As for the claim that most content creators are making money- not really. It might have been true 3 years ago, but it isn't now. A lot of people dropped out after the adpocalypse, because it cost more to make even halfway decent production value content than they earned. Also the predictability of earnings disappeared. People sunk a lot of money into producing content, expecting returns on that, and are out. These weren't pipe dreams, they were earnings that they had been getting for a while and became dependent on. Now there are a very few at the top who get a bigger boost, and the bulk are unpaid. That means that the majority of producers, who used to use YT money or fan patronage to subsidize content made at a slight loss, now are at a big loss. Those who were able to replace their day job with YT, and work at it full time have had the choice to either step way up and must constantly beg for Patreon donors, etc. or they must dial way back to chat level production. It isn't just gun people. It's also hit anyone who did long format anything. YT now favors recency in their algorithms rather than quality content that people will watch all the way through or come back to. So if you spend months or years to make a very good quality video, paying editors, acquiring rights to images and music, there's a very real chance that you never recoup that expense.
  25. This is a bit dated. SS barrels tended to be better accuracy- sorta. Basically, SS doesn't like forging, swaging, etc. because even the "non work hardening" versions are work hardening. It tends to be softer than other steels, but - exceptions. Because of this, no one cold hammer forges, swages, or button rifles SS barrels. Cut rifling only from annealed blanks. This meant that SS barrels only got whatever stresses in them came from the tempering process. The metal is probably on the softer end of the steel spectrum, and may fail at lower temps. It will have a shorter life than tougher carbon steels. However, it isn't a spring that wants to flex as it heats up. This means that for low volume target shooting, you will tend to have less point of impact shift as the barrel heats. It also meant that all the really hard core match shooters wore out a barrel a year. SS was about reducing POI shift during rapid fire strings, not about more accurate from a cold bore, or on slow fire. any of the popular metals were capable of making equally good small groups, from bench style shooting. If you are thinking from a 1980s / 1990s mindset, if you wanted serious accuracy to do high power match shooting or similar, you probably got something like a heavy profile white oak armament barrel. If it was super high velocity cartridge, about the time you really knew your gun, throat erosion was looming, and you had your next barrel on order. Maybe you had Cryogenic treated barrel, which was a sort of half measure way of stress relieving the steel after it was already made. This added a lot of cost, but would reduce POI shift. Now for why the info is dated. Heat treating has improved a lot since then. So stuff made to 1950s or 1960s military standards are chrome lined and primarily optimized to not fail at extreme high temps as soon. - really extreme use, at the expense of every thing else. Including at the expense of barrel life when shooting short of the red hot state. Chrome lined CHF still has a slight edge on machine guns running glowing barrels for longer. Let even slight cooling happen i.e. 20 second pauses in fire, and CHF doesn't outlast modern button rifled nitrided barrels. I read a few studies that private companies and the military had commissioned. The data showed that even heating up ARs to the point where the hand guard was smoking and too hot to hold, but with basically pauses that equate to the amount of time for a general mag change the nitrided barrels with modern steel outlasted the CHF barrels. Outlasted meaning: more rounds until accuracy degrades, more rounds until the gas port enlarged, more rounds until crown erosion, and more rounds until throat erosion. Since the mid century cold war generation, better steels have been developed, and more consistent ways of heat treating. And the kicker is stress relieving the barrels in the process of the heat treating. Now you can have a harder steel that resists wear more than the old tech military barrels. It can have nearly the same extreme heat failure behavior, but perform a lot better earlier. I have never heard of stress relieving being offered to CHF barrels. I don't know the exact reason, but I suspect it's that the heat and cool process might adversely affect chrome adhesion. I don't see why they couldn't stress relieve before chroming, but I am not aware of anyone offering barrels made that way either civilian or military. Moreover, companies like glock, faxon, ballistic advantage, etc. use a nitride process that has the stress relieving built into the heat treating and finishing process. And nitrided barrels can be more resistant to corrosion than some flavors of SS too. The guy from Faxon has published a lot of the data on the behavior of various steels on ARf, and with inrange. I've seen/ listened to enough industry guys, even those who sell cut rifle barrels in SS confirm his claims to say that the gist of what I put above is undisputed. Whatever advantages SS used to have over black barrels is now moot. The durability of CHF vs high quality nitrided is moot. Chrome chambers are proably less prone to sticking with powder fouling, dirt and heat cycles, but not by a lot. Simply put, a lot of the off the run of the mill barrels right now, are more consistent than super special custom match barrels from the 1980s, and the difference in quality from a standard barrel from a good brand and their super match special sauce is a lot smaller than it used to be. I'm not saying a no-name nitride barrel of of davidson defense or ebay is superior to an SS match barrel, but from a reputable brand listing one of the known good steels, there are almost no downsides to the current gen nitrided barrels vs other options. So as a life time, indoctrinated from childhood fan of SS, and derider of black guns as delicate rust prone toys, it mean something when I would say that SS isn't really the best choice anymore. I got my dad a nitrided gun for his boat gun this year. It probably spent the summer coated in salt water and acidic fish blood. I have a heavy SS fluted barrel on my AR, but if I were picking one out, it would be lighter and it would be a stress relieved nitrided. SS fluted is still the best looking, but the next firearm part I am likely to buy is a faxon light profile 16" 300 bo barrel.
