  1. The idea of the thought experiment was to not use conventional mechanical parts. So a differential would be cheating. You have a good point about the torque converter, it is pretty much dead weight. I guess the pump could have a stall speed higher than the idle rpm. Though I think heavy equipment is fundamentally different from, say a car. Since they require much higher reliability, roughness and lower cost. As far as I have seen, most hydraulic driven heavy equipment use air cooled hydraulic motors. This would be a no go for a car. A liquid cooled motor would probably deal
  2. Thanks, I sadly do not have a lot of practical experience with hydraulics, so this was very helpful. I had a idea about a sort of hydraulic transmission. The idea was to use hydraulics instead of a mechanical reduction gear and differential, and then couple a accumulator to the system to absorb breaking power for later use. I have heard that hydraulic regenerative breaking has a efficiency of 90% compared to the electrical at around 60%. I also wonder if it is possible to completely lock the motors (assuming they are completely sealed, no run off), and use them as a
  3. I have a curious question: Lets say I have a car and I want to power it with hydraulics. A engine is connected to a hydraulic pump via a torque converter. The hydraulic pump powers two motors that are plumbed in parallel. Would this work like a differential, or would a actual differential be needed? Also, Could I use a pump/motor setup as a reduction gear?
  4. Honestly, I think a machete or a sami knife would be better, chops just as well in my experiance. I rarely use my hatchet. I have actually chopped down more trees with my spade than with the hatchet.
  5. Some guy wrecked the Trump National Doral Miami Hotel lobby (NSFW): https://www.liveleak.com/view?t=kqoSt_1540401872
  6. The biggest newspapers in Norway are complete crap for the most part. They mostly recycle articles from abroad, to the point that they don't even care to properly translate it, and instead use norwegianized English words. Most articles are about celebrities, and useless junk from abroad. Its so bad that you have to read a local newspaper to get national information. We even had "murica experts" to give people "informed opinions" on the "political landscape" in the US. Turned out most of them were no more knowledgeable than your average tourist. One popular theme is "vesle ma
  7. Norwegian media spoke with a "expert" named J. Reid Meloy. I use quotation marks since Norwegian media tends to call anyone with knowledge of a subject a "expert", though this one is actually a forensics researcher. According to him, this is probably a person with deep hate for the targets. He thinks this most likely is driven by ideology, most probably a white nationalist. He thinks the person could be military and police, because of the technical knowledge needed to build a bomb. He thinks the election is the cause. Source: https://www.aftenp
  8. Indeed they are, I watch them once in awhile for the entertainment. I feel most of his videos are of good quality, so just pick some topic you find interesting. Though I would not call the Kalergi plan unattainable. I actually think it is a genius plan, in a psychopathic genocidal way. Ethnic groups a problem? Simple replace them with a mixed of new people that don't really identify with the nation. How not to start a race war? Simply make sure the recipient country has low birth rates and make sure the sender country has high birth rates, and don't do it to
  9. If you are talking about Black Pigeon Speaks, then actually no, I just saw the title and wondered what it was, so instead of watching his video, I actually looked it up. He is a bit too propagandistic for me. Though I have to say, the 1900s were really a interesting time.
  10. Today I learned about the Kalergi plan, which is basically a reverse nazi plan for the unification of Europe from the 1920s
  11. I was simply making sure that people understood that he had mental illnesses, apart from being trans. I don't really care about whether or not it is a mental illness, not really worth discussing with left wing fanatics (Note: Not calling you a left wing fanatic). They are only 0,1% of the population, I have better things to worry about.
  12. A mentally ill (not referring to being transsexual) trans-woman. Nothing out of the ordinary here, statistically speaking.
  13. Slapping a mill bit on a industrial robot? Hmm, thats too bad.
  14. I am not trying to dispute that 3D printers are slow, I am just brainstorming. In theory, you could mill your handguard in 5 seconds if you wanted.
  15. Good point. Though, it made me think, what about 3D printed aluminum? You could accomplish new types of geometry with it. Crazy shapes like these which are pretty much impossible to cast and very expensive to machine: Another thing would be carbon fiber construction.
  16. Coming back to this, wouldn't it be possible to monitor the temperature of the mold and keep it heated at a constant temperature? Can't simple thicker plastic be used to make it more rigid? I was more thinking of low volume runs or something like that. 3D printing has come a long way, I remember a 3D printer that uses light to harden a resin into a shape, which is then cured, this avoids the layered approach which makes the plastic much stronger. I like hex keys, probably because every fastener in my workplace is either hex key or a bolt. Though, I think
  17. Ah, I see. Why not use a hex key? Easy to manufacture, works with power tools with no problems, and easy to store in the rifle. In case of a total loss of hex keys, just raid a local IKEA for a century's worth of hex keys. 3D printing could work. But is there no plastic handguards?
  18. Now I know why all modern rifles use slots instead of holes. Out of curiosity, how is the handguard mounted to the rest of the gun? Just two fasteners? Why not have one on the top and one on the bottom instead of two at the bottom? Or have the handguard slide in on the rest of the gun, and secure it with one fastener? And what type of fastener do you use? Hex key?
  19. That's good. Since the handguard is made by extruding the aluminum, have you considered making it a circular instead of hexagonal to improve its strength and reduce the material usage? Also, instead of using ovals to perforate the handguard, I think a 60 degree staggered formation of circular holes would improve the strength again. Something like this: Please correct me if I am wrong
  20. Good point, I guess no-one has had problems with aluminum?
